DTC P2112-00: Throttle Valve Actuator Motor Current Range/Performance Problem: Notes

DTC P2112-00: (PCM, VIN M) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P2112-00:	Throttle valve actuator motor current range/performance problem
DETECTION CONDITION	The throttle valve actuator control duty ratio is 95 % or more with the ignition switched ON (engine on). Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Restricts the upper limit of the engine speed. Stops the drive-by-wire control (throttle valve is open at approx. 8 ° by return spring force).
POSSIBLE CAUSE	Throttle body connector or terminals malfunction PCM connector or terminals malfunction Open circuit in wiring harness between the following terminals: Throttle body terminal E-PCM terminal 1CQ Throttle body terminal F-PCM terminal 1CR Throttle valve malfunction Throttle valve actuator malfunction PCM malfunction Throttle valve actuator control module malfunction (built-into PCM)
