Very professional, polite, and informative. Went in with check engine sign. Did a evaluation and there was one sensor that is broken. They informed me that there are three sensors. It's only giving me a problem with one of them. I have lots of mileage and plan to drive for couple more years. They recommended just to fix one for now, because it's an expensive parts. But the final decision is up to me.
I decided just to fix one, knowing I could have issue later. They diagnosed, found the exact problem, recommended, and I made the final decision.
