Yeah, we did clear it, but it came back on. The light also goes off once in a while on it's own. Thanks

Hi, new here and to my toyota. I just got this car from my uncle and need to smog it. The code P1133 came up and I know it lists as the A/F sensor circuit responce. Now, where is it, and what do I look for? It would be cheaper if I can fix it istead of the smog shop. It is a 97 Camry California car with a 4 banger and auto.
