will any MAP sensor from any G.M. 4.3 liter engine work on any other G.M.4.3liter engine,or are they type specific?
No. You have to know how many BARS the MAP sensor is rated for the specific year the engine was manufactured. Here’s a link that explains where to check a GM MAP sensor for its BAR rating. http://www.robietherobot.com/storm/mapsensor.htm
