IG KEY "OFF", ENGINE "OFF".
Disconnect CMPS connector and APS connector.
Check that sensor connector power supply is within the specification after turning IG KEY "ON".
Connect CMPS connector and APS connector in turn.
Measure the voltage of power circuit of each sensor with all connector connected.
Specification :
☞ APS : Sensor power supply should not change as connecting APS connector. ( If the change of sensor power supply occur as connecting sensor connector, this means the occurrence of short inside of sensor.)
☞ CMPS : Sensor signal voltage will be droped approximately 0.2V not only when connecting cam shaft position sensor but also when locating the cam shaft in case.
Does change of sensor power supply occur as connecting sensor connector?
YES
Replace related sensors.(CMPS/APS)
NO
Go to "Verification of Vehicle Repair".
