Manifold absolute pressure and manifold absolute temperature. The Map sensor is ususally on the fire wall and has a vacuum line going to it and three wires. The Mat sensor is on the intake manifold or air intake and looks like a coolant temp sender with two wires. Jules, Automotive lecturer. Australia.

Answer 3

The MAP sensor is placed on the brink of the intake in between the firewall and the valve disguise of this motor. i might hesistate to swap it even although. i became a GM mechanic for years and that i've got purely replaced a pair of those sensors touching directly to their operation. a lot of those I replaced by using actual harm. instead those sensors many times sign up a subject it particularly is concerning a vacuum leak or a misfire of a few variety. additionally you've got a bad connection to it, yet a lot greater possibly a chop up hose interior the vacuum furnish to it. Recheck all the motor stuff earlier dropping your funds on changing a sensor which in all liklihood continues to be ok. good success.

Answer 4

MAP=manifold absolute pressure
MAT=manifold air temp

Occasionally the emission sticker under the hood will diagram where these components are. I would suggest going to the local library and using the shop manual (Mitchell, or Haynes.)
