Circuit / System Description
The throttle body assembly contains 2?throttle position (TP) sensors. The TP sensors are mounted to the throttle body assembly and are not serviceable. The TP sensors provide a signal voltage that changes relative to throttle blade angle. The engine control module (ECM) supplies the TP sensors with a common 5-volt reference circuit, a common low reference circuit, and 2?independent signal circuits.
The TP sensors have opposite functionality. TP sensor?1 signal voltage decreases from above 4?volts at idle to below 1?volt at wide open throttle (WOT). TP sensor?2 signal voltage increases from below 1?volt at idle to above 4?volts at WOT.
The ECM compares the signal of the TP?sensor?1 and TP?sensor?2 through the entire range. If the ECM detects a predetermined difference between sensor?1 and sensor?2, or a predetermined difference from the predicted range, this DTC sets.
