IGPS(LAF) Circuit Inspection

Test Procedure


		(Disconnected) A/F sensor (Sensor 1) connector (6P) female terminals
	IG Mode	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
IGPS(LAF) circuit inspection	ON		12 V battery voltage [circuit type 3]

Results

If abnormal, there is a problem in the circuit.
If the power supply inspection of the above table showed abnormally, do the additional Power Supply Inspection , to locate the failure.

	IG Mode	Courtesy of HONDA, U.S.A., INC.	Courtesy of HONDA, U.S.A., INC.	Normal Conditions
AFHT 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.
AFHT shorted to ground inspection	OFF			There is more than 1 MOhm

Results

PCM Inspection

Test Procedure

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