I have a 1999 Camry, which I love. My check engine light was on and the car wouldn't pass the emission test, I had it checked out and the 1st Oxygen sensor was bad. I replaced it, reset the computer, and it was great! The light went off, and my car passed. This lasted for about 6 hours, then the check engine light came back on. I took it back to the same place, had it tested again. The same code came up, so I thought I got a bad part. I replaced the part again, the light went off, and I thought I was good again. This time it only took about 30 minutes for it to come back on again. I have searched for the answer to this, but does anyone know what would be causing the O2 sensor to go out over and over again? There is no other codes coming up during diagnosis.
