Speedometer doesnt work. PLEASE HELP
Hello, I have a 1999 Ranger 3.0 2wd. THe speedometer stopped working and I was told it was a speed sensor. I read the posts and all, and I removed the sensor on the differential, but it is different from the sensor they gave me. Is there another sensor or did I get the wrong part? Please help I am trying to fix it today. THanks

the one you got gos into the trans via the spedo cabe. That one is driven by a gear then turns a magnet in that sensor to send the signal then the cable goes on to the old speedos wich are affected by a larger magnet and turns the needle.
The new ones are Hall-efect (sp?) sensors.. tht are actiated by a ring that is bolted to the ring gear.
{sorry got toointo it.}

2) Open the large 40-pin connector accessible from under the truck directly below the driver seat. Check it for water or corroded pins.

Bad ABS sensor (common);
Bad speedometer (possible);
Bad GEM/4WABS Module (not likely);
Opens or grounds in the wiring or connectors.
I suggested looking at the 40-pin because it is a known trouble spot and easy to check.

I checked the connecter under the drivers seat and still nothing. It was two different plugs right next to each other was that it? I also checked the whole wiring harness and no rips or anything. Any other Ideas? Is there another speed sensor on there somewhere else? Like possible the one I bought first, can that go somewhere? Thanks.

These are the possibilities:
- Bad ABS sensor;
- Bad speedometer;
- Bad GEM/4WABS Module;
- Loss of power/ground to the Speedometer or GEM/4WABS Module;
- Opens or grounds in the wiring or connectors that connect the above. There are two wires from the diff ABS sensor to the GEM or 4WABS Module. There is a single wire from there to the speedometer.
