Can a bad throttle position sensor cause a no start?
What happens when my throttle position sensor goes bad. 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 throttle body stop a car from starting?
