1988 chevy camaro 2.8
I replaced the oxigen sensor just to improve chances of passing smog check. But now I have the check engine light on, and the code is code 13 wich is oxigen sensor related. I do not undertand why? before there was not check engine light. I don't unsderstend what may ve happed . Need your your help
If this is an aftermarket O2 sensor it could trigger a fault code.
Yes, it is, a bosh brand, but I think that the old one is too so I am confused. sinse i did not have the code before
