DTC Code DTC Name
P0365 Camshaft Position Sensor "B" Circuit (Bank 1)

P0368 Camshaft Position Sensor "B" Circuit High Input (Bank 1)

DESCRIPTION

The exhaust camshaft's Variable Valve Timing (VVT) sensor (G signal) consists of a magnet and MRE element.

The exhaust camshaft has a sensor plate with 3 teeth on its outer circumference.

When the exhaust camshaft rotates, changes occur in the air gaps between the 3 teeth and MRE element, which affects the magnet. As a result, the resistance of the MRE material fluctuates. The camshaft position sensor converts the exhaust camshaft rotation data to pulse signals, and uses the pulse signals to determine the camshaft angle, which it sends to the ECM. Then the ECM uses this data to control fuel injection timing and ignition timing. The crankshaft angle sensor plate has 34 teeth. The pickup coil generates 34 signals for each crankshaft revolution. Based the G signal and actual crankshaft angle, the ECM detects the normal crankshaft angle. Also, based on the NE signal, the ECM detects the engine speed.

CAUTION / NOTICE / HINT

Tech Tips


  • Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition 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.

  • If no problem is found through this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0365, P0367 OR P0368)

      Result
      Result Proceed to
      DTC P0365, P0367 or P0368 is output A
      DTC P0365, P0367 or P0368 and other DTCs are output B

      Tech Tips

      If any DTCs other than P0365, P0367 or P0368 are output, troubleshoot those DTCs first.
