DTC P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)

DTC 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.
Detection Condition
Trouble Area
P0016
Deviation in crankshaft position sensor signal and camshaft position sensor (for intake camshaft) signal
(2 trip detection logic)
  1. Mechanical system (Timing chain has jumped tooth or chain stretched)
  2. Camshaft timing oil control valve assembly (for intake camshaft)
  3. Camshaft timing gear assembly (for intake camshaft)
  4. ECM
P0017
Deviation in crankshaft position sensor signal and camshaft position sensor (for exhaust camshaft) signal
(2 trip detection logic)
  1. Mechanical system (Timing chain has jumped tooth or chain stretched)
  2. Camshaft timing oil control valve assembly (for exhaust camshaft)
  3. Camshaft timing gear assembly (for exhaust camshaft)
  4. ECM

MONITOR DESCRIPTION

To monitor the correlation of the intake 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 intake valve timing is set to the most retarded angle while the engine is idling. If the VVT learning value is out of specified range in consecutive driving cycles, the ECM illuminates the MIL and sets the DTC P0016.
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 specified range in consecutive driving cycles, the ECM illuminates the MIL and sets the DTC P0017.
