DTC Code DTC Name

DESCRIPTION

The camshaft position sensor for the exhaust camshaft (EV signal sensor) consists of a magnet and an MRE element.

The exhaust camshaft has a timing rotor for the camshaft position sensor. When the camshaft rotates, changes occur in the air gaps between the timing rotor and MRE element, which affects the magnetic field. As a result, the resistance of the MRE material fluctuates. The camshaft position sensor converts the 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 duration, injection timing and the Variable Valve Timing (VVT) system.

Tech Tips

DTC P0365, P0367 and P0368 indicate a malfunction relating to the exhaust camshaft position sensor circuit (the wire harness between the ECM and exhaust camshaft position sensor, and the exhaust camshaft position sensor itself).

INSPECTION PROCEDURE

Tech Tips


  • 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

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