I've googled and seen this same issue with others, but no real solution.
The problem is the same I've seen where most commonly, the left rear tire loses signal and "Service TPMS" comes up on the EVIC along with that tire pressure going to dashes. I've had this on and off for almost two years. It's random and sometimes I can go for a couple weeks without it happening and then it might start doing it every day for a couple days. It always clears itself by the next day.
A couple times it's been both rear wheels that go dashes, but 99% of the time it's just the left rear like I've found on forums in google searches.
Others have obviously suggested replacing the TPMS sensor, but that's been done twice.
The other common suggestion is to replace the radio module on the frame behind the left front wheel and that's been done as well without fixing the problem. That was expensive to!
I saw a couple references that thought the left rear wheel was the only one without a receiver sensor, but I can't even verify that any of the wheels even have any sensors at all except for what is in the tire itself.
I was hoping to find a diagram to see how the system even knows which tire is which since the RF unit is on the left front frame.
Any help would be appreciated!
