SFI SYSTEM, Diagnostic DTC:P000A,P0011 and P0012

DTC Code DTC Name
P000A A Camshaft Position Slow Response Bank 1
P0011 A Camshaft Position - Timing Over-Advanced or System Performance Bank 1
P0012 A Camshaft Position - Timing Over-Retarded Bank 1

DESCRIPTION

The variable valve timing system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the camshaft timing gear assembly to adjust the valve timing.

DTC No.

P0011

A Camshaft Position - Timing Over-Advanced or System Performance Bank 1

Camshaft timing gear assembly is stuck.

  • Camshaft timing gear assembly

  • Camshaft timing oil control valve assembly (for intake camshaft)

  • Wire harness or connector

  • ECM

P0012

A Camshaft Position - Timing Over-Retarded Bank 1

Camshaft timing gear assembly is stuck or control* for cleaning camshaft timing oil control valve assembly cannot be performed.

(*: Control that forcibly activates camshaft timing oil control valve assembly to remove foreign matter.)

  • Camshaft timing gear assembly

MONITOR DESCRIPTION

These DTCs are stored when a malfunction is detected in the variable valve timing system (for intake camshaft). If the change in actual valve timing is small and the difference between target valve timing and actual valve timing is large, the ECM will determine that the camshaft timing gear assembly is stuck, illuminate the MIL and store a DTC.

PROCEDURE

  1. CHECK ANY OTHER DTC OUTPUT (IN ADDITION TO DTC P000A, P0011 AND/OR P0012)

    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.

  4. CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR INTAKE CAMSHAFT) - ECM)

    1. Disconnect the camshaft timing oil control valve assembly (for intake and exhaust camshaft) connectors.

    2. Disconnect the ECM connector.

    3. Measure the resistance according to the value(s) in the table below.
