#54 of 57 1998 Buick Lesabre MAP Sensor Voltage by Schmegalhof Feb 06, 2009 (5:20 am)
I have the "Check Engine" light staying on. I had it scanned and it came up with the MAP sensor. I check the voltage from the positive terminal of the harness connector to ground and it reads 11.5 Volts. Should this voltage be closer to 4-6 volts like it says in the 1995 Buick Service Manual or did they increase the voltage on the 1998 model? If it should be 4-6 volts does anyone have an idea of what might be the problem? Does it mean that the PCM is bad and needs to be replaced?   Thanks, Schmegalhof

#56 of 57 Re: 1998 Buick 3800 Motor Check Eng Light [Sizzlerdon] by magm66 Apr 26, 2009 (7:35 am)
Replying to: Sizzlerdon (Dec 16, 2008 1:34 pm) I have the very same problem. I have changed, TPS, MAP, MAF, EGR, fuel pressure regulator, spark plugs, wires, plenum, lower intake gaskets, PCV, coils. My ignition module was checked at Autozone and turned OK. Compression reads 195, 190, 190, 190, 190, 200. I wonder if I may have a broken valve spring or faulty knock, crank, or cam sensor, Did you find the problem on yours? Thanks.
