Walker Products Mass Air Flow Sensor P/N:245-2189
Walker Products 245-1208 mass air flow sensor for the 1994-1995 BMW 850CSi V12 5.6L and other vehicles measures the air entering the engine. Its air flow data helps the ECU set the air-fuel mix for fuel efficiency and performance.
A failing mass air flow sensor can show up as a rough idle, hesitation or a check engine light. These signs alone do not prove the sensor is at fault, since a vacuum leak is another common cause. This listing is one sensor, and the 1994-1995 BMW 850CSi V12 5.6L takes two.
This mass air flow sensor assembly also fits the 1988-1994 BMW 750iL V12 5.0L and the 1993-1994 BMW 850Ci V12 5.0L. If your BMW is not named here, look up its year and engine in the "Vehicles it fits" section.
