6 Most Common Crankshaft Position Sensor Symptoms

All the modern vehicles have the crankshaft position sensor. It is a component for monitoring the crankshaft’s rotational speed and position. It also sends a report to the engine control unit so that the latter can make the right adjustments should anything is malfunctioning. There are several failure crankshaft position sensor symptoms that you should pay attention to. Many engine models stop functioning if this component fails to send accurate signals.

The Most Common Failure Crankshaft Position Sensor Symptoms

The speed and position of the crankshaft are two key parameters that the car’s computer uses for engine management calculations. So, you may understand how important it is for the sensor to work without any glitch. Let’s learn about some crankshaft position sensor failure symptoms so that you can take action when there’s a problem.

1. Check Engine Light Is On

It can come on for various reasons and sensor problem is one of crankshaft position sensor symptoms. Sometimes, it stops working due to overheating and causes the check engine light to turn on. In that case, cooling down the engine for some time will cool off the sensor too and turn the light off. Otherwise, you will need a mechanic to check the car’s computer to determine the source of the trouble.

2. Vibrations in the Engine

Vibration from engine is usually the cause (photo source: piqsels)

A failed sensor means no monitoring for the crankshaft position. It causes the engine to start vibrating heavily. Ultimately, the juddering can affect the engine power and mess with the recording of mileage.

3. Slow Response from the Accelerator

The accelerators sometime cannot follow up (photo source: quebec95)

If the sensor is facing any trouble, it won’t send correct information about the position of the cylinders. It means there will be a gap between the computer receiving data and applying it. For this reason, the accelerator hesitates and does not give a real-time response.

4. Erratic Starting

It’s one of the most serious crankshaft position sensor symptoms. The computer receives a malfunction code when the sensor is completely gone. The symptom starts with difficulty in starting and leaves the car dead one day if you don’t get it fixed. The starting problem could be the result of electrical connection or circuit problems too.

5. Misfiring of the Cylinder

It’s a common response when your car experiences some crankshaft position sensor symptoms. Failing sensor cannot provide correct information about the piston position, causing one of the cylinders to misfire. An issue with the spark plug will also draw the same response. However, if the problem persists after handling all the other issues, the sensor is likely to be the culprit.

6. Stalling and Backfiring

It’s another issue that indicates a malfunction of the sensor, and one of the crankshaft position sensor symptoms. In this case, your car will still run but the engine will turn off after some time. The misfiring will also occur the same way. If you keep ignoring the signs, the engine will shut off permanently.

  3. Cindy says

    I had crankshaft position sensor replaced after 1997 town and country stalled. The next day I picked up my van; the engine stalled before I left the parking lot. I had to get the crankshaft position sensor replaced; because the first crankshaft position sensor was defective. Today, similar problems again tried to start but didn’t. Start a second time, Tennessee minutes later a slight jerk in acceleration, and engine light came on, two hours later, start engine, drove and two minutes later engine stalled. Could this be same problem?

  4. Rachel Williams says

    I am reading your blog and I am really enjoying it.

    I am not car savvy and I have a weird situation.

    My Toyota Camry engine blew up the day after a service and oil leak was fixed.

    The insurance company has declined my claim. But, I think they are still related.

    They said that the failure of the engine was due to the falling out of
    the bolt securing the VTU.

    But, I have been told that bolts don’t just “fall out.”

    If you can help me, please let me know. I can send you more documentation
    and photos.

    Can the crankshaft sensor get overheated and make the car not wanting to start?



  7. ivan says

    I have a bmw x5 and the signal is reading between 0 and 12 v, could be a ground issue in some cable? I get signal to high code in bank 2. should add some resistor between signal wire and ground to turn it about 5v, and retry? the car is not starting.

  9. Gabino tobias says

    I have a 1993 Jeep Cherokee sport and one night as I drove 20 minutes from my house to my buddy’s house i noticed I was low on fuel and instead of stoping at gas station I went to him first thing is that Once I got to his house I turn of my Jeep and when I tried to start it again it would not start At first I thought it was that I had no fuel after I went to get fuel in a 5 gal gas tank and put it in there still nothing so I’m just wondering what it could be the fuel pump comes on when I put the key forward . So I know is not that any suggestions on what it could be maybe a Fuel injector a bad coil or a sensor

    1. Sage Pope says

      I had this happen to my 1988 Cherokee sport. had just done plugs, wires, coil, fuel pump and O2 sensor. I pulled the plugs and noticed Cylinders 1,2, and 4 have almost no fuel, while cylinders 3, 5 and 6 have fuel. I think when the fuel gets that low, and especially with old injectors, that the injectors get to hot and fry themselves. Check for fuel coming out of the injectors. Ive already orderd new Bosch 4 port injectors, and im going to install them tomorrow. If its not that, im going to check the MAP and CPS sensors and hopefully that fixes the issue.

  10. Alice Chung says

    I have a 2005 Honda Jazz with automatic transmission. Servicing has been carried out recently. There is still some 30,000 Km before the change of gear oil is due. The car has been jerking and stalling so a new crankshaft position sensor has been put. Unfortunately, the problem is still occurring. I shall most appreciate to receiving a professional help and advice. Thanks so much.

