On the 1995 ford Aerostar, the speed sensor is located on top of the differential. It is a magnetic style, mounted close to the input shaft.
The speed sensor is located on the rear axle, and is driven by an exciter ring on the carrier which your rear end gears are attached to.
The 1997 Ford Aerostar oxygen sensor is screwed into the exhaust pipe. It is about even with the rear of the oil pan.
which year model, what transmission do you have, and which speed sensor are we talking about?
It appears that the Ford Aerostar with 3.0 engine does not have a crank position sensor, but the 4.0 engine does have one.
