This sensors output, along with those of other sensors, is sent to the engine control module, which determines the quantity of fuel to inject into your vehicles engine. In this scenario, the first method of testing the throttle position sensor is to use voltage. The engine control module (ECM) learns the idle position of the throttle plate to ensure the cor- rect idle. Heat the vehiclesengine to the proper operating temperature before proceeding with the rest of the procedure. If the throttle body is failing, then the car might struggle to speed up when the accelerator pedal is pressed or, on the other hand, may suddenly go very fast long after the driver has floored the gas pedal.
