DESCRIPTION

The exhaust camshaft VVT sensor (EV1 and EV2 signals) consists of a magnet and MRE (Magnetoresistive Element).

The exhaust camshaft has 3 teeth on its outer circumference. When the exhaust camshaft rotates, changes occur in the air gaps between the 3 teeth and MRE, which affects the magnetic field. As a result, the resistance of the MRE fluctuates. The VVT sensor converts the exhaust camshaft rotation data into pulse signals, uses the pulse signals to determine the camshaft angle, and sends the data to the ECM.

DTC No. DTC Detection Condition Trouble Area

P0365

P0390

 No VVT sensor signal is sent to the ECM at an engine speed of 600 rpm or more (1 trip detection logic).

  • Open or short in VVT sensor for exhaust camshaft circuit

  • VVT sensor for exhaust camshaft

  • Exhaust camshaft

  • Timing chain jumped tooth

  • ECM

P0367

P0392

 Output voltage of VVT sensor is below 0.3 V for 4 seconds (1 trip detection logic).

  • Open or short in VVT sensor for exhaust camshaft circuit

  • VVT sensor for exhaust camshaft

  • Exhaust camshaft

  • Timing chain jumped tooth

  • ECM

P0368

P0393

 Output voltage of VVT sensor is higher than 4.7 V for 4 seconds (1 trip detection logic).

  • Open or short in VVT sensor for exhaust camshaft circuit

  • VVT sensor for exhaust camshaft

  • Exhaust camshaft

  • Timing chain jumped tooth

  • ECM

MONITOR DESCRIPTION

If no signal is transmitted by the VVT 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 at below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Start the engine and run it at idle for 10 seconds or more.

INSPECTION PROCEDURE

Tech Tips


  • Read freeze frame data using the GTS. 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.

  • 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.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (SENSOR POWER SOURCE)

      (to VVT Sensor)

      Disconnect the VVT sensor connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      3 (VC2) - Body ground Engine switch on (IG) 4.5 to 5.0 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK HARNESS AND CONNECTOR (VVT SENSOR - ECM)


    1. Disconnect the VVT sensor connector.

    2. Disconnect the ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      C22-1 (EX+) - C54-69 (EV1+) Always Below 1 Ω
      C22-2 (EX-) - C54-68 (EV1-) Always Below 1 Ω
      C23-1 (EX+) - C54-64 (EV2+) Always Below 1 Ω
      C23-2 (EX-) - C54-65 (EV2-) Always Below 1 Ω
      C22-1 (EX+) or C54-69 (EV1+) - Body ground Always 10 kΩ or higher
      C22-2 (EX-) or C54-68 (EV1-) - Body ground Always 10 kΩ or higher
      C23-1 (EX+) or C54-64 (EV2+) - Body ground Always 10 kΩ or higher
      C23-2 (EX-) or C54-65 (EV2-) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. CHECK SENSOR INSTALLATION (VVT SENSOR FOR EXHAUST CAMSHAFT)


    1. A01EOGXE18

      Check the VVT sensor installation.

      OK
      Sensor is installed correctly.

    NG

    OK

  4. INSPECT EXHAUST CAMSHAFT


    1. Check the teeth of the camshaft.

      OK
      Teeth do not have any cracks or deformation.

    NG

    REPLACE EXHAUST CAMSHAFT Click here

    OK

  5. REPLACE VVT SENSOR

  6. CHECK WHETHER DTC OUTPUT RECURS


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Clear DTCs Click here.

    5. Start the engine and idle it for 10 seconds or more.

    6. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.

    7. Read DTCs.
