Rear Abs Sensors.. How They Work? Voltage Ranges?

[GreeceS13]

Can anyone help me with the rear abs sensors?

How they work?

Each sensor have 2 wires!

What voltage they need to work and how they work?

What signal send to the ecu?

What the difference if the the gear that reads speed is larger? (S13 smaller than GTR gears )!

To be more specially.

S13 diff has one rear abs sensor in the driveshaft..

GTR diff has two rear abs sensors in the axles..

I want like crazy my car to have ABS! I will not drive it without abs!! So please help me to make it work!

I think to put one abs sensor in one of the rear gtr axles!

But as I said gtr gears has larger abs gear.. so which abs sensor to fit? S13? GTR?

Any other idea!

Please don't say me to don't use abs!

just use the s14 diff housing!

If not....abs sensor sends a speed by the number of times it pulses per second. The gtr senders as the axles will give a very different reading to the s14 driveshaft reading because the diff has a 4:1 (ish) ratio. The abs computer must expect one or the other signal (ie before diff ratio or after).

also, r33 gtst also uses 3 channel abs like the s14 so you may be able to use a 33 gtst diff
