91 240 Wagon Check Engine Light 200

I have a 1991 240 wagon, owned since new. We like the car. My wife drives it. Great visibility and all that stuff. I have taken care of it with regular service, etc. As with all of these cars, the check engine light continues to come on. My mechanics comes up with this and that, cleans this and that, adjusts this and that but it won't stay out. My wife is pissed. She doesn't like seeing that light come on. To my knowledge, nothing associated with it has ever amounted to anything. How about I just put it to bed forever (the light). We lived without them before.

Thanks,

Steve

    Read the OBD codes and let us know what that connector on the inside of the driver side fender says. Without that, advice will just be general. Although 240s don't suffer of fried valves like the 5 cylinder engines of later models, the valves burn due to owners ignoring the check engine light.

      I've been an 850 owner for over 3 years and not once have I heard of a white block with fried valves.

      Those engines are very robust so it must have been a case of owner neglect...

      No engine is perfect. Not even the red blocks. I remember a former boss telling me that his friend had to rebuild the head of his 240 at about 100K. Sh.t happens...

    I have to agree, use the OBD on the drivers fenderwell and get the codes. If its a problem that is fixed but the code won't go away after you reset the OBD then you might as well pull the dash and remove the bulb. Don't forget the electrical tape over the hole or you will have a ghost light. I know this because I live with a picky woman. She threw a major when I took out her closck and put a tach in its place. "But honey you wear a wrist watch" No matter had to install a little clock next to the radio,

    See the faq for how to retrieve the codes from the OBD system: http://www.brickboard.com/FAQ/700-900/EngineOBDCodes.htm

    Once you find out what codes are being set, post back with the numbers and people can suggest things you should investigate.

      The computer in my 90 still remembers the code for a bad intake manifold gasket that was repaired about 3 years ago. I was constantly pulling the battery cables off, but eventually the light would come back on. However in a recent post there was a suggestion to pull the #6 fuse (I believe it is #6 but please do a search to verify) and that will fix it. Don't know if this works since my car was recently sold, but it is certainly worth a try.....:)

    I don't know Steve. It kinda looks like you are asking how to do what your mechanic won't do -- pull the bulb.

    Many of us drive 240's of that vintage without CEL hell, so it is possible to fix properly, once and for all, and not a characteristic of the model/year as you imply. Proper diagnosis and repair. A mechanic who will consult with experts and not limit herself to what she already knows.

    What do you think should be done?

      Thanks for all the replies. I appreciate it. Art, I'm not sure actually. My Volvo store is owned by the former service manager for the dealership. I assume he knows what he is doing. But, he can't seem to stop or fix this issue. It seems to be one thing after another. It is always some BS sensor or something that he doesn't seem to think is important. However, the damn thing won't stay turned off and this has been going on for about three years. My wife is tired of it and I'm tired of her complaining about it, not to mention spending all the money for nothing. I'm thinking at this point in the car's life, turn the damn thing off and take my chances??????

      It is very frustrating. I have the same problem with my V70. The electronic throttle body light comes on all the time. It has been replaced under warranty. The dealer says "they do that." No symptoms at all. I think the check engine light thing is just a huge scam. I'm 62 and everything was fine when we didn't have them, right??????

      I've never burned up an engine in my life.

      Steve
