If the speedometer on a 93 Ford F150 has failed is it the speed sensor the fuse or a loose wire?

You should still have a mechanical speedometer. Near the back of your transmission is a cable going into the tailshaft. Unbolt the retaining clip and slide the gear out of the tranny. Inspect it for broken/missing teeth. You can obtain a replacement at any parts store, just know your engine/trans type and your rear end gear ratio. It could also be a bad ground at the speedometer itself.

There are several possibilities why the speedometer is not working. The VSS, vehicle speed sensor may have failed or become unplugged. The speedometer may have failed, or the ECM, engine control module, may have failed or there could also be wiring issues.

The 1987 Celebrity uses an electronic speedometer. There is a VSS(vehicle speed sensor) on the trans-axle that could have failed. The speedometer itself may have failed, the ECM (engine control module "computer") may have failed or there could be wiring issues.

There is no speedometer cable. MPH is calibrated using a speed sensor. If your speedometer is not working, you have a bad speed sensor module.

Possible failed rear axle speed sensor. This truck does not use a cable, the speed signal comes from the ABS.
