Intention of troubleshooting procedure
- Step 1-5
- Perform an inspection of the connectors and wiring harnesses between the battery positive terminal and electric variable valve timing relay and the electric variable valve timing motor/driver.
- Step 6
- Perform a unit inspection of the electric variable valve timing relay.
- Step 7-9
- Perform an inspection of the electric variable valve timing drive parts.
- Step 10-11
- Inspect the intake CMP sensor and CKP sensor detection areas for adhesion of foreign matter.
- Step 12-13
- Verify that the primary malfunction is resolved and there are no other malfunctions.
| STEP | INSPECTION | RESULTS | ACTION |
|---|---|---|---|
