A 2016 TPMS receiver will only work with 315 mHz 2016 sensors, and a 2017 receiver will only work with 433 mHz sensors.
The part number (and frequency) is printed on the sensor (have a magnifying glass handy...the print is small). The correct part number for 2016 Volts is 13598772 (315mHz). The correct part number for 2017 Volts is 13598773 (433mHz). I got a set for my 2017 off of Amazon. Their photo, when expanded, showed that the sensors were made in the U.K. When mine came, they were made in the U.S. These are actual GM parts, not Chinese ripoffs. I mounted my winter setup yesterday. The sensor learning procedure went exactly as described in the Volt owner's manual and took less than two minutes, even though I was being careful.
