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


DESCRIPTION

The ECM optimizes the valve timing by using the VVT (Variable Valve Timing) system to control the intake camshaft. The VVT system includes the ECM, the camshaft timing oil control valve assembly and the VVT controller (camshaft timing gear assembly). The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller can advance or retard the intake camshaft.

DTC No.
DTC Detection Condition
Trouble Area
P0016
Deviations in crankshaft and camshaft position sensor signals (2 trip detection logic)
  1. Mechanical system (Timing chain has jumped a tooth or chain stretched)
  2. Camshaft timing oil control valve assembly
  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 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 the specified range in consecutive driving cycles, the ECM illuminates the MIL and stores the DTC.

    HINT:
    1. If the judgment result shows NORMAL, the system is normal.
    2. If the judgment result shows ABNORMAL, the system has a malfunction.
    3. If the judgment result shows INCOMPLETE or N/A, perform steps [E] through [G].
  13. Drive the vehicle for 2 to 3 minutes [E].
    CAUTION:
    When performing the confirmation driving pattern, obey all speed limits and traffic laws.
  14. Idle the engine for 5 minutes or more [F].

  16. Read the pending DTCs.
    HINT:
    1. If a pending DTC is output, the system is malfunctioning.
    2. If a pending DTC is not output, perform the following procedure.
  17. Check the DTC judgment result.
  18. If the judgment result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs (COROLLA_ZRE142 RM000000PDK0ZBX.html).
    HINT:

INSPECTION PROCEDURE

HINT:
  1. The monitor for this DTC detects when the timing chain is shifted by one tooth or more.
  2. 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.
