When idling can be continued

Disconnect the OCV connector. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION .)
Warm up the engine and idle it.
Apply the battery voltage to the OCV and verify that the engine idles rough or stalls.
- If the engine idles rough or stalls, inspect the timing chain component (valve timing deviation). (See HYDRAULIC VARIABLE VALVE TIMING ACTUATOR INSPECTION .)
- If the engine does not idle rough or stalls, go to the next step.
Remove the OCV and perform the Spool Valve Operation Inspection. (See OIL CONTROL VALVE (OCV) INSPECTION .)
- If not as specified, inspect the following:
  - OCV (See OIL CONTROL VALVE (OCV) INSPECTION .)
  - Harnesses and connectors between OCV and PCM have an open or short circuit
- If as specified, inspect the following hydraulic passages for restriction or leakage or both:
- Oil pressure switch-OCV
- OCV-Camshaft
- Camshaft internal passage
If they are normal, replace the hydraulic variable valve timing actuator. (See ELECTRIC VARIABLE VALVE TIMING ACTUATOR, HYDRAULIC VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION .)
