Good post. Thanks. Maybe after lunch and a little pasta and some Chianti we can take a look at updating our database. But first we eat! Mongia.
Abarth owners actually have an active system with sensors...the Classica and Lusso have a system without TPMS sensors. It actually looks at the rpms of each wheel to determine if one is running at a different rpm than expected to determine a low pressure. This is why it needs a set and reset function. The active system does not require this.
Not sure why Discount Tire is not on board...I bought a set of rims and tires from Tire Rack and they had the proper information. If you get in your owners manual it even describes the difference and how the Classica and Lusso work off the ABS wheel speed sensors.All I can say is that the first sensor was what was stated for (we later found out) non-Abarth models. They (both the dealer and Discount Tire) thought it would work at first and then found out it didn't. The dealer eventually went to non-oem as the reason. The sensor I now have works. I woud like to understand better why the system you talk about wouldn't be in the Fiat dealers books? They clearly stated that the Classica and Lusso used a sensor but that it was different. I wonder what the deal is?
do you have a parts list for this mod. I would love to be able to have the ability to change tires and wheels without the burden of purchasing new wheel sensors. also the tpms sensors tend to throw off the balance of the wheels requiring huge mass of wheel weights .Some people make a pressurized chamber out of plumbing bits large enough for sensors, throw them in, pressurize and strap it in the trunk never to be heard from again.
I also just got a set of tires and wheels from TireRack and they came with the 315mhz sensors. They work perfectly, I just tested one tire to make sure. Alarm sounded when I lowered pressure to 20 psi and reset when I brought pressure back up to 30 psi.Not sure why Discount Tire is not on board...I bought a set of rims and tires from Tire Rack and they had the proper information.
