TPS System

Dele Z. · 02-01-2012, 07:16 AM

I'm about to fit some Aftermarket alloys to my wheels and i just remembered Ive got Tyre Pressure Monitoring on my car

Does this mean i have to fuck around with a sensor in the old alloys?

related to abs system so don't have to do anything except set it

All the system does is compare the rotation of the wheels, if one tyre loses it's pressure its circumferance will reduce and thus rotate quicker. So, in no way linked to the wheels or tyres themselves.

I read that the US models had sensors, just checking if we did

No - thats a US law thing so they have to have 'proper' sensors.

Does the TPS system compare rotational speed to the correct RS or simply to that of the other wheels?

Relative to other wheels.

So if all 4 wheels get punctured together it wouldn't know the difference??
