Circuit / System Description
The throttle position (TP) sensors?1 and 2 are located within the throttle body assembly. The TP sensors share a common 5-volt reference circuit and a common low reference circuit. The 5-volt reference circuit is also shared with the accelerator pedal position (APP) sensor?2. The 5-volt reference voltage is supplied on 2?separate engine control module (ECM) terminals, but the terminals are connected internally to the same voltage supply. Each TP sensor has an individual signal circuit, which provides the ECM with a signal voltage proportional to throttle the plate movement. When the throttle plate is in the closed position, the TP sensor?1 signal voltage is near the low reference and increases as the throttle plate is opened. The TP sensor?2 signal voltage at closed throttle is near the 5-volt reference and decreases as the throttle plate is opened. If the ECM detects that the TP sensors are not within a predicted value from each other, DTC?P2135 sets.
