My "check engine" light came on, and when I checked the error codes (1-2-1), Haynes says this means
                      the MAP sensor - but doesn't tell me where it is! Can anyone shed some light on this?

                      Also, when I went to the local Volvo dealer to get a new Flame Trap, they told me they are no longer
                      recommending replacement. Is this true?

                      Thanks in advance.

                      The dealer I work at has been told if the vechicle had a flame trap, then replace it, if there was no flame
                      trap then leave it out. The 1998 on have the flame trap left out.

                      Your MAP, Mass Air Flow Sensor is located on the Air filter box. The hose that goes from your airbox
                      to the throttle, the end that is at the airbox is the MAP. Try taking the connector off, cleaning it out and
                      then plugging it in and out about 10-15 times to clean up the contacts and then see if that keeps the
                      codes away, if not you may actually need a new sensor.

                      Greg-
                      Technically, your car doesn't have a MAP (Manifold Absolute Pressure) sensor. It has a MAF (Mass
                      Air Flow) sensor. It is located on the air filter box. It has an electrical connector and a hose connected
                      to the throttle body. The other post has a good suggestion in repeatedly plugging/unplugging the
                      connector to clean the terminals on the MAF and connector. A dab of vaseline wouldn't hurt, either. If
                      the code comes back, you probably should replace the MAF. I had an O2 sensor fail on my '93 at
                      about 133K, and shortly after replacing it I set a MAF code. I cleared the code and haven't had it come
                      back for over 7k. On the flame trap, I don't recall seeing anything about eliminating them in any official
                      Volvo info. We still replace them every 30k.

         Dave, I was told to "remove and throw away" the Flame Trap. I did this 2 years ago without
         experiencing any ill effects to the car - didn't catch on fire yet. The logic was, the turbo models don't
         have them so why should the non-turbo need one. Why risk blowing out your rear mail seal if the Flame
         Trap clogs prematurely? I'll bet there are numerous cars out there without Flame Traps. FWIW.
