Had new tires installed. Ever since " service tire system" message has been on. on 2004 Chrysler Pacifica

Before the new tire install I got periodic messages of low tire pressure one tire at a time as needed. Mostly with lower temp changes. Always remedied with proper tire inflation. I should add that " service tire system" message remains even with proper inflation pressure.
Can this system be damaged during a tire change ? Where should I start to fix this problem. I'm pretty sure my Pacifica was built June 03.

Reply here for more info.... I'm tired of giving answers and getting NO response!!!... (IF you still need an answer that is...)
I still need the answer.
Sorry, folks usually do not reply.... Check the spare tire also! If problem persist, have a scan test performed to check data on the TPMS.
I just happened to check pressure of spare. Was OK. I'm taking your advice and scheduling a scan test. Thanks
One of the sensors most likely is the problem... Repair shop OR tire store/shop should be able to fix it right up!
Thanks for the follow up.
Sounds like your tire sensors are disconnected, or bad. Most places try to replace all these sensors when they mount new tires; but you don't have to.
