Hello -

I have a 92 240, B230F engine, and the "check engine light" is on.
I just had the throttle body cleaned, timing belt+tensioner replaced, new thermostat and an oil change.
The car is running great, maybe a little rough idling/cold start up, but not really outside the ordinary.
I tried to check the computer but I'm not getting any response from the LED (no light at all).
Any suggestions wouuld be greatly appreciated.

Thanks!!!

Patrick

I have a similar problem after having just a little rougher starting after blowing out a fuse for my someday new radio....(switching cd/radios can be a pain in volvos..). And a hole in my muffler?

anyway my local Volvo mechanic says if my car is running well enough and the check engine light is on it's most likely the Oxygen Sensor is wearing out. It's on the side of our exhaust manifolds...I have an older junker that I'll pull one out of to see if I can switch it...otherwise they're a bit expensive... 60 to 90 dollar range.

I have a 93 240 , the check engine light is on, the codes from OBD indicated 2-3-2 fuel mixture too rich or too lean at idle, according to the book, with this code and diagnosis, check engine light is supposed to be off. Let me know how you make out with this. By the way, are you leaving the ignition key in the "on" postion with the engine not running when you check the OBD?

I cleared the check engine light by disconnecting the battery. Will drive it a while and see if it comes back on.
