Hello!
I just had a fuel induction service done on my 99 Rav4 at an independent shop. When I drove out of the garage and went about a mile, I noticed the engine was struggling and the check engine light came on. Neither of which was happening before. I turned right back around and they spent an hour and a half with the car. Then told me my air fuel ratio sensor had failed at the exact moment I drove away from them. They're swearing up and down that there is NOTHING they could have done that could have POSSIBLY caused this. The showed me the part. It didn't appear to have been recently replaced. I really want to believe them and have them fix it, but the timing is unbelievable. Anybody know enough about the the part that can ease my mind? Thanks in advance!

It sounds like they are talking about an oxygen sensor. The induction cleaning could have damaged it but it usually doesn't.

I've seen F.I. services mess with injectors before, however coincidences happen so don't rule it out.

This was an induction service, not injector cleaning so it went around the injectors, not through them.

Must be a CA emission vehicle to have an A/F sensor. What was the code that was set for the A/F sensor? What did the end of the sensor look like? What is black as the ace of spades?
Have them unplug the A/F sensor to be sure there isn't something else causing the engine to run bad.
Probably just bad timing or the A/F sensor had reached the end of its service life. There is another O2 sensor downstream after the converter. If they were using a chemical that messed up O2 sensors, it would of taken that one out too.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
