The MAP sensor measures the Manifold Absolute Pressure or manifold vacuum. The manifold vacuum is a good gauge for your car's computer to tell how much load is on the engine (the more load, the lower the vacuum). By knowing the amount of load on the engine, the computer can then estimate air density and the mass flow rate, which enables the computer to determine the amount of fuel the engine needs.
Most older cars only have a MAP sensor, but on the Eclipse the MAP works as a back up system to the Mass Air Flow (MAF), which uses a heated wire in the engine's cold air intake to determine the amount of air flow to the engine and the engines fuel requirements. On the Eclipse, if the MAF fails for some reason, the MAP takes it's place and the engine is able to function as normal. I believe that the MAP on the Eclipse is also used as a barometric pressure sensor (BARO), which measures the atmospheric pressure, which is necessary for the computer to deliver the correct amount of fuel at different altitudes.

Where is the barometric pressure sensor on a 92 eclipse?
The MAP sensor is located on intake manifold.
Where is the map sensor on a 2003 Mitsubishi eclipse?
Map sensor is located on the hose going from the filter box to the throttle body. There is only one sensor in that area.
Does a 2000 Durango have a MAF sensor or a MAP sensor?
It uses a MAP sensor.It uses a MAP sensor.
Where is the map sensor on a 1999 Mitsubishi eclipse?
Mitsubishi Eclipse's don't have MAP sensors that come stock with the car. Mitsubishi uses MAF( Mass air flow sensors) not Mass air pressure and Intake Air Temps also referred to as speed density.
Where is the knock sensor located on a Mitsubishi eclipse 97?
where is located theknock sensor 97 mitssubishi eclipse
What is a map sensor on a tracer?
a map sensor is a manifold absolute pressure sensor.
Where is the map sensor located on a 1991 Mitsubishi eclipse?
The 2.0L engines do not have a map sensor. The ECU meters intake air through the mass air flow sensor to calculate how much fuel to inject. The 1.8L engines should have a similar setup installed on them but I dont deal in those very often. Hope this helps.
What is a map sensor on a 1990 cutlas and were is it?
if it has a 3.3 there is no map sensor
