TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L>

13B-171

STEP 6. Check for harness damage between throttle 
position sensor connector B-07 (terminal No. 4) and ECM 
connector C-58 (terminal No. 42) <M/T> or PCM connector 
C-55 (terminal No. 46) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 14.
NO :  Repair it. Then go to Step 14.

STEP 7. Check the continuity at throttle position sensor 
harness side connector B-07.
(1) Disconnect the connector B-07 and measure at the harness 

side.

(2) Measure the continuity between terminal No. 1 and ground.

• Should be less than 2 ohms.

Q: Is the continuity normal?

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