MONITOR DESCRIPTION

When the engine is cranking and no camshaft position sensor (for exhaust camshaft) signal is received for 2 times, the ECM determines that the camshaft position sensor (for exhaust camshaft) circuit is malfunctioning and illuminates the MIL and stores a DTC.

MONITOR STRATEGY

TYPICAL ENABLING CONDITIONS

TYPICAL MALFUNCTION THRESHOLDS

CONFIRMATION DRIVING PATTERN

HINT:

• After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

  Click here

• When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

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. Proceed to the next screen and enter the DTC to be checked.
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.
    • [A] to [C]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

    • When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT

HINT:

• If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
• DTC P03652A may be stored due to poor engine cranking. Before performing troubleshooting for this DTC, perform the check engine cranking operation procedure.

• 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.

PROCEDURE

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:

(d) Turn the ignition switch off.

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

Standard Resistance:

NG

GO TO STEP 4

OK

(a) Remove the camshaft position sensor (for exhaust camshaft).

(b) Confirm that there is no oil on the connecting parts of the camshaft position sensor (for exhaust camshaft) connector.

OK:

There is no oil on the connecting parts of the camshaft position sensor (for exhaust camshaft).

NG

REPLACE CAMSHAFT POSITION SENSOR (FOR EXHAUST CAMSHAFT)

OK

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

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

Standard Resistance:

OK

REPLACE ECM

NG

REPLACE CAMSHAFT POSITION SENSOR (FOR EXHAUST CAMSHAFT)

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

(b) Disconnect the ECM connector.

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

Standard Resistance:

OK

REPLACE ECM

NG

REPAIR OR REPLACE HARNESS OR CONNECTOR
