Think of a speed sensor as a small generator. The faster you go the more current it produces. Each wheel speed sensor sends that current to a module and the module monitors them. With the vehicle in motion all the wheel speed sensors should read about the same amount of current. When you hit the brakes hard and one wheel locks up because of ice or whatever the module stops receiving current from that one wheel because it is no longer turning. The module now sends a signal to the abs valve block to relieve the brake pressure to that wheel to allow it to spin again. That wheel begins to spin again and it sends current back to the module. This process happens several times a second until all the wheel speed sensors read the same again.
What else can I help you with?
If the speed sensor is bad will it cause the fuse to burn out for the odimeter?
The odometer gets its signal from the speed sensor, so if the (tailshaft) speed sensor is bad then the odometer obviously will not work
What would make your speed odometer not work?
Bad speed sensor is a likely culprit
What happens if the speed sensor is broken?
If the speed sensor is broken several things can happen. The speedometer will not work and the transmission may not shift correctly.
Can you take out the speed sensor in a car and the car still work?
yes
Why the speedometer doesnt work on a 1989 astro van after replacing the speed sensor does has more than one sensor?
check for a faulty speed buffer module
Would the speed odometer work if the speed sensor is bad?
No, I had that same problem with my 1999 Dodge Ram and it did not work till i replaced the speed senser on the trany. Rick
When the speedometer doesn't work how do you fix it?
did you check the speed sensor on the side of the transmission?
Why does the speedometer on 2003 Hyundai Santa Fe not work?
Output speed sensor
Why wont transmission shift out of first on 96 dodge caravan and peedometer does not work?
The speed sensor sends a signal to the speedometer to show the correct speed and it sends a signal to the transmission telling when to shift. If the speed sensor is bad the speedometer will not work and the transmission will not shift correctly.
Is a transmission range sensor the same as a transmission speed sensor?
No, the range sensor reads what gear or "range" you have shifted into.A speed sensor reads the speed of an item.No, the range sensor reads what gear or "range" you have shifted into.A speed sensor reads the speed of an item.
Speedometer stop working on 97 eagle talon?
What happens with the speedometer is that the speed sensr wares down and has to be replaced. The speed sensor is located to the back of the engine. Take the clip off, then take a 10mm socket and take the bolt holding the speed sensor to the engine off. Then replace the sensor with a new one bolt it into place. Put the clip back on and it should work. The speed sensor is one of the main reasons why it doesnt work.
Where is the speed sensor wire located on a 2000 infiniti i30?
The speed sensor wire is connected to the speed sensor and goes to the speed sensor relay switch. The speed sensor relay switch is connected to the computer by a separate wire.
