Where is the map sensor on a 2001 Buick Regal Ls
On a 1993 Buick Regal 3.1L, the PCV valve is located on the intake manifold. It is situated underneath the MAP sensor.
Trouble code P0108 means: MAP Sensor Circuit High Input
I have the same issue it is the map sensor
Don't think yours will have a MAP sensor. It will have a MAF sensor, and it is attached to the air filter housing.
After consulting several sources, someone finally called a local Buick dealer who informed me that a 1990 LeSabre does NOT have a map sensor, it was the Mass Air Flow sensor that needs replacing.
The 2001 Ford Ranger 4.0 liter V-6 engine map sensor is located on the firewall in the engine compartment. The map sensor will be on the drivers side of the firewall.
The MAP sensor is mounted at the rear of the left-bank (front) cylinder head.
Powertrain Control Module (PCM)
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.
my 1995 buick regal is starting to do it too but mainly when going uphill or accelerating hope someone answeers soonAnswerI am not sure if this is the same problem, but my 95 regal had what I would call a "surging" or stuttering problem...This was supposedly caused by a spark plug wire shorting out at the boot thus causing a missfire... AnswerMy 1995 Buick Regal was doing this. Mine was a transmission problem. I didn't need a whole new transmission, but I did need to replace the lines because they were leaking fluid. You should definitely get it checked out. AnswerJust had my 2002 into a Transmission shop. The brake switch needed adjusting. I had no check engine light. You might want to get the brake switch checked. Check the map sensor. Mine was doing that, and after having trans check and several parts replaced on it, it ended up being the map sensor
