Spectra Premium MA157 mass air flow sensor for the 1986-1989 Chevrolet Camaro V8 5.0L, the 1987-1989 Camaro V8 5.7L and other vehicles measures the air entering the engine and reports it to the engine computer.
A failing sensor can show up as a rough idle, hesitation under acceleration or a lit check engine light. These signs alone do not prove the sensor is at fault; a vacuum leak is another common source.
It fits the 1986-1989 Chevrolet Camaro V8 5.0L, the 1987-1989 Camaro V8 5.7L, the 1986-1992 Pontiac Firebird V8 5.0L, the 1987-1992 Firebird V8 5.7L and the 1985-1989 Chevrolet Corvette V8 5.7L. The listing is a single sensor, which is the quantity a car takes.
Is MA157 a Chevrolet Camaro mass air flow sensor for the 1986-1989 Camaro V8 5.0L?
Yes. Spectra Premium MA157 fits the 1986-1989 Chevrolet Camaro V8 5.0L, and that engine takes one sensor.
Is this Corvette mass air flow sensor the right one for a 1985-1989 Chevrolet Corvette V8 5.7L?
Yes. Spectra Premium MA157 fits the 1985-1989 Chevrolet Corvette V8 5.7L, which takes one sensor.
Can a faulty Spectra Premium mass air flow sensor turn on the check engine light?
Yes, it can: the engine computer relies on the sensor's air reading, so a bad reading can set a code. A shop can scan the code and test the sensor.
Is the MA157 sold as a single sensor?
Yes. This Spectra Premium MA157 listing is one mass air flow sensor, and each engine it fits takes one.
What can I look at on a mass air flow sensor myself?
With the engine off and cool, check the connector and wiring for damage, loose fit or corrosion. Testing the sensor's readings is a job for a shop.
