MONITOR DESCRIPTION

These DTCs are output when a valve timing deviation condition is detected. While the vehicle is being driven or the engine is idling (after the battery terminals are reconnected), if a valve timing deviation is detected during the valve timing initialization operation, it is determined that a malfunction has occurred. If this condition is detected while driving, a DTC is output (2 trip detection logic). However, if the valve timing is deviated, the camshaft position sensor malfunction DTC P1340 may be output.

A DTC is output if the following occurs: 1) the engine is idled, and then the power switch is turned off; and 2) the engine is started and the engine is idled.

DTC P0016 and/or P0018 may be output if the battery is reconnected and the engine is started while the following are disconnected from the camshaft timing control motor: 1) power source harness or connector; or 2) ECM harness or connector.

If P0016 and/or P0018 is output, check if the harness or connector is disconnected.

INSPECTION PROCEDURE

Tip:

  • By using the Active Test's Control the VVT-iE Linear (Bank1) or Control the VVT-iE Linear (Bank2) function, it can be determined if the VVT-iE system is malfunctioning.


    1. Put the engine in inspection mode (see pageClick here).

    2. Connect the intelligent tester to the DLC3.

    3. Turn the tester ON.

    4. Clear the DTC (see pageClick here).

    5. Warm up the engine.

    6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT-iE Linear (Bank1) or Control the VVT-iE Linear (Bank2) / All Data / VVT-iE Aim Angle #1 and VVT Change Angle #1 or VVT-iE Aim Angle #2 and VVT Change Angle #2.

    7. Perform the Active Test operation with the engine speed at 1500 rpm.

      Table 1. OK
      Active Test Movement Order Difference between "VVT-iE Aim Angle" and "VVT Change Angle"
      0 deg → 10 deg → 20 deg → 40 deg → 10 deg → 0 deg → 10 deg → END Within 4 DegFR

  • 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.

  • When viewed from the rear of the engine assembly, Bank 1 is on the left side and Bank 2 is on the right side.

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


    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.

    INSPECT CAMSHAFT TIMING GEAR ASSEMBLY (for Bank 1 or Bank 2)


    1. Turn the power switch off.

    2. Remove the camshaft timing control motor (for Bank 1 or Bank 2) (see pageClick here).

    3. A01H0LO

      Check if the camshaft timing gear assembly's eccentric shaft rotates smoothly.

      OK
      Rotates smoothly

    INSPECT VALVE TIMING


    1. Remove the cylinder head cover sub-assembly (for Bank 1 and Bank 2) (see pageClick here).

    2. Turn the crankshaft pulley, and align its groove with the timing mark "0" of the timing chain cover.

    3. Check that the timing marks of the camshaft timing gears and camshaft timing exhaust gears are at the positions shown in the illustration.

      OK
      Timing marks on camshaft timing gears are aligned as shown in the illustration.

    4. Reinstall the cylinder head cover sub-assembly (for Bank 1 and Bank 2) (see pageClick here).

    CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. To initialize the ECM's valve timing, disconnect the cable from the negative (-) battery terminal for 1 minute.

    2. Connect the cable to the negative (-) battery terminal (see pageClick here).

    3. Connect the intelligent tester to the DLC3.

    4. Turn the power switch on (IG) and turn the intelligent tester on.

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

    6. Idle the engine for 5 minutes.

    7. Drive the vehicle in an urban area for approximately 10 minutes.

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

    9. Read the DTCs.
