MONITOR DESCRIPTION

When the engine is running and no camshaft position sensor (for exhaust camshaft) signal is received for 5 seconds or more, the ECM determines that the camshaft position sensor (for exhaust camshaft) circuit is malfunctioning and illuminates the MIL and stores a DTC.

CAUTION / NOTICE / HINT

HINT:

  • If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
  • 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 DTC OUTPUT (DTC P036531 AND P036511 OR P036531)

(a) Read the DTCs.
