DTC P0010-00: Electric Variable Valve Timing Control Problem: Notes

DTC DETECTION DESCRIPTION

DTC P0010:00	Electric variable valve timing control circuit range/performance problem
DETECTION CONDITION	Any one of the following conditions is met: A malfunction is detected in the results of the on-board diagnostic test received from the electric variable valve timing driver. The motor speed signal received from the electric variable valve timing driver is in error. 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	Stops activation of the electric variable valve timing driver.
POSSIBLE CAUSE	Electric variable valve timing motor/driver connectors or terminals malfunction Electric variable valve timing relay malfunction Short to ground or open circuit in electric variable valve timing relay power supply circuit Short to ground in wiring harness between MAIN 200 A fuse and electric variable valve timing relay terminal D MAIN 200 A fuse and/or EVVT 20 A fuse malfunction Open circuit in wiring harness between battery positive terminal and electric variable valve timing relay terminal D Short to ground in wiring harness between the following terminals: Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 1E Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 2B Short to power supply in wiring harness between the following terminals: Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 1E Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 2B Open circuit in wiring harness between the following terminals: Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 1E Electric variable valve timing relay terminal C-Electric variable valve timing motor/driver terminal 2B Open circuit in wiring harness between electric variable valve timing motor/driver terminal 2A and body ground Short to ground in wiring harness between the following terminals: Electric variable valve timing motor/driver terminal 1D-PCM terminal 1AZ Electric variable valve timing motor/driver terminal 1C-PCM terminal 1O Electric variable valve timing motor/driver terminal 1B-PCM terminal 1J Electric variable valve timing motor/driver terminal 1A-PCM terminal 1AE PCM connector or terminals malfunction Short to power supply in wiring harness between the following terminals: Electric variable valve timing motor/driver terminal 1D-PCM terminal 1AZ Electric variable valve timing motor/driver terminal 1C-PCM terminal 1O Electric variable valve timing motor/driver terminal 1B-PCM terminal 1J Electric variable valve timing motor/driver terminal 1A-PCM terminal 1AE Electric variable valve timing motor/driver circuits are shorted to each other Open circuit in wiring harness between the following terminals: Electric variable valve timing motor/driver terminal 1D-PCM terminal 1AZ Electric variable valve timing motor/driver terminal 1C-PCM terminal 1O Electric variable valve timing motor/driver terminal 1B-PCM terminal 1J Electric variable valve timing motor/driver terminal 1A-PCM terminal 1AE Electric variable valve timing driver malfunction Electric variable valve timing motor malfunction PCM malfunction
