Camshaft Position Sensor "B" Bank 1 Signal Stuck in Range

No camshaft position sensor (for exhaust camshaft) signal to ECM while engine cranking (1 trip detection logic).
  • Open or short in camshaft position sensor (for exhaust camshaft) circuit
  • Camshaft position sensor (for exhaust camshaft)
  • Exhaust camshaft
  • ECM

Comes on

SAE: P0365

P036531

Camshaft Position Sensor "B" Bank 1 No Signal

No camshaft position sensor (for exhaust camshaft) signal for 5 seconds at an engine speed of 600 rpm or higher (1 trip detection logic).

*
  • Open or short in camshaft position sensor (for exhaust camshaft) circuit
  • Camshaft position sensor (for exhaust camshaft)
  • Exhaust camshaft
  • ECM

Comes on

SAE: P0365

*: When the engine is being stopped or started automatically by stop and start system control, the ECM does not monitor the camshaft position sensor signal.

  • Reference: Inspection using an oscilloscope.

MONITOR DESCRIPTION

If no pulse signal is transmitted by the camshaft position 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.

CONFIRMATION DRIVING PATTERN

  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the GTS on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the ignition switch off and wait for at least 30 seconds.
  6. Start the engine [A].
  7. Idle the engine for 10 seconds or more [B].
  8. Turn the GTS on.
  9. Enter the following menus: Powertrain / Engine / Trouble Codes [C].
  10. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  11. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  12. Input the DTC: P03652A or P036531.
  13. 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

    HINT:

    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system is malfunctioning.
    • If the judgment result is INCOMPLETE, perform steps [B] through [C] again.

CAUTION / NOTICE / HINT

HINT:

  • 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

HINT:

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

(a) Disconnect the camshaft position sensor (for exhaust camshaft) connector.

(b) Turn the ignition switch to ON.

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

Standard Voltage:

Tester Connection

CHECK SENSOR INSTALLATION AND CONDUCT VISUAL INSPECTION (CAMSHAFT POSITION SENSOR (FOR EXHAUST CAMSHAFT))

*a

Clearance

(a) Visually check the camshaft position sensor (for exhaust camshaft) for damage.

(b) Check the camshaft position sensor (for exhaust camshaft) installation condition.

OK:

The camshaft position sensor (for exhaust camshaft) does not have any damage and is installed properly.

NG

SECURELY REINSTALL CAMSHAFT POSITION SENSOR (FOR EXHAUST CAMSHAFT)

3.

INSPECT EXHAUST CAMSHAFT (TIMING ROTOR)

(a) Check the timing rotor of the exhaust camshaft.

OK:

Camshaft timing rotor does not have any cracks or deformation.

HINT:

Perform "Inspection After Repair" after replacing the exhaust camshaft.
