The Delphi Throttle Position Sensor is a top-class component that can accurately send information to your engine management computer. A throttle position sensor, shortly known as the TP sensor or TPS, monitors the position of the throttle in an internal combustion chamber. As the throttle opens wider, the TPS changes resistance. Such information is actually what the engine computer needs to adjust the mixture of air and fuel in the car. This information sent by the TPS is also important for the engine to start up and idle properly, and for the vehicle to have smooth throttle response. An electro-mechanical moving part, the TPS can be adjusted. However, it's best to let a qualified auto mechanic to do the job. Even so, your ride's TPS can anytime malfunction and eventually wear out. This is because improper service procedures to engine systems take toll on the throttle position sensor in due course.
