IIRC 2004 roadsters do not come with tire pressure sensors. I was wondering if its possible to activate the TPS on Z's that did not come with it originally. I just picked up a set of Track rims for my roadster which came with the sensors.

I'm not sure how the TPS works. Would this just require a ECU reflash to display this in the pressure on the info guage? Does it need sensor recievers? Sorry for the silly question, hope someone can tell me if this is possible or not. Thanks.

 

Here's how it works....

The sensors in the wheels transmit a signal picked up by an antenna mounted in the A-pillar. The Low Tire Pressure Warning Control Unit takes that signal and processes the info and controls the warning light and the TPS display in the triple-meter.

If your car didn't come from the factory with TPS, then it won't have the antenna, the control unit, etc. I doubt there is something you could set in the ECU to enable it once you've purchased wheels with sensors.
