Toyota 89452-06020 Sensor, Throttle Position

The Throttle Position Sensor TPS was integrated into the throttle body in the 2007 and following models and consequently should the TPS fail then the throttle body would require replacement. h, The TPS is located on the end of the throttle shaft on the throttle body and the PCM can measure its output voltage to regulate fuel delivery in proportion to the driver's demand as indicated by the throttle valve angle. A bad or poorly grounded TPS can cause surges of fuel from the injectors and poor idle as the PCM may misread changes in the throttle. Problems with the TPS circuits will set a diagnostic trouble code. For this, ensure that the ignition key is off, and remove the electrical connector in contact with the TPS, unscrew and loosen the TPS screws fixed on the throttle body and then remove the TPS. reinstallation is the process of putting back again equipment, and just as much as the process of removal has steps, installation has the steps in the opposite order.

Problems with the TPS or motor can lead to intermittent bursts of fuel from the injectors and an unstable idle, as the Powertrain Control Module (PCM) may incorrectly interpret that the throttle is moving.

The Throttle Position Sensor (TPS) is a component that monitors the output voltage to determine fuel delivery based on throttle valve angle. It is located on the end of the throttle shaft on the throttle body.
