I need some insight as to what’s up with my tire pressure monitoring sensors. I recently had the sensors replaced because of some random XXX readings on right rear, then all sensors. Now we are in the middle of a mini road trip and both rear sensors went to xxx and eventually returned to a normal reading while driving. Someone mentioned to check the RCDLR module, but not sure how. I did do some research on replacing it but is seems to be a pain and reprogramming is required $$$. Plus the fobs have never been an issue. I going to buy the tpms reprogramming tool and try that as a solution. Anyone else experience something similar or have any helpful advice? Thanks in advance.
