Wheel speed sensor question?
Wheel speed sensor question?
Need some help. The slip indicator has been coming on more frequently the last month or so. Yesterday it came on driving down a straight road at a constant speed. It use to stay on for a minute or so, now it doesn't go off until I slow down to 10 mph or so.
How to I remove the wheel speed senors so I can clean them? Where are they located?

1 - At each wheel.
2 - 10 mm deep well socket to remove the single bolt that holds them down.
3 - Twist and pull to remove.
4 - Wheel has to come off. Don't get under the car without a jackstand.
Are your tires all the same size? I wonder if having different tire heights is confusing the ABS System (which is part of traction control).

225/35/19 245/35/19 combo
225/35/20 245/35/20 combo
235/35/19 255/35/19 (current setup)
I've had the current setup for about 11 months. Traction control issues just started in the last 2 months. It's becoming more frequent so it seems something is wearjng out. I'm hoping it's dirty sensors versus the tone ring on the axle. Were the sensors hard to pull out? I remember reading that they may break during removal.

I've broken them on a BMW taking them out but, on the 3 lexi I have access to, they just popped right out. I'm in the mid-Atlantic and rust isn't really a problem around here. I imagine the farther north you go, the worse the rust gets.
If you're really rusty, you might break them. They're not cheap to replace either. The tone ring is just a chunk of metal. I think it's unlikely you broke them. On the other hand you might want to check your wheel bearings and make sure they're solid. Bad wheel bearings can let the wheels wooble.
Might want to pull codes too.
That's the weird thing. I put my scanner on and found no codes. I don't get vsc or check engine lights when it malfunctions. I just get the slip indicator by itself, while driving calmly. I can for sure trigger the system if i accelerate quickly in a straight line or accelerate normally around a tighter corner. It isn't slipping though because it has come on while driving 40mph down a straight road. Wondering if the yaw sensor needs calibrating.
Anyone know how to do that?

TIS website gives you access to all the shop manuals for $15 for 3 days of access. That's what I do when I need technical information.

Sounds to me like the system doesn't think anything is wrong so no codes. There's nothing the system recognizes as wrong I mean, even though you can see it's not working properly.
