Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. CHECK FOR AN ACTIVE DTC 
    NOTE:

    Perform any Service Bulletins or Star Cases relating to this fault before continuing with this test procedure.

    NOTE:

    Diagnose and repair any Camshaft Oil Control Valve Circuit or Slow Response DTCs before continuing with this diagnostic test.

    NOTE:

    If a Cam Phaser or Camshaft Oil Control Valve is stuck, there may also be a Camshaft Position Slow Response and/or Multiple Cylinder Misfire DTC present.

    1. Turn the ignition on.
    2. With the scan tool, read DTCs and record on the repair order.
    3. Record the related Freeze Frame data.
    4. With the scan tool, erase DTCs.
    5. Start the engine and allow it to idle. It maybe necessary to tests drive the vehicle and allow cam phasing to occur in order to reset the fault.
      WARNING:

      When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

    6. With the scan tool, read DTCs.

      Is the DTC active or pending?

      Yes, for vehicles without Variable Cam Timing 

      • Go To  3

      Yes, for vehicles with Variable Cam Timing 

      • Go To  2

      No 

  2. CAMSHAFT POSITION SOLENOID CLEANING 
    1. With the scan tool perform the Exhaust Phaser 1 Cleaning function.
    2. With the scan tool, erase DTCs.
    3. Start the engine and allow it to idle. It maybe necessary to tests drive the vehicle and allow cam phasing to occur in order to reset the fault.
    4. With the scan tool read DTCs.

      Did the DTC return?

      Yes 

      • Go To  3

      No 

  3. ENGINE OIL/ENGINE MECHANICAL 
    NOTE:

    The following items should be checked before continuing with this procedure. Failure to do so may lead to misdiagnosis.

    • ENGINE MECHANICAL TOLERANCES OUT OF SPECIFICATION
    • ENGINE OIL PRESSURE OUT OF SPECIFICATION
    • LOW ENGINE OIL LEVEL
    • INCORRECT ENGINE OIL FILTER (DOES NOT MEET OEM SPECIFICATIONS)
    • DETERIORATED OR DIRTY OIL
    • CONTAMINATED ENGINE OIL
    • INCORRECT ENGINE OIL VISCOSITY
    • AERATED ENGINE OIL

    1. If any of the above conditions are found, repair as necessary.

      Were any of the above conditions present?

      Yes 

      • Repair the engine oiling or mechanical condition (i.e. improper oil drain back, oil sludge, damaged oil pump, pick-up tube or seal, etc.).
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  4
  4. CHECK THE CAM PHASER OPERATION 
    NOTE:

    It may be necessary to drive the vehicle to allow the Cam Phaser to operate normally and then return to lock pin at idle. The purpose is to check for a phaser that may not be responding quick enough and causing this DTC. The phaser may not

    1. With the scan tool, monitor and compare the Camshaft Position Sensor desired  position value with the Camshaft Position Sensor actual  position value with the engine running at idle. After comparing the two values at idle, check and compare the values at several different engine speeds. The best way to do this is to raise the engine speed quickly and hold steady for up to 30 seconds and monitor the actual and desired values. Then lower the engine speed and hold steady at a level above idle (off of lock pin) for up to 30 seconds and monitor the actual and desired values. Repeat this a few times up and down monitoring the values and then allow the engine to come back to idle and monitor the actual position to verify that the phaser is coming back to lock pin position.
      NOTE:

      The purpose of this step is to determine if the Cam Phaser or Oil Control Valve is binding or dragging due to a mechanical or oiling system issue. We are looking for the actual position to respond and quickly mirror the desired position, not necessarily for it to achieve the desired position.

      Is the actual Cam Phaser position changing quickly and mirroring the desired Cam Phaser position?

      Yes 

      • Check for proper alignment of the timing chain and sprockets in accordance with the Service Information. Also check the Timing Chain Tensioner and Guide for faulty or broken components. Perform the appropriate repair in accordance with the Service Information. The "Cam/Crank Relearn" Procedure  must be performed every time there has been a repair/replacement made to a CMP Sensor and/or CKP Sensor, flywheel, valvetrain, timing chain or gears. Failure to do so can cause a misfire fault to set. With the scan tool, perform the "Cam/Crank Relearn" Procedure.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  5
  5. CHECK THE ENGINE OIL PRESSURE AND ENGINE MECHANICAL CONDITION 
    1. Turn the engine off.
    2. Install an oil pressure gauge on the engine.
    3. Start the engine and allow it to idle.
    4. Monitor the engine oil pressure reading on the gauge.

      Is the oil pressure reading steady and above the engine specifications?

      Yes 

      • Go To  6

      No 

      • Repair the engine oiling or mechanical condition (i.e. low engine oil, incorrect engine oil viscosity, contaminated or deteriorating engine oil, improper oil drain back or blocked screen in cylinder head, oil sludge, damaged oil pump, pick-up tube or seal, incorrect engine oil filter (DOES NOT MEET OEM SPECIFICATIONS) etc.).
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  6. CHECK THE CAMSHAFT OIL CONTROL VALVE OPERATION 
    1. Turn the ignition off.
    2. Disconnect the Camshaft Oil Control Valve harness connector.
    3. Remove the Camshaft Oil Control Valve.
    4. Reconnect the Camshaft Oil Control Valve harness connector.
    5. Turn the ignition on.
    6. With the scan tool, actuate the Camshaft Oil Control Valve on and off several times.

      Does the Camshaft Oil Control Valve move freely during actuation?

      Yes 

      • Go To  7

      No 

      • Replace the Camshaft Oil Control Valve in accordance with the Service Information.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  7. CHECK THE ENGINE TIMING ALIGNMENT 
    1. Check for proper alignment of the timing chain and sprocket in accordance with the Service Information. Also check the Cam Sensor Target Wheel, Timing Chain Tensioner and Guide for faulty or broken components.

      Were any issue found with the timing alignment or components?

      Yes 

      • Perform the appropriate repair in accordance with the Service Information. The "Cam/Crank Relearn" Procedure  must be performed every time there has been a repair/replacement made to a CMP Sensor and/or CKP Sensor, flywheel, valvetrain, timing chain or gears. Failure to do so can cause a misfire fault to set. With the scan tool, perform the "Cam/Crank Relearn" Procedure.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • The failure is caused by a lack of oil pressure in the Cylinder Head or a faulty Cam Phaser assembly. Perform the appropriate repair in accordance with the Service Information. The "Cam/Crank Relearn" Procedure  must be performed every time there has been a repair/replacement made to a CMP Sensor and/or CKP Sensor, Flywheel, valvetrain, timing chain or gears. Failure to do so can cause a misfire fault to set. With the scan tool, perform the "Cam/Crank Relearn" Procedure.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
