The best way to find out is go to your local auto parts store, ask for a haynes or chiltons manual on your vehicle. This will tell you everything you need to know about working on your vehicle. It is located near the intake manifold, it monitors manifold pressure. If it's the 3.1L engine, it's mounted to the rear of the intake manifold between the engine and the firewall of the vehicle. If you have a code setting for the map sensor, make sure the plastic lines that go to the sensor are not broken or disconnected first before buying any parts.
I have the same issue it is the map sensor
Where is the map sensor on a 2001 Buick Regal Ls
The map sensor on a 1991 cavalier is on the passenger side firewall towards the top.
where the map sensor on 98 blazer?
The map sensor for the 1991 Acura Legend is mounted on the firewall. It is in a box near the factory strut brace.
The 1991 Corolla does not use a MAF sensor - it is MAP based.
On a 1993 Buick Regal 3.1L, the PCV valve is located on the intake manifold. It is situated underneath the MAP sensor.
its on the firewall above the intake manifold
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.
Where is the choke sensor on a 1991 Oldsmobile ciera 3.3L
Should be by the alternator in the back
Trouble code P0108 means: MAP Sensor Circuit High Input
