So my ABS light came on last week. I want to the auto parts store and the codes said rear center ABS sensor. I purchased and replaced, but the light stays on. I have checked the wires and take my truck back to auto store to clear codes. The light goes off and the first time i brake it shudders and the light comes right back on. After that the truck drives and stops fine but I cant get that light off. Any ideas?? It driving me nuts!!!

 

Rear center ??

 

Its the one that sits on top of the differential

 

Thought that was a speed sensor

 

same thing....but it causes the ABS light to come on

 

Anybody have any ideas???

 

How did you check the wires? Did you check them all the way to the PCM? Have you had a scanner on it and see if the sensor is actually working? Had anyone in the rear end that could have chipped or damaged the tone ring? Is it a hard code, meaning it comes back as soon as you turn on the truck, or do you have to drive a few miles before it resets?

What is the exact code? Open, shorted, inconsistent?

 

I physically inspected the wires

yes all the way to the pcm

put a new sensor on it

nobody was in the rear end

light comes back on after I brake and the brakes pulsate like the ABS activates

 

I hooked a voltmeter up to the sensor and spun the rear wheels. I couldnt get a reading on any setting. Could I have gotten a bad new sensor? Does anyone know what ohms I should be able to read? Can I test it when its out of the truck? Is there any way to test the Module to see if that is bad?

 

Bump!!

Anyone???
