DTC 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, and operating the camshaft timing gear; and 2) changing the relative positions of the camshaft and crankshaft.

DTC No.
DTC Detection Condition
Trouble Area
P0016
Deviation in the crankshaft position sensor signal and camshaft position sensor signal (2 trip detection logic).
  1. Valve timing
  2. Camshaft timing oil control valve assembly (bank 1)
  3. Oil control valve filter
  4. Camshaft timing gear assembly
  5. ECM

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 most retarded angle 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 DTC P0016.

INSPECTION PROCEDURE

HINT:
  1. The monitor for this DTC detects when the timing chain is shifted by 2 to 3 teeth or more.
  2. 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.
1.CHECK FOR ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the intelligent tester on.

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

  1. Read the DTCs.

    Result
    Result
    		Proceed to

    		A
    P0016 and other DTCs are output
    		B
    HINT:
    If any DTCs other than P0016 are output, perform troubleshooting for those DTCs first.
