Hello and welcome!

How often does this occur?

Always at 55mph?

Do you have access to a scan tool that can retrieve codes from the entire vehicle?

Thanks

William.

Do you have the code numbers so i can look them up? Does the speedometer stop working all together. does the needle go back to 0mph?

Customer: replied 1 year ago.
Don't have code #'s. .speedo goes back to zero and stays there.

A mechanic had replaced power steering pump and rack and pinion unit long with rear wheel bearing just prior to this issue.. He remarked that he had to drop the frame to replace rack+pinion.!

My wife commented that she lost her brakes a few times ...but they kicked in "just in time"
Expert:  Derek Werner replied 1 year ago.

A wheel speed sensor fault can cause abs braking problems at low speeds. When applying the brake pedal a buzzing noise can be heard, this is the abs pump activating. Your mechanic had to remove a major steering component in the vehicle, and could have pulled a wire or left a connector loose. You can return the vehicle to him and have the connections double checked.

Also a common fault with your vehicle is a internal electrical fault in the instrument cluster causing the gauges not to work. The cluster will need to be replaced.

The only way to properly diagnose the problem is to retrieve codes from the engine control module, and the anti lock brake control module.

I have a question for you...If I disconnected one of the abs sensors on one of the wheels..wouldn't it show up instantly on the dashboard rather than waiting until I got up to highway speed?
Expert:  Derek Werner replied 1 year ago.

Yes you are correct, if there is a open in one of the wheel speed sensor circuits it will turn on the abs light when the key is in the on position. With a scan tool this will show up as a current fault code.

If there is a poor connection for the abs wheel speed sensor circuit this will show up under driving conditions and will be a intermittent problem.
