This sensor for your 1989-93 Ford Mustang 5.0L is commonly referred to as the BAP sensor (Barometric Air Pressure). Located on the Fox Body firewall behind the intake manifold, it provides manifold vacuum readings to the PCM to adjust air/fuel ratios. These sensors can go bad over time, replace yours today with this high quality sensor!
Just a quick note to say what great people (Eddie Davis) are at Latemodel Restoration. I ordered and bought a set of Track Pack Wheels for my 2014 Mustang GT.Their prices and service is the BEST in the MUSTANG INDUSTRY, not only the price and service but the honesty. The wheels came thru with the wrong center caps one call to Eddie Davis corrected the situation in one phone call and the next day I had the center caps (FORD RACING) the correct ones no BS, they just did the Right Thing,whereas in this Day and Age you don't here that often. LATEMODEL RESTORATION is the only place for your Mustangs parts and equipment, trust me try them and you will see what I mean!!
