What is the Throttle Position Sensor (TPS) and how does it work for Chevrolet Colorado and GMC Canyon?

The TPS is a potentiometer linked to the end of the throttle shaft in the throttle body. The PCM uses this TPS output voltage to determine fuel delivery versus throttle valve angle. The Throttle Actuator Control system (TAC) works with the TPS and APP sensors. They actually are two sensors located in one housing. Diagnostic Trouble Codes (DTCs) are set when there is a disparity between the actual throttle position and that which is sensed by the TPS unit. It is necessary to replace a whole throttle body when its TPS acts up.

GMC Canyon Throttle Position Sensor

The Throttle Position Sensor (TPS) used in GMC Canyon is very important in the regulation of the air-fuel mixture for proper combustion. The Throttle Position Sensor calculates the position of the gland to send signals of the engine throughout the power production, thus adjusting the fuel injection system. This feedback is done repeatedly within a second to enable accurate acceleration, speed maintenance, as well as near perfect deceleration. For years GMC Canyon has used different Throttle Position Sensor types: contactless with Hall effect, inductive or magnetoresistive ones. Unlike most modern sensors which are potentiometric types which work on contact and change in resistance. Non-contact Throttle Position Sensor improves reliability and performance since they measure changes in the magnetic field and does not depend on wear out from moving mechanisms. Their connections with accelerator pedal sensors moreover enhance the GMC Canyon vehicle's electronic throttle control system and therefore the performance of these vehicles.

Each OEM GMC Canyon Throttle Position Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
