Autozone diagnostic said "code 133: 02 sensor slow response, bank 1 sensor 1" which the dude said was 1 of 3 things:

1. 02 sensor defective
2. fuel system rich or lean
3. wire loose

I've done some thread searching but no mention of this code. Is this sensor easy to get to? He said it's near the cat converter.

New one $73.99 so not a big deal but free is better.

Going to reset ECU this weekend to see if that does anything.

Thanks -

 

i got a similar code....dont remember the number....but the computer said it was my 02 sensor. It was really my cat though. So paid $230 for a new cat, and it fixed it.

 

I got the same code, just reset it about a month ago, hasn't come back. I'm not worried.

 

well if it is the o2 sensor there is one before adn after the cat. all you need is a 7/8 wrench not sure what it is in metric unscrew it, then un clip the plug and vise versa to install. if it is the cat, take it off, 5 bolts, and put a new one on your self its easy
