Traction control and ABS sensor

Nope there is no wear. I am not sure about the Is300 setup but a lot of cars use a hall sensor and this is a non contact sensor so nothing wears out. Basically it just compares the wheel speeds from the front to the rear, if they vary past a certain % then the power is cut to the rear wheels, thus maintaining traction.

You've got nothing to worry about.

thats good to know

hey conrad turbo, you should be a tech mod for this site

I don't believe that's the way our traction system works.

I think it just sensed wheel spin and cuts engine power.

How does it sense wheel spin

From a proximity sensor that compares the wheel speed to a known value.

By the same token the ABS is activated when a sensor detects a wheel NOT turning.

a proximity sensor?

yes

hehe. proximity of what to what

The sensor to a rotor so's it can count the revolutions.

the speed sensor.

what conrad_turbo was saying a few posts up

You can call it that, but it's generic name is proximity sensor.

However I don't think Conrad was correct about it comparing speed with the front wheels.

Thanks for all the input.

The speed sensor doesn't really wear very fast. My guess is you'll have to replace one or so around 90k.

If you've had any modifications done to your car...if you've replaced rotors or brakes...especialy if you've done suspsension work, the speed sensor could have been damaged. (but in this case you'd get a CEL)

There is nothing wrong with your car. Just stop sliding around or turn trac off. it's more fun that way anyway.
