MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L>

13B-127

STEP 8. Check the continuity at intake air temperature 
sensor harness side connector B-14.
(1) Disconnect the connector B-14 and measure at the harness 

side.

(2) Check for the continuity between terminal 5 and ground.

• Should be less than 2 ohms.

Q: Is the continuity normal?

YES : Replace the ECM or PCM. Then go to Step 11.
NO :  Go to Step 9.
