MONITOR DESCRIPTION
2 seconds or more after the power switch has been turned on (IG), if the output voltage of the camshaft position sensor is higher than 4.7 V for 4 seconds or more, the ECM determines that the camshaft position sensor circuit is malfunctioning and illuminates the MIL and stores a DTC.

CAUTION / NOTICE / HINT
- NOTICE:
- ·
Vehicle Control History may be stored in the hybrid vehicle control ECU if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the Freeze Frame Data and Vehicle Control History can be useful for troubleshooting.
(Select Powertrain in Health Check and then check the time stamp data.)
·If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.
- 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.

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 connector.
Turn the power switch on (IG).
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Condition Specified Condition C10-3 (VC) - Body ground Power switch on (IG) 4.5 to 5.5 V
- Result:
Result Proceed to Higher than 5.5 V A 4.5 to 5.5 V B Below 4.5 V C

Disconnect the camshaft position sensor connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition C10-3 (VC) or C155-114 (VCV1) - Other terminals Always 10 kΩ or higher
- Result:
Proceed to OK NG
