I have a 2000 Xterra. The abs light has been coming on for a year now. I have took it to a mechanic and replaced the sensors, abs computer system and the light continues to come on. The light will be off for a while but then comes back on and sometimes makes a vibrating noise and the pedal feels like sand. The mechanic and dealer cannot figure out what the problem is.

SOURCE: I have a 01 Terrano and the ABS sensor lights

The ABS sensors on my Terrano are a magnetic pick-up, which senses the passing of the teeth machined into a steel disk on each wheel.
If the ABS computer codes are indicating the G sensor, then that is probably what is at fault. The G force sensor is usually located between the front seats, under the rear of the center console (probably a metal box a little larger than a box of matches). The purpose of the G sensor, is to sense how slippery the road surface is. If you brake on good sealed road, the deceleration G forces are much higher, than if you brake on loose gravel - even if all four wheels were to lock up, the G force sensor still registers the vehicles movement, and tells the computer to ease off on the brakes, as the vehicle is still moving, despite all four wheels having stopped.
