SFI SYSTEM(w/ Secondary Air Injection System), Diagnostic DTC:P0010, P0020

DTC Code DTC Name
P0010 Camshaft Position "A" Actuator Circuit (Bank 1)
P0020 Camshaft Position "A" Actuator Circuit (Bank 2)

DESCRIPTION


B001VOYE07
DTC Code DTC Detection Condition Trouble Area
P0010 An open or short in the Camshaft Oil Control Valve (OCV) for intake side (for Bank 1) circuit (1 trip detection logic).
  • Open or short in Camshaft Oil Control Valve (OCV) (for intake side of Bank 1) circuit

  • OCV (for intake side of Bank 1)

  • ECM

P0020 An open or short in the OCV for intake side (for Bank 2) circuit (1 trip detection logic).
  • Open or short in OCV (for intake side of Bank 2) circuit

  • OCV (for intake side of Bank 2)

  • ECM

Tech Tips

This DTC relates to the Camshaft Oil Control Valve (OCV).

MONITOR DESCRIPTION

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

Tech Tips


  • 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.

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

    *: The No. 1 cylinder is the cylinder which is farthest from the transmission.

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

PROCEDURE


  1. CHECK DTC


    1. Clear DTC after recording the freeze frame data and DTC Click here.

    2. Turn the engine switch off.

    3. Allow the engine to idle and check DTC.

    4. Check that P0010 or P0020 is not output.

      OK
      P0010 or P0020 is not output.

    OK
    NG
  2. INSPECT CAMSHAFT OIL CONTROL VALVE ASSEMBLY


    1. B001YVLE02
      *1 Component without harness connected: (Oil Control Valve)

      Disconnect the C27 or C28 camshaft oil control valve (OCV) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 6.9 to 7.9 Ω

    NG
    OK
  3. CHECK HARNESS AND CONNECTOR (OCV - ECM)


    1. Disconnect the C27 or C28 OCV connector.

    2. Disconnect the C45 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C27-1 - C45-6 (OC1+) Always Below 1 Ω
      C28-1 - C45-4 (OC2+) Always Below 1 Ω
      C27-2 - C45-5 (OC1-) Always Below 1 Ω
      C28-2 - C45-3 (OC2-) Always Below 1 Ω
      C27-1 or C45-6 (OC1+) - Body ground Always 10 kΩ or higher
      C28-1 or C45-4 (OC2+) - Body ground Always 10 kΩ or higher
      C27-2 or C45-5 (OC1-) - Body ground Always 10 kΩ or higher
      C28-2 or C45-3 (OC2-) - Body ground Always 10 kΩ or higher

    OK
    NG
