My abs light is on, and just the regular brakes are working Abs is not.

Is it just the replacement of the sensor or do you think its more than that.

Any ideas or steps would be appreciated

Thanks

 

Hey guys,
Can anyone please give me a starting point on what to start checking first?

 

My ABS light was coming on. I went to Napa & purchased the abs sensor for about $20.00. Changed it out in 5 minutes. (Removed from the top of the rear differential.)

Thanks, i had a look today above the rear differential, but not sure i know what i am looking for. Does anyone have a pic of a rear ABS sensor just to give me an idea of what i am taking off? Since it is the first time i am replacing this.

thanks

Anyone happen to have a picture of what the rear ABS senspr looks like above the rear differential?

Also, any special tools needed for this removal?

Thanks guys

 

I have the same issue, id like to see these pics as well!

 

I don't have a pic of the sensor, but it's the only thing on the differential that plugs into the chasisis wiring harness. When I had the same problem, the wire harness was cut near the differential. I spliced in some new wire and covered the splices with a new piece of wire loom I bought from Murray's.

 

Hey man i have a thread started about the same thing

The sensor can not be missed it just about the rear diff where the d/s inserts into the diff.

It's probably pretty dirty there and it has a connector that should be un-clipped and then it's just 10mm bolt towards the back of the sensor.

I pulled mine and it read 1900 ohms so i think mine is bad.

Dealer wants $34 for it so i'll check napa instead.

Thanks guys, slight problem, the bolt was so seized on i tried very carefully to take it off and i rounded off the head of that bolt. Any ideas on how to remove this small bolt????
