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.
MONITOR STRATEGY
| Required Sensors/Components (Main) | Camshaft position sensor (for exhaust camshaft) |
| Required Sensors/Components (Related) | Crankshaft position sensor |
| Frequency of Operation | Continuous |
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.
·When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Start the engine.
Idle the engine for 10 seconds or more [A].
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes [B].
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.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P03652A or P036531.
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 [A] through [B] again.
·[A] to [B]: 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 battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
WIRING DIAGRAM
Refer to DTC P036511.
CAUTION / NOTICE / HINT
- HINT:
- ·
If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
·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

(to Camshaft Position Sensor (for Exhaust Camshaft)) |
- HINT:
-
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
Disconnect the camshaft position sensor (for exhaust camshaft) connector.
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Switch Condition Specified Condition C12-3 (VC2) - Body ground Ignition switch ON 4.5 to 5.5 V C12-1 (VVE+) - Body ground Ignition switch ON 3.0 to 5.0 V
Turn the ignition switch off and wait for at least 30 seconds.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Switch Condition Specified Condition C12-3 (VC2) - C12-1 (VVE+) Ignition switch off 1.425 to 1.575 kΩ C12-2 (VVE-) - Body ground Ignition switch off Below 1 Ω
- Result:
Proceed to OK NG

Visually check the camshaft position sensor (for exhaust camshaft) for damage.
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.
- Result:
Proceed to OK NG
