My first one failed back in nov of last year it was the right bank one. The left bank o2 failed last week. Now I put my cam in my car and the right one has taken a dump on me again. Thats 3 o2's in 3 months or so. I don't know what is causing them to go out. The first to set a bank faliures. This new one set a code 64. Which is righ tbank o2 sensor circuit. Check wiring and connections from the o2 sensor to the ecm/pcm. Lean exhaust indicated. Anyone know why my car is frying o2's?
