The TP sensors are used to determine the throttle plate angle for various engine management systems. The PCM provides each TP sensor a 5-volt reference circuit and a low reference circuit. The TP sensors then provide the PCM with signal voltage proportional to throttle plate movement. Both TP sensor signal voltages are low at closed throttle and increase as the throttle opens. When the PCM detects that TP sensor 1 signal and TP sensor 2 signals disagree or signal voltages are outside the predetermined range, this DTC sets.
