STEP 4. Check for short circuit to ground between right 
bank heated oxygen sensor (front) connector B-27 
(terminal No. 4) and ECM connector C-62 (terminal No. 72) 
<M/T> or PCM connector C-59 (terminal No. 72) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 5.
NO :  Repair it. Then go to Step 5.
