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 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 they are normal, replace the camshaft pulley (with built-into variable valve timing actuator). (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION .)
