check engine light

The "service" light has come on (lower right corner of dash) and the wonderful mechanic says it would be 240.00 to find out what it means... anybody know of a reasonable way to find out what the computer is telling me?

Tell your $240 mechanic to go f**k himself.

That's robbery.

IF IT'S THE CHECK ENGINE LIGHT
You can check the code(s) for free by yourself. Go to the "Volvo Repair Database" dropdown near the top of this page and go to the 850 section and release on "How to check codes '93-'95"

Or go to the 850 page using the navigation at page top and look for the same link there.

or just go to ebay and buy one of those OBD II scanner to read the code~

Sorry JC but the 94 was an OBD I system... Matthew had the best answer once again, and he also showed where to look for the various codes.

Hi Matt - '94 850 wagon, I tried to clear the CE code using the instructions I found on this site:

but even after several tries it didn't work. Any ideas why?

Yup. To clear the codes, you must read all of them (get to the point that the first code is repeated) first.

An insider tip: If a mechanic tells you some outrageous price for a service that we all know doesn't cost anywhere near that much, chances are that he doesn't feel like working on it, he doesn't like you, or he's just trying to rip you off. This is also what some mechanics will do if they don't know how to fix a problem. They suggest that it's part X and it'll cost $2000 to replace, at which point, most customers just say "forget about it". Whatever the case, it's best to find a new mechanic or be your own mechanic

Thanks, White - okay I'm new at this - how do I clear the codes? I've read about clearing ignition codes and fuel sensor codes on this site, but not a general clearing. Maybe they're the same. Could you humor an old man and tell me how?
Thanks again!

Yes, it's the same thing as clearing your engine/fuel system codes, etc.

Before going to the volvo dealer, it's interesting to know why the check engine light is on. Usually, there is absolultly no reason for it to be on.
It has been at least 3 times on my S70 that has know 120 000 miles on the clock and each time the volvo dealer just reset the system because there was no problem.
