I had a check engine light indicating faulty catalytic converter, O2 sensor or other emissions related problem. The shop said the catalytic converter and o2 sensor was faulty so I replaced both, using a universal catalytic converter. After a week, the check engine light came back on and has stayed on, with the same code as before. I took the car in for an emissions test, which it passed with flying colors despite the light remaining on with the original fault code.
why do I get this check engine light and code when it passed the emissions test and what do you suggest I do to get rid of the light?.
