So does that mean the receiver on the car is only able to communicate with a single frequency, or do you mean I can't mix and match between a 2017 sensor and 2016 sensor. The reason why I ask is because I bought a set of OEM Volt wheels from someone else that offered to toss in three 2016 OEM sensors as well for free (have no idea what happened to the 4th). I haven't actually looked at the stuff yet but I'm getting ready to buy some winter tires to get mounted and need to either fill in that gap by getting a 4th 2016 sensor, or buying a full new set of 2017 sensors...
I figure I'll also buy the tool that allows me to re-learn the wheels to the car since I'll have two full sets of wheels/tires and don't feel like heading down to the tire shop twice a year.
