DTC P2101-00; Throttle Valve Actuator Control Motor Circuit Range/Performance Problem: Notes

DETECTION CONDITION AND POSSIBLE CAUSE

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/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 C-PCM terminal 1CK Main relay terminal C-PCM terminal 2S Main relay terminal E-PCM terminal 2K PCM connector or terminals malfunction Open circuit in wiring harness between the following terminals: Main relay terminal C-PCM terminal 1CK Main relay terminal C-PCM terminal 2S Main relay terminal E-PCM terminal 2K Throttle valve actuator and/or related circuit malfunction Throttle valve actuator malfunction PCM malfunction
