When idling can be continued
- Disconnect OCV connector.
- Warm up the engine and idle it.
- Apply battery voltage to the OCV and verify that the engine idles roughly or stalls.
- If the engine idles roughly or stalls, inspect the timing chain component (valve timing deviation).
- If the engine does not idle roughly or stalls, go to the next step.
- Remove the OCV and perform spool valve operation inspection. (See OIL CONTROL VALVE (OCV) INSPECTION
.)
- If not as specified, inspect the following:
- If as specified, inspect the following hydraulic passages for clogging or leakage or both:
- Oil pressure switch-OCV
- OCV-Camshaft
- Camshaft internal passage
- If they are normal, replace the camshaft pulley (with built-in variable valve timing actuator).
