Hi Scotty,
2 years ago I replaced all TPMS sensors in my Tacoma with Denso ones which worked fine until last week when I got the TPMS light on with the 2 ODB errors: C2177 and C2125. My TPMS scanner cannot talk to the ECU. I have reset the ECU to no avail but it worked in the past. Please what's wrong?
Thank you.

Well if it talk to before and won't now odds are the module in the car has gone bad. Any good tester you can test individually each sensor by going to the wheel and checking them. You can do that to check the sensors, but if they're working then there's a problem with the module in the vehicle that accepts the signal
Yeah, all 4 wheel sensors are healthy. I guess either a have a wiring problem or a bad TPMS ECU.
