Will a bad TPS cause a car not to start?
When a TPS goes bad, then the car’s throttle body won’t function properly. It could either stay shut or it won’t close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won’t start.
Can a bad PCM cause a car to not start?
This can be caused by several different PCM errors, but may also be an indication of something wrong in your ECM. Regardless, this is a serious problem, since your car could potentially fail to start when you’re stranded on a country road, in an empty parking lot, or any number of undesirable locations. 3. Sudden Loss of Gas Mileage
Why is my throttle position sensor not working?
The reason this happens is that the ECM doesn’t get correct information from the TPS as to how much to throttle the car. Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS.
Can a bad check engine light be a bad TPS?
The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling. This is often the first ever symptom of a bad TPS. Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component.
Why does my PCM fail every time I replace it?
PCMs typically fail for one of two reasons: voltage overloads (often due to a short in a solenoid or actuator circuit) or environmental factors (corrosion, thermal stress or vibration). If the shorted solenoid or actuator isn’t found and repaired, the voltage overload it creates may damage the replacement PCM, too.

What happens when a TPS sensor goes bad?
The data provided by TPS is invaluable for proper starting, idling, and easy throttle response. These operations are affected when a bad throttle position sensor feeds erroneous data to the car’s computer. Because of this, the following can occur: 1. Difficulty while changing gears.
