Just got my car back from the dealership, pulled out onto the road and didn't get more than 2 miles down the road and a CEL comes on. I read it with my ScanGauge and it told me it was an O2 sensor. When I pulled into the dealership the guy told me there was no way it was related to the work I just had done (timing belt and oil pump) which is correct, but I'm thinking since they had to disconnect the engine from the exhaust/trans to work on it, they probably forgot to plug something in. So I left the car there overnight for them to take a look at it in the morning and got another rental for the night (my 3rd in 4 nights). I swear, if my O2 sensor really went south and I have to replace that, I'm going to lose it

I remember hearing on Car Talk the three most powerful words to use at a repair shop: EVER SINCE YOU ...

They switched yours for a broken one during the visit.

They're also the most often misused. People just have to have someone to blame when their machines break. We like to joke "Ever since you guys replaced my wiper blades, my engine fell out."

I had this happen to me after doing the same job on a friend's Impreza. I always scan post-repairs, and there was no code on my road test, but the next day the CEL came on. Turns out I had inadvertently tugged one of the 02s connectors during disassembly, just enough to cause an intermittent poor contact. Of course it may be a coincidence, but shit happens.

Well, it has to make sense, agreed. But the facts presented here point to the shop that fixed it. Res ipsa loquitor.

I'm not saying that my rear wheel bearing failed ever since they worked on the engine, but it's a sensor that's located in the exhaust (which was disconnected). Coincidence? Could be, but I didn't have the issue when my car went into the shop.

I suggest not doing that. It will do nothing but piss of your tech. If you use those words and it is his fault, you gain nothing but an irritated technician. If you use those words and its not his fault you may gain a higher bill and an irritated technician. If you don't use those words and its his fault, he will take responsibility if he's not a crook. If you still suspect it was his fault, tell him not to fix anything then go get a second opinion and let the new guy know the whole story. You can ASK if the technician thinks the new problem may be related, but don't come in basically stating that the technician messed up. That will never do you any good. We have no qualms with helping you better understand what's going on and how your car works, especially if it will benefit our reputation (most of us anyways).

If you have the means, work on it yourself. Then blame yourself when you mess up. Works better (less blame) and saves a lot of cash for more repairs (more blame).

I fully intend on doing the o2 sensor since that's something I can do with hand tools. I was just upset that a CEL mysteriously appeared as soon as I left the dealership

Absolutely, I shared my nearly identical Subaru story for that reason.
