▶

Go to "2.Check open in signal circuit" as follows.

2.

Check open in signal circuit

1)

IG KEY "OFF", ENGINE "OFF".

2)

Disconnect MAFS connector and ECM connector.

3)

Check continuity between MAFS connector terminal 3 and ECM connector (C230-K) terminal 89.

Specification : Continuity (below 1.0

Ω

)

4)

Is the measured resistance within the specification?

YES

▶

Go to "3.Check short to battery in signal circuit " as follows

GROUND CIRCUIT INSPECTION

EC57554A

1.

IG KEY "OFF", ENGINE "OFF".

2.

Disconnect MAFS connector and ECM connector

3.

IG KEY "ON"

4.

Measure the voltage of terminal 3 of MAFS connector. [ TEST "A" ]

5.

Measure the voltage of MAFS terminal 3 and terminal 2. [ TEST "B" ]
( terminal 3 : Check + prove , terminal 2 : Check - prove )

Specification : the voltage difference between TEST "A" and TEST "B" is within 200mV

6.

Is the measured voltage within the specification?

YES

▶

Go to "Component Inspection"

NO

▶

When "B" voltage is not detected : Repair open in ground circuit and go to "Verification of Vehicle Repair".

▶

When the voltage difference between "A" and "B" is above 200mV : Eliminate the causes of excessive resistance

and go to "Verification of Vehicle Repair".
