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

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 affect 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).

Reference: Inspection using an oscilloscope Click here.

MONITOR DESCRIPTION

If no signal is transmitted by the camshaft position sensor despite the engine running, or the rotations of the camshaft and crankshaft are not synchronized, the ECM interprets this as a malfunction of the sensor.

Also, when the sensor output voltage remains below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Turn the ignition switch to ON and wait for 10 seconds or more.

CAUTION / NOTICE / HINT

Tech Tips


  • 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.

  • 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)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the tester on.

    4. Enter the following menus: Powertrain / Engine and ECT / DTC.

    5. Read the DTCs.

      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.
