When idling can be continued
If simulation function of M-MDS is used:
- Warm up the engine to normal operating temperature.
- Verify that the DTC P2088:00 or P2089:00 are shown. (See
ON-BOARD DIAGNOSTIC TEST
).
- If the DTC P2088:00 or P2089:00 are shown, perform the DTC inspection. (See DTC P2088:00 ). (See DTC P2089:00 ).
- Start the engine and run it is idling.
- Access the VT Duty1 wt PID simulation function using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST ).
- Increase the OCV duty value and verify that the engine idles roughly or stalls.
- If as specified, inspect the timing belt component (valve timing deviation).
- If not as specified, go to the next step.
- Remove the OCV while the connector is connected. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION ).
- Switch the ignition to ON (engine off).
- Access the VT Duty1 wt PID simulation function using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST ).
- Increase the OCV duty value and verify that the spool valve operates in the advance direction.
- If as specified, inspect the following hydraulic passage for restriction and/or leakage.
- Oil pressure switch-OCV
- OCV-Camshaft
- Camshaft internal passage
- If not as specified, inspect the following:
- OCV operation (See OIL CONTROL VALVE (OCV) INSPECTION ).
- If as specified, inspect the following hydraulic passage for restriction and/or leakage.
- If they are normal, replace the intake camshaft pulley (with a built-into variable valve timing actuator). (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION ).
If simulation function of M-MDS is not used:
- Disconnect the OCV connector.
- Verify that the DTC P2088:00 or P2089:00 are shown. (See
ON-BOARD DIAGNOSTIC TEST
).
- If the DTC P2088:00 or P2089:00 are shown, perform the DTC inspection. (See DTC P2088:00 ). (See DTC P2089:00 ).
- 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 belt component (valve timing deviation).
- If the engine does not idle roughly or stalls, go to the next step.
- Remove the OCV and perform the spool valve operation inspection. (See
OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION
).
- 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 not as specified, inspect the following:
- If they are normal, replace the camshaft pulley (with built-into variable valve timing actuator). (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION ).