  11. A fool says

    Probably a stupid question say your engine does shut off permanently would changing the senser get it to work again or is it bye bye car and get a new one

    1. Sage Pope says

      Unless it manages to bend a connecting rod, seize, or start dropping valves, it will be fixable

  12. Jess says

    I have an Audi s3 with a cam sensor problem….replaced it with a brand new one but still getting the engine management light on and the code for cam sensor?? Checked wiring and that’s fine don’t know what else to do ?

    1. Sage Pope says

      Clear the code and see if it resurfaces

    2. Red says

      I’ve got exactly the same problem with a Audi Allroad V6 2.7t engine. Did you solve your problem and what was the reason for this problem? Timing belt jumped a tooth, chain guide broke down? Did you check compression?

We got the bottom one replaced but after about an hour of driving, the dashboard shows a battery light icon and the engine stalls, and after a few minutes it can start again and does behave same way when the engine is hot. The engine also vibrates ocassionally on acceleration .Please help me with the right advice on how to go about it, and specification of the sensor it would also require. Thank you!

    I have a Mitsubishi Grandis 2001(eng: 4G64), import it from Trust Japanese Vehicles, my car does not start anymore, it cranks only, got mechanics to check Fuel Filter, Spark plugs, ignition coils, camshaft sensor, throttle sensor, ECU and all seems to be working, but Crankshaft Sensor was not checked.

    Before all this, I washed my car engine and the only problem was, the car has no engine power when accelerated. Car starts smoothly but no engine power, when the Fuel Filter was removed and checked that’s when the having this problem, it only cranks but not starting.

    Please help.

    I didn’t have a problem with my 2006 town n country till my car place disabled it bc of my late insurance payment . To make a long story short I had the GPS taken off cuz my mechanic told me that was interfering with it starting n staying started,anyway then I had the fuel injector replaced n its running worse than before ,no power feels like its gonna stall when I’m coming to a stop doesn’t turn over on the first attempt like before it takes like 4 time n I gotta put my foot to the floor n I smell gas my check engine lite is on again after mutable time since I’ve had it. I’m at my witty end.

    Hi my name is Dave i have got a 2.2 litre ford transit tdi have a mega problem with my vehicle firstly it started conking out and then it was difficult to start up again so i had to turn all the POWER OFF to get it started again so we put it on the DIAGNOSTIC MACHINE AND it came back as PO335 CRANK SHAFT POSITION SENSOR ; A ; CIRCUIT.
    so i changed my crankshaft sensor. with a new one from FORD and we thought that we sorted out the problem because it was only conking out after 3-4 days so we put it back on the DIAGNOSTIG machine and it came back not with 1 problem but 2 problems with the SENSOR. So i am asking your advice what am i meant to do 1 mechanic thinks that it is the timing chain and he wants to fit a new one but my vehicle is only 5 years old. i hope that you can help me cheers DAVE.

  28. Betty Polasky says

    I’ve got a 1996 Jeep Grand Cherokee county which I’ve recently had to get the crankshaft sensor replaced. When I got it back from the shop it ran for about 1 hour very rough though. Now it is leaking transmission fluid heavily and running much worse then when I took it in. It will not leak if I take the cap off the radiator though. I really need some help here.

    1. Brian Stockham says

      If you haven’t already had this diagnosed, there apparently is at least one leak between your radiator and transmission cooler (they are the same unit, but the transmission cooler is a separate, but adjoining “container” at the bottom of the radiator shell. The radiator is supposed to carry heat away from the transmission cooler. It sounds like there is a leak or rupture between the two, and the steam pressure in the radiator is forcing transmission fluid out from another leak.

  31. Kit Hannigan says

    I am glad that you explained how a delayed response from your accelerator can point to a problem with your sensors. My son travels all around the country to look for landscape photos to sell off of the internet. His business depends heavily on his vehicle, so it will be wise of him to take notice of any abnormalities of his car and taking action immediately. Should he experience any delays on his accelerator, I will be sure to advise him to get his vehicle into the car repair shop immediately to avoid prolonged downtimes for his business.

    turning the ign key sometimes nothing happens when attempting to start the car. If I put the car into gear and move it forwards, then select neutral then most times it will start.

  39. John says

    I have a question about troubleshooting after a crank position sensor was replaced on a Jeep Cherokee Grand Loredo 2002. I replaced the sensor (what an absolute pain of a job it was!!!) and after replacing it when I tried starting the engine it feels like starting an old style car with timing way way out. It almost started a few times but has trouble cranking and backfires.
    I replaced with a new sensor that had the paper gasket for clearance but what I’m wondering is whether the symptoms may be because the sensor is too far away from the flywheel. In retrospect, maybe I should have made sure the sensor was pressing against the flywheel before tightening the retaining bolt/screw.
    The concern now is if the sensor was against the flywheel the temporary paper gasket will have bee ground off and pushing it closer to the flywheel will damage the sensor.
    Any advice on whether the problems would be caused by the sensor being too far away from the flywheel and how I could check this without removing the sensor again. It really is a painful job that would be so much easier if I had thinner forearms : )

