ABS Light

[Ralph Edward]

Need help on ABS light and brake light stay on all the time. Did search and others have had the same problem but no answer on how they fixed it. Any help will be greatley appreciated.

I fixed mine by replaceing the Rear Wheel Speed Sensor located on top of the differential. My truck is a 98. 5 24v and required part #1-05014787AA This part includes a short extension wire leade because the connector for the wire on the new part is located on the opposite side of sensor. Cost me $38 bucks, I believe.



Simple and very easy to replace by removeing the one bolt. One thing I did was clean the area with carb cleaner before removing so crud would not fall down into the differential. Also, I put a little grease on the O-Ring before installing the new one.

Changed my rear wheel sensor today. Fixed my problem. The old one measured 0 ohms and the new one reads 2100 ohms (uncalibrated meter). Dealer wanted $185 just to do a scan to determine which sensor was defective.

Sounds like you need to find another dealer. When the one on my sons truck went out I went by dealer to have them check it(no charge,only took them a couple minutes)It showed bad so I got another one and we replaced it. Ole one broke off but we were able to get piece out. His went out after he went to bigger tires.

The left front wheel speed sensor was the problem for me. The wires had chafed through.

Idiot brake lites

Had the same problem with ABS & Brake warning lites staying on. Also, my speedo was not registering until the truck reached 25mph.

I have a post on this site with several suggested fixes by others. I tried most of them with no luck. Then I saw the post here about the speed sensor, pulled mine and checked it with an ohm meter. Indicated "open", as in open winding in the coil of the sensor. I bought a new one from Keating Dodge in Winnie, TX for $33 and change, changed it and everything works OK.

Hi.



Just experienced the same problem (ABS light, Brake light and speedo not working). . went to the dealer (still under warranty) told the service guy that he should check the rear wheel sensor (according to this discussion forum), he did and ... sure enough is was opened...



The dealer will replace it tomorrow morning.



You really save me time (it took less that 30 min) for the diagnostic !!



Thanks guys.
