If you’ve been experiencing any recent engine issues like stalling or accelerating with your vehicle, it’s possible that your vehicle has a faulty accelerator pedal position sensor. The accelerator pedal position sensor reads the position of the accelerator pedal and sends the information to the engine control unit (ECU or PCM). This unit uses the information to then control the rest of the throttle body, an important part of a car’s fuel control system. Without the sensor working, the engine’s fuel-air ratio will be affected and the vehicle will have trouble running smoothly.
Here are 5 signs that your car’s accelerator pedal position sensor is having some problem.
1. Acceleration is delayed
One of the telltale signs of a problem with the accelerator pedal position sensor is slow acceleration. If you notice a delay between the time you press the accelerator and the time it actually accelerates, take your vehicle directly to a mechanic. Also, if your car tends to wobble during acceleration, a bad accelerator pedal position sensor could be the main cause of this.
2. Engine stalled randomly
Another obvious sign of a poor accelerator pedal position sensor is random engine stalling, which happens regardless of whether your vehicle is idling or on the road. Of course, engine stalling can be caused by other problems, but if this happens along with any of the above other symptoms or if it becomes a regular occurrence with your vehicle, then you need to must consider it.

4. Trouble shifting gears
If the accelerator pedal position sensor does not report the correct accelerator position, there may be a problem shifting gears when you accelerate or slow down. Only this sign could mean a faulty transmission and costly repairs, but if you’ve noticed acceleration problems, you can be confident it’s a position sensor problem. accelerator pedal position.
5. Check engine light is on on the dashboard
The check engine light comes on indicating that there are problems with the engine and related systems, but one of the potential reasons it lights up is a faulty accelerator pedal position sensor.
