DTC P2101:00

Throttle valve actuator control motor circuit range/performance problem

DETECTION CONDITION

•  The PCM turns the main relay on, but if the input voltage is 6.0 V or less, then the PCM determines that the main relay control circuit voltage is low.

•  There is a system error in the electrical throttle control system of the PCM.

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 (Mode 2)/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

•  Short to ground or open circuit in main relay power supply circuit:

―  MAIN 200 A fuse and/or ENG.MAIN 40 A fuse malfunction

•  ENGINE2 15 A fuse malfunction

•  Short to ground in wiring harness between the following terminals:

―  Main relay terminal D—PCM terminal 1CK
