Best Answer

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.

Where is the Pcv valve located on a 1998 Buick regal?

On the passengers' side of the car you'll have to lift the plastic cover over the engine and look at the MAP sensor located at the passengers' end of the plastic cover (black in color and held in place by plastic clips--making up the entire MAP sensor assembly). There are three wires connected to the MAP sensor. Remove the wire assembly first. The MAP sensor is removed by twisting it counter clockwise (a small pair of channel locks might assist in removing it). There is a large spring just under the MAP sensor that pushes down on the PCV valve. Remove the MAP sensor and spring and then you can access the PCV valve. You might need a pair of plyers to remove the PCV valve. Installation of the MAP sensor assembly is done by replacing the spring, putting the MAP sensor assembly on the spring, assure the assembly is in the counterclockwise position and twisting it clockwise to reinstall.
