DTC Code DTC Name
P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
P0018 Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor A)

DESCRIPTION

Refer to DTC P0010 Click here.

DTC No. DTC Detection Condition Trouble Area
P0016

Valve timing on bank 1 intake side is deviated for 1 minute or more

(2 trip detection logic)

  • Valve timing

  • Camshaft timing gear assembly (bank 1)
P0018

Valve timing on bank 2 intake side is deviated for 1 minute or more

(2 trip detection logic)

  • Valve timing

  • Camshaft timing gear assembly (bank 2)

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 conditions are met: 1) the engine is idled, and then the engine 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

Tech Tips


  • Intelligent tester only:

    By using the Active Test's Control the VVT-iE Linear (Bank 1) or Control the VVT-iE Linear (Bank 2) function, it can be determined if the VVT-iE system is malfunctioning.


    1. Connect the intelligent tester to the DLC3.

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

    3. Start the engine and warm it up.

    4. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT-iE Linear (Bank 1) or Control the VVT-iE Linear (Bank 2) / VVT-iE Aim Angle (Bank 1) and VVT Change Angle (Bank 1) or VVT-iE Aim Angle (Bank 2) and VVT Change Angle (Bank 2).

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

      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 5 DegFR

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

  • 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.

PROCEDURE


  1. CHECK ANY OTHER DTC OUTPUT (P0016 OR P0018)


    1. Connect the intelligent tester to the DLC3.

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

    3. Clear the DTC Click here.

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

    5. Read the DTC.

      Result
      Result Proceed to
      DTC P0016 or P0018 is output A
      DTC P0016 or P0018 and other DTCs are output B

      Tech Tips

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

  2. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY (BANK 1 AND/OR BANK 2)


    1. Remove the camshaft timing control motor (bank 1 and/or bank 2) Click here.

    2. A0160R8

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

      OK
      Rotates smoothly

    3. Reinstall the camshaft timing control motor.


    NG

    REPLACE CAMSHAFT TIMING GEAR ASSEMBLY (BANK 1 AND/OR BANK 2) Click here

    OK

  3. INSPECT VALVE TIMING

    A015YIME02

    1. Remove the cylinder head cover bank 1 and bank 2.

    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 covers.


    NG

    ADJUST VALVE TIMING Click here

    OK

  4. CHECK WHETHER DTC OUTPUT RECURS


    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.

    3. Connect the intelligent tester to the DLC3.

    4. Switch the ECM from normal mode to check mode using the intelligent tester Click here.

    5. Start the engine and idle it for 5 minutes.

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

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

    8. Read the DTC.
