Hello Everyone,
First off, thanks so much to this community, its places like this one and a couple others that have kept my Volvo running.
Short story, I think the details are important on this one, so please forgive me.
I'm running a 03, S40 with 186K on the dial. Car has been mechanically going great with the engine, I had zero issues....until the incident. I have been fixing it myself for the last 120K, but this problem has stumped me.
I was on my way home from work and went over the classic pot hole, which resulted in my exhaust pipe breaking in half. Due to my location at the time I was able to pull over immediately and see what happened, but couldn't stop where I was for long. I had to take it another half mile before I could really deal with it. The pipe broke after the second catalytic convertor, solidly under the drivers seat. I think this is important because the car still drove fine, all-be-it very loud now.
Before I fixed anything, the next day I turned it on again, and the CEL was on. I snickered because there was obviously an issue.
One complete exhaust system later (I stopped at the O2 Sensor and first catalytic convertor, Convertor original, O2 sensor about 8 years old)....CEL still on.
I pull the code and its a P0015. My understanding is this has absolutely nothing to do with an exhaust leak (Please correct me if I am wrong).
I cleared it, drove another ~100 miles over 2-3 trips for a week....no problems, felt like a new car!.
Trip 5, CEL back on....same code.
I noticed during the cold start that the RPMs were normal, but then creeped up to above normal. I thought this might be an important symptom.
Do I have to drop another Benjamin on a new sensor? Pretty sure its original.
I'm up to date on oil, filters, plugs, belts etc.
Any thoughts are appreciated.
