whats going wrong? this started about 3 weeks ago and is getting worse and worse. the abs and brake light will both randomly turn on and stay on. if i restart the truck they turn off. the other day when they came on i decided to test the abs system...when the lights are on abs does not work, but when they are off everything is fine.

a buddy at the dealership said speed sensor but he's just a parts guy what do yall think?

 

it is the speed senso.
i have the same problem.

 

tx i would check the code beforeyou go changing parts, it could be a bad ground or something stupid

 

there is a recall on this propblem! and yes its the speed sensor

 

theres no service light grumpy. where are the speed sensors at? any clue on how much it costs? ill do it myself before i take it to the dealership for 2 days to let some yahoo poke around my truck....unless its extreemly expensive lol.

 

You may not need to change any parts. First each front wheel sensor out and clean them. I had the same problem and the front sensors only needed cleaned.

 

where are the sensors? what do they look like? im clueless lol. never had to mess with the speed sensors.

 

pull the front rotors off and there is an allen head bolt that screws into the hub. you could try and pull them out and clean the mounting surface that may help. oh when you put it back together put some wheel bearing grease on the sensor

 

thanks a ton...im guna try cleaning everything before i buy anything new