  44. Mike G says

    We recently had a mouse that decided to chew through the wires going to the camshaft position sensor on our 2014 Toyota Rav. It happened at about the time for the 50,000 mile service checkup so the service engine light has been on for about a week. One day I saw a New yellow warning that said Check Engine Soon. So I headed straught fr the service shop. Almost by accident the tech noticed that the check engine light would not go off and looking very closly at the CPS connector he saw that all 3 wires had been chewed through just a scleanely as a wirecutter. It was an amazine sight to see how tightly the cut was made. Under the circumstances i am hoping a new pigtail wil solve the problem (much less expensive than a new sensor 🙂 !
    My question is why didnt i see a single tiny bit of malfunction during the time i have been driving yet had no camshift sensor. Everything worked perfectly! Does this mean Toyota is an extremely wellmade vehicle or was i just very lucky? As a side question why would a mouse do something like that anyway?

    I have a fiat panda 2009 , my engine light started blinking & the engine was cutting out at low speeds or when going over bumps . I then broke down as the engine cut out completely & AA came out & they managed to start it .this time engine light stayed on , AA diagnosed a crank sensor fault . Had new sensor fitted & warning light cleared & no faults were then detected . However when I then drove it , the car had exactly the same fault & cut out again with engine light blinking , then cut out altogeher again !!!???

  49. Carole Tune says

    Hi there, please help me. I have a 2004 Honda CRV 2.4 VTec 165,000kms. Has run perfectly for the last 10 years, never any problem. Then I was having trouble with it not starting at first go, engine would crank over but not start straight away, but eventually would. So, though it might be a dud battery, which I had replaced.
    Seemed ok for a short time, then started doing it again. Took to a mechanic who thought the only thing could be the crank sensor, which he replaced 4 days ago. NOW the same problem is back, got the car to start, reversed out of the garage then back in & when I put the car into Park, the engine shut down completely. Couple of goes, got it started again, put it in reverse and engine cut out straight away. Now I am too scared to drive it in case this happens when I am driving. Does anyone have any ideas as to what to look at now. Any advice would be greatly appreciated.

    Hello I have a question about my 1997 kia sportage I bought the truck already misfiring and no good starter fixed starter and change the coils and spark plugs, and wires also it got a little better but some other problems started showing up it will start! But idles very rough. And when I’m driving it will out of no where it will just die and If I try to start it sometimes it will fire right up some times I have to keep cranking with turning ignition on and off then it starts up!! and also when I unplug my mass air flow sensor that’s when it idles only other wise she stalls right away so I put on new mass air flow still no difference and on my diagnostics machine ( code reader) only show mass air flow and a code. P1614 wich I believe is computer related and my question is could it be my crank shaft sensor? or is my E.c.m no good ? And also it just presently started when my SUV is started all my dash lights will stay on even the key ignition chime(the buzzer) I’m really lost of what to try next on the vehicle and really can’t afford to keep throwing money on a vehicle if it’s not going to fix it !!I have a diagnostics machine(code reader) so if there is some kind of testing I could try? If you could point me in the right direction would be very much appreciated!! and thank you in advance!!

  60. Nick Hocker says

    I could desperately use some help here. About a year ago, my check engine light came on, the code showed the issue was with the crankshaft position sensor, so I had it replaced. Things were fine for about 6 months, then the check engine light came on again, the code was once again for an issue with the crankshaft position sensor, so I took it back to the same mechanic, who thought it could have just been a bad sensor, and he replaced it again, for free. Things were fine for about another 5 or 6 months, and then about 4 weeks ago, the check engine light started coming on again, and once again the code was for a the crankshaft position sensor, specifically, P0335 Crankshaft Position Sensor: A Circuit Malfunction. I went back to the same mechanic (who does have great credentials), and this time he said it cant be the sensor since he replaced it twice. He then stated I should take my car to an electrical shop, but that I was looking at paying about $120/hr and probably being without my car for a week to 2 weeks, just for them to try to diagnose the problem. This is not an appealing option, either monetarily or time-wise. All the symptoms I’m experiencing do seem to fit with a bad crankshaft sensor: the car stalls frequently when I am stopped at a stoplight, it sometimes starts rough, it idles high, and sometimes lurches during acceleration. Any advice on what to do at this point would be greatly appreciated. I have a 2009 Pontiac G8 GT, with about 75,000 miles on it.

    In y honda accord 2018 , my car showed the engine sign. It came wit h the triangle sign as well. Also my car slew down and did not speed up also did vibration. When I checked it with the computer it showed crank shaft and misfire. I took my car to get tuning so it can fix the misfire cylander. After tuneup my issue remained and I changed the crankshift sensor. My car start to run smoothly and showed no issue. However after few days problem came back. but then problem sometime comes and something car run smoothly. I took to another mechanic he told me to put V tech gas. After that my car started to run fast but I could feel car is not that smooth.
    So my question is now what else is going on in my car that car sometime show the issue and sometime it goes away.
