Recognizing The Accelerator Pedal Position Sensor Problems
A failing accelerator sensor directly affects the response to the gas pedal and gas mileage, leaving the problem only worsens the issue. So here are the symptoms that you read and identify if the problem exists with the accelerator pedal sensor.
Your car does not respond well when the pedal is pressed
This is one of the accelerator pedal position sensor problems where no matter how much you depress the pedal, the car does not respond accordingly.
This situation easily signifies that the problem lies with the pedal sensor. Hence, if the same is happening to you, this is a clear sign that your accelerator pedal sensor is the culprit.
Your car doesn’t seem to grasp speed

No matter how much pressure is applied on the pedal, the car does not seem to keep up with the action.
This means that your car stops going faster after a point regardless of the pressure applied on the pedal. This is because the pedal sensor fails to send signals further.
Your car does not even buzz
If the accelerator pedal does not work at all or if your car does not even buzz, then the pedal sensor is bad. No matter how many times you depress the pedal, it just does not seem to be working.
You experience low gas mileage
Low gas mileage is a common problem whenever the accelerator sensor goes bad.
Sometimes, you do not see much difference in throttle or accelerating the car, but you notice a mileage that is too low that it should not be.
This is another sign that you can have your car for the accelerator pedal sensor checking.
If the car doesn’t idle smoothly
