TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L>

13B-655

STEP 8. Check for open circuit and short circuit to ground 
between evaporative emission purge solenoid connector 
B-33 (terminal No.1) and ECM connector C-51 (terminal No. 
16) <M/T> or PCM connector C-52 (terminal No. 34) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 12.
NO :  Repair it. Then go to Step 12.
