PROCEDURE

  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P11A9)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Trouble Codes.

    5. Check for DTCs.

  2. CHECK LUBRICATION SYSTEM

    1. Check the following items:

      1. Check the condition of the engine oil.

      2. Check for oil leaks. If an oil leak is found, repair or replace the malfunctioning part.

      3. Check the engine oil level. If the oil level is low, a DTC may have been stored.

      4. Check the engine oil pressure. If the oil pressure is low, the camshaft timing oil control valve assembly may not operate.

      5. Check the condition of the oil filter, oil pump assembly and oil paths.

      Tip:

      Check the items in the engine oil supply system which are related to operation of the camshaft timing gear assembly, such as the condition of the engine oil and operation of the oil pump assembly.

  3. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR INTAKE CAMSHAFT)

    1. Inspect the camshaft timing oil control valve assembly (for intake camshaft).

      Click here

      Tip:

      • Whether the camshaft timing oil control valve assembly is normal can be checked by interchanging the camshaft timing oil control valve assembly with that for the other camshaft and performing a simulation test.

      • Check for fine foreign matter.

      • When replacing the camshaft oil control valve assembly, replace the engine oil and oil filter at the same time to remove any foreign matter.

  6. CHECK WHETHER DTC OUTPUT RECURS (DTC P11A9)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Clear the DTCs.
