SFI SYSTEM, Diagnostic DTC:P0013, P0023

DTC Code DTC Name
P0013 Camshaft Position "B" Actuator Circuit / Open (Bank 1)
P0023 Camshaft Position "B" Actuator Circuit / Open (Bank 2)

DESCRIPTION

This DTC is designed to detect opens or shorts in the camshaft oil control valve circuit. If the oil control valve's duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and set the DTC.

The Variable Valve Timing (VVT) system adjusts the exhaust valve timing to improve the driveability. The engine oil pressure turns the camshaft actuator to adjust the valve timing. The oil control valve is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies the 12 volts to the solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.

INSPECTION PROCEDURE

Tech Tips


  • If DTC P0013 is displayed, check the bank 1 VVT system for exhaust side circuit.

  • Bank 1 refers to the bank that includes No. 1 cylinder.

  • If DTC P0023 is displayed, check the bank 2 VVT system for exhaust side circuit.

  • Bank 2 refers to the bank that does not include No. 1 cylinder.

  • Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK DTC (DTC P0013 OR P0023)


    1. Connect the intelligent tester to the DLC3.

    2. Clear the DTC after recording the freeze frame data and DTC.

    3. Turn the engine switch off.

    4. Allow the engine to idle and check the DTC.

    5. Check that P0013 or P0023 is output.

      Remove the oil control valve Click here.

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

      Standard Resistance
      Tester Connections Condition Specified Conditions
      1 - 2 20°C (68°F) 6.9 to 7.9 Ω
    3. A01606KE10

      Apply the positive battery voltage to terminal 1 and negative battery voltage to terminal 2. Check the valve operation.

      OK
      Valve moves quickly.

    4. Reinstall the oil control valve.
