Details On DTCs

DESCRIPTION

Electric variable valve timing control system:

P0011:00: Over-advanced
P0012:00: Over-retarded

DETECTION CONDITION

Determination conditions

P0011:00: For the advance amount from the maximum intake valve retard position, a condition in which the actual advance amount is larger than the target value continues for a specified period of time.

P0012:00: For the advance amount from the maximum intake valve retard position, a condition in which the actual advance amount is smaller than the target value continues for a specified period of time.

POSSIBLE CAUSE

Electric variable valve timing motor/driver connectors or terminals 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
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
PCM connector or terminals malfunction
Electric variable valve timing relay malfunction
Electric variable valve timing motor malfunction
Electric variable valve timing actuator malfunction
- Electric variable valve timing actuator is stuck in advanced position
  - Electric variable valve timing actuator is stuck in retarded position
Timing chain malfunction
- Poor assembly of timing chain
  - Looseness or jumping
Mis-detection of intake CMP sensor
Mis-detection of CKP sensor
PCM malfunction
