Re: Where is the MAP sensor? 850 95

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.
