"Have I thought about it, sure, so I looked it up...not permitted. Do I have one installed? Absolutely not, but last week I was installing front end parts a 10 pc kit on my neighbors 2004 Toyota Sienna Van, and proudly right there in both front calipers (that I needed to remove to uninstall and hang up next to the caliper were 2 ABS brake sensors, about the circumference of a nickle, and 1" thick, and low and behold, they are simply wired wheel encoder magnet pickups counting the rotor vanes. A simple wheel encoder already installed on that vehicle stock.

I have no idea if that vehicle is even in the guide, but they are a part of the stock ABS brake system and could easily though illegally be used to determine actual track position accurately as long as it does not do wheelies.. lol.[/QUOTE]

I believe Pontiac used the ABS sensor to trip the Low Tire Pressure light on our 2004 Grand Prix. If one wheel was rotating at a different speed than the other 3 the light came on.
