DTC Code DTC Name
P001600 Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A
P001800 Crankshaft Position - Camshaft Position Correlation Bank 2 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 intake camshaft, cam timing oil control solenoid assembly, camshaft timing gear bolt (camshaft timing oil control valve assembly [for intake camshaft]) and operating the camshaft timing gear; and 2) changing the relative positions of the camshaft and crankshaft.

MONITOR DESCRIPTION

To monitor the correlation of the intake camshaft position and crankshaft position, the ECM checks the VVT learned value while the engine is idling. The VVT learned value is calibrated based on the camshaft position and crankshaft position. The intake valve timing is set to the neutral position while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM illuminates the MIL and stores a DTC.

  17. Enter the following menus: Powertrain / Engine / Trouble Codes [G].

  18. 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.

    Tech Tips


    • If the judgment result is NORMAL, the system is normal.

    • If the judgment result is ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

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 transaxle.

  • Bank 2 refers to the bank that does not include the No. 1 cylinder.

  • The monitor for this DTC detects when the timing chain is shifted by one tooth or more.

  • Read freeze frame data using the GTS. 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. PERFORM SIMULATION TEST (CHECK FOR ABNORMAL NOISE)


    1. Start the engine.

    2. Check for abnormal noise (rattling sounds) from the camshaft timing gear assembly with the engine idling.

      Result
      Result Proceed to
      Abnormal noise (rattling sound) from the camshaft timing gear assembly is heard. A
      Abnormal noise (rattling sound) from the camshaft timing gear assembly is not heard. B

      Tech Tips


      • As the engine speed increases, the camshaft timing gear assembly lock pins will release and the abnormal noise (rattling sound) will disappear.

      • Perform "Inspection After Repair" after replacing the camshaft timing gear assembly.
