DTC P0019 Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)


DESCRIPTION

In the VVT 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 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

P0016
Deviation in crankshaft position sensor signal and VVT sensor 1 (for intake camshaft (bank 1)) signal (2 trip detection logic)
  1. Mechanical system (Timing chain has jumped tooth or chain stretched)
  2. ECM
P0017
Deviation in crankshaft position sensor signal and VVT sensor 1 (for exhaust camshaft (bank 1)) signal (2 trip detection logic)
  1. Mechanical system (Timing chain has jumped tooth or chain stretched)
  2. ECM
P0018
Deviation in crankshaft position sensor signal and VVT sensor 2 (for intake camshaft (bank 2)) signal (2 trip detection logic)
  1. Mechanical system (Timing chain has jumped tooth or chain stretched)
  2. ECM
P0019
Deviation in crankshaft position sensor signal and VVT sensor 2 (for exhaust camshaft (bank 2)) signal (2 trip detection logic)
  1. Mechanical system (Timing chain has jumped tooth or chain stretched)
  2. ECM

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. 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 (Click here).

  1. Remove the cylinder head covers RH and LH.

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

  1. Check that the timing marks of the camshaft timing gears are aligned with the timing marks of the bearing cap 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 covers.
