DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P1380:00 |
Electric variable valve timing control circuit problem |
| DETECTION CONDITION |
- A malfunction is detected in the results of the on-board diagnostic test received from electric variable valve timing driver.
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.
- The 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
- Short to ground in wiring harness between electric variable valve timing motor/driver terminal 1A and PCM terminal 1AE
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between electric variable valve timing motor/driver terminal 1A and PCM terminal 1AE
