Calibrating tpms sensors
 

Long story short the tire dealer replaced a couple and they can't figure out how to calibrate. The dash keeps giving a tpms warning. Can we calibrate ourselves so I don't have to drive to the tire dealer for a third time because they had no one there smart enough to calibrate? Is this normally a tricky operation??

If we weren't going on a road trip soon, this wouldn't have turned into such a crisis and I may have had time to work through tis and an egr/throttle body issue which cost another $300. $770 for tires and 2 new sensors ugh.

Thanks in advance. Sorry so brief. Just want to get this out for a quicker response.
