SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P0365, P0390

DTC Code DTC Name
P0365 Camshaft Position Sensor "B" Circuit (Bank 1)
P0390 Camshaft Position Sensor "B" Circuit (Bank 2)

DESCRIPTION

The VVT sensors use a timing rotor (installed on each camshaft) and a Magnetic Resistance Element (MRE) type VVT sensor. The timing rotor (camshaft) has 3 protrusions. When it rotates, the magnetic vector (direction of magnetic field) applied to the VVT sensor magnetic resistance element varies, which causes its resistance to vary. This varying resistance is converted to voltage, and then modified into a rectangular waveform with Hi (approximately 4 V) and Lo (approximately 1 V) outputs. As a result, the actual camshaft position is detected and the position is output to the ECM.

MONITOR DESCRIPTION

If no pulse signal is transmitted by the VVT sensor (for exhaust camshaft) despite the camshaft rotating, or the rotation of the camshaft and the crankshaft is not synchronized, the ECM interprets this as a malfunction of the sensor.

  11. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

CAUTION / NOTICE / HINT

Tech Tips


  • If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.

  • Bank 1 refers to the bank that includes the No. 1 cylinder*.

    *: The No. 1 cylinder is the cylinder which is farthest from the transmission.

  • Bank 2 refers to the bank that does not include the No. 1 cylinder.

  • 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.

    3. Check that the timing marks of the camshaft timing intake gear assemblies and camshaft timing exhaust gear assemblies are at the positions shown in the illustration.

      OK
      The timing marks on the camshaft timing gears are aligned as shown in the illustration.

      Tech Tips


      • If the result is not as specified, check for mechanical malfunctions that may have affected the valve timing, such as a jumped tooth or stretching of the timing chain.

      • When checking the valve timing, make sure the camshaft timing intake gear assemblies are set to the most retarded position and the camshaft timing exhaust gear assemblies are set to the most advanced position. When the VVT system is normal and the engine is stopped, the camshaft timing intake gear assemblies stop at the center of their operation range and the camshaft timing exhaust gear assemblies stop at the most advanced position.
