Code P0220 Chevrolet Description
The TP sensor is used to determine the throttle plate angle for various engine management systems. The Throttle Actuator Control (TAC) module provides the TP sensor with a 5-volt reference circuit and a low reference circuit. The TP sensor 1 signal voltage is low at closed throttle and increases as the throttle opens. When the PCM detects that the TP sensor 2 signal or TP sensor 5-volt reference voltage is outside the predetermined range, this Diagnostic Trouble Code (DTC) sets.
