Q: Oxygen sensor problem

asked by on January 18, 2017

I recently paid $80 for a check engine light inspection from one of your mechanics he basically told me what the technicians at auto zone told me which was that the problem is with the variable valve timing solenoid he checked my solenoids and said they were fine. He also recommended that i get a new cat converter too but he said i would still be able to pass a smog. So i go for a smog check today and i dont pass they tell me i need an oxygen sensor and they bring up my check engine light code. Could it be the oxygen sensor causing my check engine light to be on ?

My car has 106100 miles.
My car has an automatic transmission.
