TPS Sensors

The throttle position sensor in your vehicle is a vital part of your EFI system. This sensor sends voltage to the computer to indicate throttle angle. The engine computer delivers fuel to your engine based on this signal. When your TPS sensor goes bad your engine will run poorly and performance will suffer. 

If you aren't sure about your TPS sensor, check our guides at My Pro Street to learn more about the throttle position sensor and how to check it. 

With a bad TPS sensor your vehicle could experience lack of power, inconsistent transmission shift points, rich or lean running, spark plug fouling, poor fuel economy, or even catalytic converter failure.
