Is the TPS part of the transmission?

Is the throttle position sensor part of the transmission or the engine?

    NO it is not. However the TPS does play a part on when the transmission shift's because the TPS basically tell's the computer how far down you are pushing on the accelerator pedal.

    TPS = Throttle Position Sensor. Mounts on the throttle shaft of the throttle body on most fuel injected cars and some late model electronic carburetor vehicles as well. Early vehicles had a simple switch that told the Engine Control Module (ECM) that the throttle was either fully closed or fully open. Later, more sophisticated cars used a TPS that tells the ECM the exact percentage of throttle opening from 0% to 100%. The TPS works with the ECM and controls a host of related functions including up and downshift points for an electronic transmission controlled vehicle.

    Both - and neither!

    Both in the fact that the TPS is the sensor that sends the position information to the PCM/ECM as part of the feedback mechanism to control both fuel delivery and shift points for the transmission.

    Neither in the sense that it is a sensor - and technically part of the engine/trans management system.

    The one post is correct in that it is integrated into the throttle body - normally considered an engine component.

  • to an extent it can be, in the event of a computer controlled transmission, the CPU looks at the TPS for throttle position for a load indicator along with other sensors. that tps is not bolted to the trans but it still is part of the systems that control it.

    The (TPS) & the (IA) idle air control solenoid are both mounted side by side into the side of the throttle body,they have two bolts that holds each one of them into place ,theres also a wire plug going to each of them. Your check engine light should be on if one of these sensors are bad ,it will als make your transmission jerk when it shifts into gear.

    That's a tricky question in the sense that it is mechanically part of the engine (located on the throttle body) but electronically, its data plays a big part in the shifting of the transmission.

    It plays a key roll on both.it is part of the engine and relays info to the transmission

    CPS (clutch position sensor) maybe but not the TPS. TPS is a powertrain part.

    it is part of the throttle body which is located on top of the engine. youll find it if you follow the air filter.
