P0018 Deviations in crankshaft position sensor and VVT sensor (for intake camshaft, bank 2) signals (2 trip detection logic)

INSPECTION PROCEDURE

Tech Tips


  • 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.

  • 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016 OR P0018)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch on (IG) and turn the tester on.

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

    4. Read the DTCs.

      Result
      Display (DTC Output) Proceed to
      P0016 or P0018 A
      P0016 or P0018 and other DTCs B

      Tech Tips

      If any DTCs other than P0016 or P0018 are output, troubleshoot those DTCs first.

  2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE OIL CONTROL VALVE FOR INTAKE CAMSHAFT)


    1. Connect the intelligent tester to the DLC3.

    2. Start the engine and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1) or Control the VVT Linear (Bank 2).

    4. Check the engine speed while operating the camshaft timing oil control valve assembly using the tester.

      OK
      Tester Operation Specified Condition
      0% Normal engine idle speed
      100% Engine idles roughly or stalls

    OK

  3. CHECK WHETHER DTC OUTPUT RECURS (DTC P0016 OR P0018)


    1. Connect the intelligent tester to the DLC 3.

    2. Turn the ignition switch on (IG).

    3. Turn the tester on.

    4. Clear the DTCs Click here.

    5. Start the engine and warm it up.

    6. Idle the engine for 5 minutes or more.

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

    8. Read the pending DTCs.

      Tech Tips


      • If a pending DTC is output, the system is malfunctioning.

      • If a pending DTC is not output, perform the following procedure.

    9. Drive the vehicle for 2 to 3 minutes.

      CAUTION:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    10. Idle the engine for 5 minutes or more.

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

    12. Read the pending DTCs.

      Result
      Result Proceed to
      DTC is not output A
      DTC P0016 or P0018 is output B

      Tech Tips

      DTC P0016 or P0018 may be stored when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. These foreign objects may then be captured by the oil filter.

      *1 Timing Mark

      Remove the cylinder head covers RH and LH.

    2. Turn the crankshaft to align the timing marks of the crankshaft.

    3. Align the notch of the crankshaft pulley to the "0" position.

    4. Check if the timing marks of the camshaft pulley and camshaft bearing cap align.

    5. Turn the crankshaft clockwise 360° if the timing marks do not align. Check if they align once again.

      OK
      The timing marks of the camshaft pulley and the camshaft bearing cap align when the notch of the crankshaft pulley is in the "0" position.
