I have an Auto X Ray OBD1 scanner model 10110.
I use this scanner on two cars,1986 Corvette and 1986 Camaro. I have a 1988 Camaro prom chip in both cars, 86 Camaro because of engine change to 350, 86 Corvette to delete the V.A.T.S.
Scanner shows 41 data displays, #25 is MAP sensor, what is the scanner reading, these cars don't have MAP sensors they are both MAF type systems.
I contacted Auto X Ray and so far they haven't been able to answer what it's reading, can you help ?

This code is not a MAP it is MAT sensor signal voltage low. This is a manifold air temp sensor. So you need to look for a short in the signal wire that provides the 5 volt to it. Hope this helps if you have any other questions just ask. Have a great day.
