Ok, so I have a bad sensor and I can't find a replacement. The current MAF is a two prong Siemens sensor and I can't find another. Please help! First time Volvo owner and first post! Thanks guys!!

 

never heard of a Siemens MAF. what year is your 940, is it NA or turbo, and if NA, is it Bosch LH 2.4, or Regina injection? Regina uses a MAP not a MAF (eg, air pressure (vacuum), rather than air flow), this MAP is over by the brake booster, and where the MAF would be is instead a air temperature sensor thats stuck into a short tube.

a 1992 940 Regina has manifold air pressure sensor Volvo part number 3517892, and air temperature sensor 1389556



on that drawing, the MAP is part 26, and the air temp sensor is part 25. source of drawing + parts catalog: Volvo Fuel system B230F
