			(Disconnected) MAF sensor/IAT sensor connector (4P) female terminals	(Disconnected) PCM connector E (80P) female terminals
		IG Mode	Courtesy of HONDA, U.S.A., INC.	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
	VCC1 open wire inspection	OFF			There is less than 1 Ohm
	SG1 open wire inspection	OFF			There is less than 1 Ohm
	FGP open wire inspection	OFF			There is less than 1 Ohm
	Refer to the Open/Shorted Wire Inspection Description for the method to inspect the shorted circuit below, then start to inspect according to circumstances.
	FGP shorted to ground inspection	OFF			There is more than 1 MOhm
	FGP shorted to power inspection	ON			Not shorted

Results 

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

VCC1 Shorted Wire Inspection 

Test Procedure 

• Preparation
  1. -

     MAF sensor/IAT sensor connector (4P): disconnected

  2. -

     CKP sensor connector (3P): disconnected

  3. -

     Rocker arm oil pressure sensor connector (3P) (USA/Canada models): disconnected

  4. -

     PCM connector E (80P): disconnected

• Procedure
  1. -

     Perform the inspection according to the following chart.

     Refer to the Open/Shorted Wire Inspection Description for the method to inspect the shorted circuit below, then start to inspect according to circumstances.

			(Disconnected) MAF sensor/IAT sensor connector (4P) female terminals
		IG Mode	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
	VCC1 shorted to ground inspection	OFF		There is more than 1 MOhm

Results 

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

MAF Sensor Inspection 

Test Procedure 

• Install a known-good MAF sensor/IAT sensor 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, the MAF sensor/IAT sensor 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.
