SFI SYSTEM(w/ GPF), Diagnostic DTC:P036511, P036515

DTC Code DTC Name
P036511 Camshaft Position Sensor "B" Bank 1 Circuit Short to Ground
P036515 Camshaft Position Sensor "B" Bank 1 Circuit Short to Battery or Open

DESCRIPTION

The camshaft position sensor for the exhaust camshaft (EV1 signal) consists of a magnet and MRE (Magneto-Resistive 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, 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, uses the pulse signals to determine the camshaft angle, and sends it to the ECM. Then the ECM uses this data to control fuel injection duration, injection timing and the Variable Valve Timing (VVT) system.

MONITOR DESCRIPTION

When the camshaft position sensor (for exhaust camshaft) output voltage is less than 0.3 V, or higher than 4.7 V, continuously for 4 seconds or more, the ECM illuminates the MIL and stores a DTC.

MONITOR STRATEGY

Required Sensors/Components (Main) Exhaust camshaft position sensor
Required Sensors/Components (Related) Crankshaft position sensor
Frequency of Operation Continuous

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the engine switch off and wait for at least 30 seconds.

  5. Turn the engine switch on (IG) and turn the GTS on.

  6. Start the engine.

  7. Idle the engine for 10 seconds or more [A].

  8. Enter the following menus: Powertrain / Engine / Trouble Codes [B].

  9. Read the pending DTCs.

    Tech Tips


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

    • If a pending DTC is not output, perform the following procedure.

  10. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  11. Input the DTC: P036511 or P036515.

  12. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions

    Tech Tips


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

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE, perform steps [A] and [B] again.

CAUTION / NOTICE / HINT

Tech Tips


  • 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.

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

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (POWER SOURCE OF CAMSHAFT POSITION SENSOR)

    Tech Tips

    Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

      (to Camshaft Position Sensor for Exhaust Camshaft)

      Disconnect the camshaft position sensor for exhaust camshaft connector.

    2. Turn the engine switch on (IG).

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      C26-3 (VC2) - Body ground Engine switch on (IG) 4.5 to 5.5 V
      C26-1 (VVE+) - Body ground Engine switch on (IG) 3.0 to 5.5 V

    4. Turn the engine switch off and wait for at least 30 seconds.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      C26-3(VC2) - C26-1(VVE+) Engine switch off 1.425 to 1.575 kΩ
      C26-2(VVE-) - Body ground Always Below 1 Ω

  2. CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR - ECM)


    1. Disconnect the camshaft position sensor for exhaust camshaft connector.

    2. Disconnect the ECM connector.

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

      Standard Resistance
