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!
