This Acceleration Sensor didnt improve my automotive brake system at all. i was disappointed in its lack of performance and felt like I wasted money on it... It's small and easily misplaced, which was a downside. The only pro I can think of is that it's easy to install..
Pros
Accurately measures acceleration for improved vehicle performance.
Cons
Requires professional installation and may require additional electrical connectors.
I have a 1996 Mercury Sable with AX4N transmission. Shifting from first to second gear was a big problem. I scanned the car's computer system and got a code to replace the accelerometer speed sensor. Since I replaced the old part with a Motorcraft DY935, the gearbox has been working perfectly.
