ABS false activating every stop

mudgripranger · #1 02-26-2015, 08:27 PM

So i bought a 05 2wd 2.3L ranger and the tire sizes were different. the back ones were bigger than the front ones. I asked a few people some people said tires, some said sensors, etc. So I went with brand new speed sensors and that didnt fix it so i said screw it and bought four new kenda klevers. My abs used to false activate every stop no matter how smooth i made it. now it still false activates but at random times my abs light will come on along with a brake light and abs will completely shut off after i brake a few times. I have know clue whatsoever about how to approach this

You need to read the ABS code to find out which sensor is not working.The ABS will shut off if a fault is read and resets when you turn off the key. Bad sensor ring,low voltage on a sensor read the code to narrow it down.

I think you just said what your problem is with "my abs light will come on along with a brake light".

Brake light either comes on when parking brake is on OR if you have low fluid level. (information is from your manual page 11)

Check your fluid level and bleed your brakes. Check for leaks, especially at the calipers, wheel cylinders, and master cylinder.

I got brand new calipers, my fluid level is good i bleed them 2 months ago when i put the new calipers on

So bleed before this happened? or started happening before being bleed?

Also which sensors did you replace how many and where?

It has been doing this since i got it but when i put new tires on it the abs and brake light come on at a random time and abs shuts off. there are only two sensors and i replaced them

Actually there are three sensors, that is why I asked. There is a third on the rear differential on the top.

May want to remove it and see if there is crud on it, and also check the hole where it goes.
