My ABS light intermittently comes on. My ABS will kick in during slow stops on a dry road, and on icy/snowy roads it just skids without the ABS kicking in. It has done this once in while for the past month, but the past two days it has been continuous. Does this sound like a sensor issue, or something more costly?

 

The sensor is a good possibility, but on your generation vehicle, it's a question of which one?

Suggest that it would be a benefit to get the codes pulled to see just what the computer doesn't like. Whatever it is happens to be serious enough for the ABS system to not work at all.

At any rate, I just don't like troubleshooting by random replacement of parts - too much exposure toward introducing yet a 2nd problem to the situation, increasing the degree of difficulty.

Not sure how things are worked with your generation truck. For mine, the ABS computer was a completely different beast than the PCM, so required a different means to pull the codes from the ABS computer than the typical OBD scanner.

 

My light came on too while going and coming home from a trip. Since I got off the highway it hasn't come back on

I have no clue why it came on

 

Same on this generation, different code puller needed. Guess I'll be taking it in to Ford. Crap, I only have 3 months left on my lease, I am hoping it is just a sensor and not something costly like the ABS "brain". . that would be my kind of luck.

That is how mine started, it did it once, then it was fine for a month, then it started happening weekly and now this other stuff is happening too.

 

My Dad's Windstar did this at about 75k and it needed a new tone ring on one of the hubs.

 

i just had the same problem at 64 000km
The resistance of this sensor should be 800 to 3500 ohms.
mine tested at 3750 ohms, i replaced for $100 and problem gone.

 

Was it your rear one? From my research on here that seems to be the most common one. If it warms up at all before my appointment at Ford I will have to crawl under there and see what the resistance is. If not I'll let Ford deal with it.

 

Isn't your '05 still under warranty? Also, if it's failing all the time, how about disconnecting one sensor at a time? See if the problem gets worse or better. Might help you isolate sensors, but it might also generate a constant abs light.

 

My warranty was over 1.5 years into owning it, mileage. . .Unplugging the sensor will cause a constant light. It's a balmy 0 C (32 F) today, so I won't be crawling under my truck to monkey with it anytime soon.

 

yes, it was the rear sensor.

 

Update:

I had it in today, turns out it was the rear diff ABS sensor. 317 bucks, steep, but still beats crawling under the truck in this -20 C (-4 F) crap we are dealing with right now.
