Code P1120 Description

The Throttle Position Sensor (TPS) responds to the accelerator pedal movement. The TPS is a rotary potentiometer sensor that provides a signal to the Powertrain Control Module (PCM) that is linearly proportional to the throttle plate/shaft position. As the TPS is rotated by the throttle shaft, the following operating conditions are determined by the PCM:
• Closed throttle (includes idle or deceleration)
• Part throttle (includes cruise or moderate acceleration)
• Wide open throttle (includes maximum acceleration or de-choke on crank)
• Throttle angle rate
