Hi: Can someone help me? My minivan with 3.3L burned up an O2 sensor
4 weeks ago. Took out the alternator and battery. Shop had a hard time getting the wiring straight as it melted. Actually replaced the O2 sensor a second time. Car still has no power and hesitates when you give it the gas. Suggestions? I need to get my van back.Your O2 sensor destroyed your alternator and battery?????
When my O2 sensor went, all that happened was hesitation under load (going up hill) and the odd spit-back.
Replacement was about $100 and took less than 20 min.
If your alternator and battery went, causing a melt-down of wiring, I would suggest that the O2 sensor was NOT at fault.
No idea where to start, but it sounds nasty.
