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 gaps between the camshaft and crankshaft.

DTC No.
DTC Detection Condition
Trouble Area
P0016
Deviation between crankshaft and camshaft position sensor signals (2 trip detection logic)
  1. Mechanical system (Timing chain has jumped tooth or chain stretched)
  2. ECM

WIRING DIAGRAM

Refer to DTC P0335 (Link).

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. 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.
1.CHECK VALVE TIMING (CHECK FOR LOOSE AND JUMPED TOOTH OF TIMING CHAIN)

  1. Remove the cylinder head cover.

  1. Turn the crankshaft pulley, and align its groove with the timing mark "0" on the timing chain cover.

  1. Check that the timing marks on the camshaft timing sprocket and camshaft timing gear are facing upward as shown in the illustration.

    1. If not, turn the crankshaft 1 revolution (360°), then align the marks as above.
    OK:
    Timing marks on camshaft timing gears are aligned as shown in the illustration.

  1. Reinstall the cylinder head cover.

4.CHECK WHETHER DTC OUTPUT RECURS
NOTICE:
After replacing the ECM or adjusting intake valve timing, confirm that the DTC output does not recur.

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to the ON position and turn the tester on.

  1. Clear the DTCs (CAMRY_ACV40 RM000000PDK081X.html).

  1. Switch the ECM from normal mode to check mode using the tester (CAMRY_ACV40 RM000000PDL01VX.html).

  1. Start the engine and warm it up.

  1. Allow the engine to idle for 1 minute or more, and then drive the vehicle for 1 minute or more.

  1. Confirm that no DTC is set using the tester.

    OK:
    No DTC output
