The MAP sensor measures air flow for your car's computer. The computer uses air flow to set fuel flow for the correct fuel/air mixture.
The location of the map sensor depends on what year of which model car you are asking about.
The MAP sensor is on top of the throttle body. as you are looking at the engine from the front of the car, it is on the right side of the engine. The sensor says "MAP Sensor" on the top of it. very convenient.
It doesn't use a Map sensor , it use a MAF sensor , and it is located right on top of the Air filter box
On the firewall on the right side. if the car is 3.3l v6 then the car doesn't have a map sensor but it does have a mass air flow sensor the code is the same for both of them only a 2.3 has the map sensor so don't be fooled by this by code 34 the chilton book is very helpful
The 91 has the 4.6L engine and has a MAF sensor located just after the air filter box so it has no MAP sensor.
no need for map sensor enhancers on cars before 1996...
The MAP sensor ( Manifold Absolute Pressure sensor) sends the correct internal pressure to the ECU for the proper fuel/air mixture.
It will kick on the check engine light and the car won't go into closed loop
change the map sensor
Australian E series Falcon
It uses a MAP sensor.It uses a MAP sensor.
It sounds like the MAP sensor is bad. Make sure there is no cracks or holes in the vacuum line and if it is fine, replace the MAP sensor.
