How do I find out which part I need? Im finding 2 different part numbers for the sensors, and the main difference I am seeing is the frequency:

F2GZ-1A189-A which shows 315 MHz

F2GZ-1A189-B which is 433 MHz

Also, the A sensors seem to cost about double than the B sensors.

 

A 2015 truck TPMS system is under warranty ...have Ford fix it

 

I'm going to be adding a second set of wheels

 

I just purchased a set for my new 20" PVD Ford factory wheels. The part number is F2GZ1A189A. List is $43.53. I paid $34.99. They work perfect. Hope this helps.

 

Anybody else?

 

I checked my ETIS Summary sheet and it says the freq is 315 MHZ on my 2015 Platinum.

 

433mhz is for export vehicles only. As another member looked up, if you have access to your build sheet that will say.

 

These are the sensors you need. I have on my truck: F2GZ-1A189-A 315 Mhz
Ordered from TASCA with TPMS-19- TRANSMITTER - TPMS CALIBRATION

 

Strange FCC states that both are legal for use in the US. I use 433 MHz for RC Aircraft Control. I also hold a Ham Radio Lic.

Wonder why they would pick one over the other. I would think the power level is very low also out of these.
