We own a 99 Ford Ranger with around 80k miles. Yesterday, the ABS light came on, and later in the day was followed by assorted problems. The speedometer is not working below 40 miles an hour, and the overdrive is kicking in and out, causing the vehicle to jerk on the road. I am almost certain the problem will be a sensor, but am uncertain as to which one. I have contacted local auto parts stores and none have a machine to check ABS codes. It's the weekend, and we can't take this vehicle to a mechanic (even if we wanted to spend the extra bucks) and I'm looking for a realiable way to find which sensor needs to be replaced. The weather is poor and doesn't show any signs of letting up soon, and the truck isn't safe to drive on wet roads.

Try a visual inspection of the front wheel sensors and the rear differential sensor.

If that doesn't turn anything up the problem could also be a short in any one of a number of wires and more. Getting the codes read are your best bet.

Good luck and let us know. :)

Suggested Repair

Visually inspect the front wheel speed sensors and the rear differential sensor. If nothing is found, have the ABS codes read, since a wiring short is also possible.

Conversation Summary

A 1999 Ford Ranger with about 80,000 miles developed an ABS light, a speedometer that does not work below 40 mph, and overdrive that engages and disengages, causing jerking. The owner suspected a sensor but could not get ABS codes read locally. The expert advised inspecting the front wheel sensors and rear differential sensor, and said reading the codes is the best next step if inspection finds nothing.
