Tyre Pressure Sensor

[Jamin Berry]

Are they wheel specific?

I mean if i bought some aftermarket wheels would they not work?

thanks

Good Point!

I might be corrected on this but I believe there is no actual sensor in the wheels the ABS and ESP are used to keep an eye on the handling if it alters significantly in a short amount of time it gives a warning.

I assume if you have new wheels when you have them correctly aligned and the right pressure you then just push the reset button and it learns the handling characteristics again with the new wheels.

I can't actually remember if the reset button is on a button by the handbrake or if you hold the handbrake button down until you hear a beep, someone else will probably be able to tell you or check the manual

Hope that helps

You're right there!

Yep. I had a good old shufty at my wheels when the tyres were changed and there is definatly no sensor on the wheel.

I believe that the hub can count the number of rotations the wheel makes and then compares that to the distance travelled. If the tyre deflates the wheel diameter decreases, and will travel less distance per revolution - and the warning light comes on.

Well something like that but along those lines and definately no sensor in the wheel or tyre itself.

No sensor at the wheels and works as said by Trident.

Reset button is on centre console near to handbrake, TCS button etc.

I had to reset mines a few months ago when I got a new tyre fitted. After about 5 miles of driving the 'sensor' must have picked up a change in tyre - even though it was to the correct pressure.

Sorted!
