Throttle position sensors are switches on the throttle body that keep the engine control computer informed about the throttle opening. The TPS is a variable resistor that changes resistance as the throttle opens wider. The computer needs this information to change the air/fuel mixture. The TPS requires a very critical adjustment procedure in order to send the proper signal to the computer for optimum performance. If your TPS needs replacing, we have the part you need!
