MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L>

13B-259

STEP 7. Check the right bank injector resistance at 
intermediate connector B-48.
(1) Disconnect the injector intermediate connector B-48.

(2) Measure the resistance between each injector side 

connector terminal.

a. Measure the resistance between terminal No. 1 and No. 

2 when measuring No. 1 cylinder.

b. Measure the resistance between terminal No. 1 and No. 

3 when measuring No. 3 cylinder.

c. Measure the resistance between terminal No. 1 and No. 

4 when measuring No. 5 cylinder.

• Resistance should be between 13 and 16 ohms [at 20°C 

(68

°F)].

Q: Is the resistance normal?

YES : Go to Step 10.
NO :  Go to Step 8.

STEP 8. Check connector B-01, B-05, B-26 at right bank 
injector for damage.
(1) Remove the intake manifold.
(2) Check the right bank injector connector, which deviates 

from the standard value at Step 7.

Q: Is the connector in good condition?

YES : Go to Step 9.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 14.

STEP 9. Check the right bank injector.
(1) Check the right bank injector connector, which deviates 

from the standard value at Step 7.

(2) Measure the resistance between injector side connector 

terminal No. 1 and No. 2.

Standard value: 13 

 16 ohms [at 20°C (68°F)]

Q: Is the resistance between 13 and 16 ohms?

YES : Repair harness wire between injector intermediate 

connector and right bank injector connector because 
of harness damage. Then go to Step 14.

NO :  Replace the injector. Then go to Step 14.

STEP 10. Check connector C-51, C-62 at ECM <M/T> or 
connector C-52, C-59 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 11.
NO :  Repair or replace it. Refer to GROUP 00E, Harness
