T5wagon1717 Posted April 25, 2011 Report Share Posted April 25, 2011 Hey. So car threw an engine light yesterday. Took it to get the code pulled, and it said no codes..... I know the smog computer cannot connect to the Ipd tunes, but can obdii scanners? Car is running fine, I don't notice anything bad but I would like to make sure it's all ok, Thanks Link to comment Share on other sites More sharing options...

FCP Euro Posted April 26, 2011 Report Share Posted April 26, 2011 I had this issue on my 850 and it ended up being a bad connector. Being the car had OBDI and OBDII, I just used the box under the hood and called it a day. Also, one thing to consider, the CEL could be for a computer that the OTC Scanner cannot read.

AverageVolvo Posted April 26, 2011 Report Share Posted April 26, 2011 Only the 94/95 and the Manual tunes on 850's don't have Obd2 as it did not exist. Their automatic tunes are 100% Obd2 compliant. As suggested check the fuse. Link to comment Share on other sites More sharing options...

Mesoam Posted April 26, 2011 Report Share Posted April 26, 2011 I had this happen randomly after doing some troubleshooting with regard to cap/rotor work. I had only been driving the car around town, after i took it on a highway cruise, CEL shut off and has not re-appeared (no the bulb didn't burn out). We had been trying/replacing so many different parts I just figured it was a fluke from all the swapping around. And, Gabe 94/5's have the port but OBD2 standard was not enforced until 96, volvo was simply ahead of the game B) Link to comment Share on other sites More sharing options...

I love when I ask Autozone to get my codes pulled and they almost won't because they're too busy trying to convince me my car doesn't have OBD2. :lol: Link to comment Share on other sites More sharing options...
T5wagon1717 Posted April 27, 2011 Author Report Share Posted April 27, 2011 So, went to an independent shop with a Volvo scan tool and they did it for free. It was 2-3-2 long term fuel trim idling. Guess look for a vacuum leak. Anyone familiar with te code? Link to comment Share on other sites More sharing options...

But on the Stock Ecu there is definitely no Obd2. It has the port but no access. MAYBE a 96+ ecu/tune ina 94+ rectifies this??? That's why 94-95 have the Led boxes under the hood. Likewise the 850 manual tunes don't have Obd2 as Europe was slightly behind USA> standards on Obd2 So 94-95 easy . 96-97 smog issues for lack of Obd2 connectivity I have tried to use my Obd2 on several 94's with no prevail. SOME late model 95's have Obd2 Link to comment Share on other sites More sharing options...

I didn't mean for it to sound mean or anything, I just thought you would have known that, since they do have OBDII. And that's not correct. My 94 850 had a stock ECU and I have pulled codes off of it many times using the OBDII port. It has access to the stored codes on the ECU.The only reason I don't use it anymore is because I had a manual tune and obviously those have no OBDII. My Dad also had pulled codes off of this car LONG before I was even able to drive. Link to comment Share on other sites More sharing options...

Maybe the port works on turbo cars and not the NA cars? Link to comment Share on other sites More sharing options...
