P0220 Cadillac Code - Throttle Position Sensor 2 Circuit
Quick Answer
The Throttle Position (TP) sensor 2 is a potentiometer type sensor with 3 circuits: A 5-volt reference circuit, a low reference circuit, and a signal circuit. Common causes include Faulty Throttle Position Sensor (TPS), Throttle Position Sensor (TPS) harness is open or shorted, Throttle Position Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0220 Cadillac 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.
