SFI SYSTEM, Diagnostic DTC:P0016, P0017

DTC Code DTC Name
P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
P0017 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)

DESCRIPTION

In the VVT (Variable Valve Timing) system, the appropriate intake and exhaust valve open and close timing is controlled by the ECM. The ECM performs intake and exhaust valve control by performing the following: 1) controlling the camshaft and camshaft timing oil control valve assembly, 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 crankshaft position sensor signal and camshaft position sensor (for intake camshaft) signal

(2 trip detection logic).

  • Valve timing

  • Camshaft timing oil control valve assembly (for intake camshaft)

  • Oil control valve filter

  • Camshaft timing gear assembly (for intake camshaft)

  • ECM
P0017

Deviation in crankshaft position sensor signal and camshaft position sensor (for exhaust camshaft) signal

(2 trip detection logic).

  • Valve timing

  • Camshaft timing oil control valve assembly (for exhaust camshaft)

  • Oil control valve filter

  • Camshaft timing exhaust gear assembly

  • 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.

To monitor the correlation of the exhaust 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 exhaust valve timing is set to the most advanced 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 P0017.

  8. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].

  9. 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.

  10. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  11. Input the DTC: P0016 or P0017.

  12. Check the DTC judgment result.

    Techstream Display Description

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips

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

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

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

    • If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

Tech Tips

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

  • Read freeze frame data using the Techstream. 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. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0016 AND P0017)

    1. Connect the Techstream to the DLC3.
