I thought you had to remove the wheels to do this. What are you replacing again? Speed sensors right?

Yes that's right. I did remove the front wheels and fender liners to access the wheel sensor.

You replaced them without being 100% sure if it were actually the fronts. Also, you probably was supposed to have the system reset. Iíll just wait for an expert to chime in. I just knew how to bypass the issue temporarily and what was causing it.

Is it the rears triggering it?

BUT, don't forget to look through the hole where the WSS fits - spin the disc brake as you look - you should be able to see pretty quickly what the WSS is seeing and whether or not there is gunk in there causing/adding to the problem.

I'm still surprised at not seeing any codes.


I hate to sound like a broken record, but it seems as if suggestions are falling on deaf ears. Did you verify there is no gunk/debris? Did you find the resistance specs for the WSS's to verify good/bad? I am certainly no expert but in my novice mind, it seems like these two things would be good steps?

No debris. Don't laugh but I used a pick and a shop vac I'm the hole. I did find a leaking axle boot on the driver s Sorry, couldn't get a good camera shot of the hole in the spindle after cleaning.

However I don't have the resistance specs for each sensor

Did you spin the disc brake and look through the hole at the reluctor wheel to make sure the reluctor wheel's spacing/holes were all clear? Or just the hole that the WSS sits in?

Ohm the new WSS. Do both. Assuming they are good, that is the resitance you'd be looking at for all of them. I did only a limited Google, and I'm not sure how accurate this is, but I was seeing mention of about 13 Ohms. I'm curious to see what your new ones are. Check the old ones - see how they compare. Check the rears. Remove the plug at the wheel well and check there, as a start.

The reset procedure is to turn the wheel all the way to the right, all the way to the left, and back to the right. Should clear in the first few feet of driving.

Not doing it anymore after going into Dyno mode and going back. Weird. Works like new!

Does Dyno mode do some sort of reset on the ABS and ESP?
