A couple of weeks ago my 2000 Blazer. Rwd. Stareted engaging the antilocks on at slow.almost stopped.speed I checked the codedand came up dry on any reference to which sensor it is. I also read where there is a rear sensor. My blazer has a manual transm


Is there a way to tell quick sensor is acting up?
And are all the sensors the same from the. 4x4 as well as the 2x4?

 

Very common problem, and it does NOT set a DTC in memory. Here is the GM technical service bulletin, (TSB). It explains how to test and repair it: https://blazerforum.com/forum/tech-a...ment%5D-26941/

 

Had this problem last week I had to replace the front wheel abs sensor and it cured the problem. It's pretty dangerous to drive with abs kicking in like that. The new sensor came with different shims I ended up using no shims to get it to work correctly.
