Use AE to find which TPMS sensor is bad?
 

2004 EB w/4x4 v8, I routinely get a TPMS error msg on the message center and the warning light on the dash.

I've tried using AE before, but it seems you need to be driving for the sensors to be transmitting in order to identify which 1 is at fault?

Could it also be 1 tire is slightly under-inflated vs. the others?
