DTC P2101:00: Notes

DTC P2101:00	Throttle valve actuator power supply circuit problem
DETECTION CONDITION	The PCM turns the main relay on, but the input voltage is 5.0 V or less , then the PCM determines that the main relay control circuit voltage is low. The PCM monitors the input voltage from the main relay. The PCM turns the main relay off, but the input voltage is 5.0 V or more , then the PCM determines that the main relay control circuit voltage is high. Diagnostic support note This is a continuous monitor (CCM). The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	PCM connector or terminals malfunction Main relay malfunction Short to ground or open circuit in main relay power supply circuit Short to ground in wiring harness between the following terminals: MAIN 200 A fuse-Main relay terminal C EGI 10 A fuse-Main relay terminal A MAIN 200 A fuse and/or EGI 10 A fuse malfunction Open circuit in wiring harness between the following terminals: Battery positive terminal-Main relay terminal C Battery positive terminal-Main relay terminal A Short to ground or open circuit in main relay control circuit: Short to ground in wiring harness between the following terminals: ENG INJ 15 A fuse-PCM terminal 1BF ENG INJ 15 A fuse-PCM terminal 1BE Main relay terminal B-PCM terminal 1AJ ENG INJ 15 A fuse malfunction Open circuit in wiring harness between the following terminals: Main relay terminal D-PCM terminal 1BF Main relay terminal D-PCM terminal 1BE Main relay terminal B-PCM terminal 1AJ Short to power supply in wiring harness between the following terminals: Main relay terminal D-PCM terminal 1BF Main relay terminal D-PCM terminal 1BE Main relay terminal B-PCM terminal 1AJ TP sensor No.1 and related circuit malfunction TP sensor No.2 and related circuit malfunction PCM malfunction
