SFI SYSTEM (w/o EGR System), Diagnostic DTC:P0016

DTC Code DTC Name
P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)

DESCRIPTION

In the VVT (Variable Valve Timing) system, the appropriate intake valve open and close timing is controlled by the ECM. The ECM performs intake valve control by performing the following: 1) controlling the camshaft and camshaft timing oil control valve assembly, and operating the camshaft timing gear assembly; and 2) changing the relative positions of the camshaft and crankshaft.

DTC No. DTC Detection Condition Trouble Area
P0016 Deviation in crankshaft position sensor signal and camshaft position sensor signal (2 trip detection logic).

  • Valve timing

  • Camshaft timing oil control valve assembly

  • Oil control valve filter

  • Camshaft timing gear assembly

  • ECM

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the tester on.

    4. Enter the following menus: Powertrain / Engine and ECT / DTC.

    5. Read the DTCs.

      Result
      Result Proceed to
      DTC P0016 is output A
      DTC P0016 and other DTCs are output B

      Tech Tips

      If any DTCs other than P0016 are output, troubleshoot those DTCs first.

  2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (CONTROL THE VVT LINEAR)

    Tech Tips

    If the VVT system can be operated through the Active Test, it can be assumed that the VVT system is operating normally.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the tester on.

    4. Put the engine in inspection mode (maintenance mode) Click here.

    5. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher.

    6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1) / All Data / VVT Change Angle #1.

    7. Perform the Active Test. Check that the displacement angle varies.

      OK
      Displacement angle varies.

      Tech Tips

      Test not possible with park (P) selected during charge control. Select neutral (N) to perform test.

    *2 Alignment Mark
    *3 No. 1 Cylinder at TDC Compression

    Tech Tips

    There are no marks on the cylinder head to match-up for the purpose of checking valve timing. Valve timing can only be inspected by lining up the colored plates on the timing chain with the marks on the pulleys. It may be necessary to remove and reinstall the chain to match-up the alignment marks Click here.

  4. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    1. Inspect the camshaft timing oil control valve assembly Click here.


    NG

    REPLACE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY Click here

    OK

  5. INSPECT OIL CONTROL VALVE FILTER


    1. A01J8US

      Remove the oil control valve filter Click here.

    2. Check that the filter is not clogged.

      OK
      Filter is not clogged.

    3. Reinstall the oil control valve filter Click here.


    NG

    REPLACE OIL CONTROL VALVE FILTER Click here

    OK

  6. REPLACE CAMSHAFT TIMING GEAR ASSEMBLY


    1. Replace the camshaft timing gear assembly Click here.


    NEXT

  7. CHECK WHETHER DTC OUTPUT RECURS (DTC P0016)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the tester on.

    4. Clear the DTCs Click here.

    5. Turn the power switch off and wait for at least 30 seconds.

    6. Turn the power switch on (IG).

    7. Turn the tester on.

    8. Put the engine in inspection mode (maintenance mode) Click here.

    9. Start the engine and warm it up.

    10. Allow the engine to idle for 5 minutes or more.

    11. Enter the following menus: Powertrain / Engine and ECT / DTC / Pending.

    12. Read the pending DTCs.
