	CAMINB2, SG9 shorted wire to wire inspection	OFF			There is more than 1 MΩ
	Refer to the Open/Shorted Wire Inspection Description for the method to inspect the shorted circuit below, then start to inspect according to circumstances.
	CAMINB2 shorted to power inspection	ON			Not shorted
	CAMINB2 shorted to ground inspection	OFF			There is more than 1 MΩ

Results 

• If abnormal, there is a problem in the circuit.

CMP Sensor A (Bank 2) Inspection 

NOTE:  Since there is no direct method to test the inspection item, troubleshooting is performed using a known-good component.

Test Procedure 

• Install a known-good CMP sensor A (Bank 2) and attempt to reproduce the failure.

Results 

• If the failure is reproduced, there is a problem with other related components.
• If the symptom/DTC goes away, CMP sensor A (Bank 2) must be faulty.

PCM Inspection 

Test Procedure 

• If the other inspection item(s) indicated a normal condition, then it is determined that the remaining PCM is the cause.

Results 

• There is a problem with the PCM.
