DTC P0010: Camshaft Position "A" Actuator Circuit (Bank 1); DTC P0020: Camshaft Position "A" Actuator Circuit (Bank 2): Procedure

WARNING: This page is about a different variant/trim than selected.
  1. PERFORM ACTIVE TEST USING TECHSTREAM (OPERATE OIL CONTROL VALVE FOR INTAKE CAMSHAFT) 
    1. Connect the Techstream to the DLC3.
    2. Start the engine and turn the tester on.
    3. Warm up the engine.
    4. Select the following menu items: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1) or Control the VVT Linear (Bank 2).
    5. Check the engine speed while operating the oil control valve using the tester.

      OK

      Tester Operation Specified Condition
      0% Normal engine speed
      100% Engine idles roughly or stalls (soon after OCV switched from OFF to ON)

    NG → See step   2 

    OK → See step   5 

  2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR INTAKE CAMSHAFT) 
    1. Disconnect the intake camshaft timing oil control valve connector.

    3. Reconnect the camshaft timing oil control valve connector.

    NG → See step   6 

    OK: Go to next step 

  3. CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE - ECM) 
    1. Disconnect the intake camshaft timing camshaft oil control valve connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance (Check for open)

      Bank 1 

      Bank 2 

      Tester Connection Condition Specified Condition
      B50-19 (OC1+) - B24-1 Always Below 1 Ω
      B50-20 (OC1-) - B24-2 Always Below 1 Ω
      Tester Connection Condition Specified Condition
      B51-19 (OC2+) - B25-1 Always Below 1 Ω
      B51-20 (OC2-) - B25-2 Always Below 1 Ω

      Standard resistance (Check for short)

      Bank 1 

      Bank 2 

      Tester Connection Condition Specified Condition
      B50-19 (OC1+) or B24-1 - Body ground Always 10 kΩ or higher

      Tester Connection Condition Specified Condition
      B51-19 (OC2+) or B25-1 - Body ground Always 10 kΩ or higher
      B51-20 (OC2-) or B25-2 - Body ground Always 10 kΩ or higher
    4. Reconnect the camshaft timing oil control valve connector.
    5. Reconnect the ECM connector.

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE - ECM) 

    OK → See step   4 

  4. REPLACE ECM. Refer to  COMPONENTS 
  5. CHECK FOR INTERMITTENT PROBLEMS. Refer to  CHECK FOR INTERMITTENT PROBLEMS 
  6. REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY. Refer to  REMOVAL
