What Does P2112 Code Mean?

    OBD-II Code P2112 is defined as a Throttle Actuator Control System - Stuck Closed

    The throttle motor opens and closes the throttle plate, allowing more or less air to flow through the engine based on the driver's request for power. The throttle motor is controlled by the engine computer (PCM). If the PCM does any movement from the throttle motor, code P2112 will set. The PCM may also put the engine into "limp home mode", limiting the available power from the engine to prevent unwanted acceleration.

    P2112 Symptoms

    • Decreased engine performance
    • Engine may enter limp home mode (reduced performance)

    Common Problems That Trigger the P2112 Code

    • Powertrain Control Module (PCM) failure
    • Throttle body assembly failure
    • Throttle control motor failure
    • Wiring issue
