P1221 Fault Code: Understanding The Causes And Solutions
The P1221 fault code refers to a problem with the Throttle Position (TP) Sensor in the Throttle Actuator Control (TAC) assembly. This sensor consists of two individual throttle position sensors housed together. It uses two separate signal circuits, a low reference circuit, and a 5-volt reference circuit to connect to the TAC module.
As the throttle opens, the TP sensor signal voltage increases. The signal circuit for the TP sensor is pulled up to a 5-volt reference voltage.
The P1221 code specifically indicates a correlation issue between Throttle Position Sensor 1 and Throttle Position Sensor 2.
