OK,
The check engine light is on again. I just replaced the two front O2 sensors but am getting the code about "02 Sensor 1 bank one no activity" again. Also I had the code P0455 which is gross emissions leak. A new gas cap fixed that for about 170 miles, now it is back on. Strange thing is, I checked the gas cap and retightened it to see if I might not have got is closed. So, I erased the codes to see if the light would come back on, BUT the light never went out. Its like I cannot reset the codes now. Tried it twice but no luck. What the ? This thing is about to drive me crazy. The inspection sticker expired in November and I haven't got it ready for a new inspection yet. Has anyone seen anything like this before????

For what its worth. I was getting O2 codes with "no activity" when I replaced them, then replaced them again... and STILL had the code after hard resets, I had no other option but to take it to the dealer.

My ECU was "stuck" thinking it was bad. You can try a re-flash first, but that didn't work on mine, they had to replace it. Supposedly it should have like an 4-6 year (?) 90,000 mile warranty.... well i had 92,000 miles. The dealer cut me a deal saying that they would replace it at no charge for the new ECU but I would have to pay for the labor. Needless to say after checking forums apparently its easy to get to the ECU; now rather thats true or not Im not sure.

Thats just my experience.

Thanks Scott. That makes some sense. My odometer is flashing also which has got to be reset. Maybe someone else will chime in with some other experiences and solution.
