I am wondering if anybody here is familiar with the TPMS on a Volvo XC-90. My wife's Volvo XC-90 3.2 AWD has been giving intermittent message of "Tire Pressure Syst. Service Required". I'd assume that there is something wrong with its TPMS. How does the TPMS on this kind of Volvo work and is it possible to figure out specifically which sensor broke and needs to be replaced? Thanks all.
