SFI SYSTEM, Diagnostic DTC:P0017, P0019

DTC Code DTC Name
P0017 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)
P0019 Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)

DESCRIPTION

In the VVT (Variable Valve Timing) system, the appropriate exhaust valve open and close timing is controlled by the ECM. The ECM performs exhaust valve control by performing the following: 1) controlling the exhaust camshaft and camshaft timing oil control valve assembly (for exhaust camshaft), and operating the camshaft timing exhaust gear assembly; and 2) changing the relative positions of the camshaft and crankshaft.

DTC No. DTC Detection Condition Trouble Area
P0017 Deviations in crankshaft and VVT sensor (for exhaust camshaft) signals (2 trip detection logic)
  • Valve timing

  • Camshaft timing oil control valve assembly for exhaust camshaft (bank 1, 2)

  • Oil control valve filter (bank 1, 2)

  • Camshaft timing exhaust gear assembly

  • ECM

P0019 Deviations in crankshaft and VVT sensor (for exhaust camshaft) signal (2 trip detection logic)

MONITOR DESCRIPTION

To monitor the correlation of the exhaust camshaft position and crankshaft position, the ECM checks the VVT learning value while the engine is idling. The VVT learning 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 learning value is out of the specified range in consecutive driving cycles, the ECM illuminates the MIL and sets the DTC P0017 (Bank 1) or P0019 (Bank 2).

INSPECTION PROCEDURE

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 transmission.

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

  • 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. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0017 OR P0019)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    5. Read the DTCs.

      Tech Tips

      If any DTCs other than P0017 or P0019 are output, troubleshoot those DTCs first.
