TPMS does not register pressure
I recently bought a Doran 360 RV unit, I have this unit ready to go with the exceptuion of my right rear inside tire. This tire has a extension, when I put on the sensor I do NOT hear any air coming out so it does not register. However I can manuall read the tire pressure as well as fill the tire when needed. I have called Doran they had mention that I could back out the air valve a bit to see if this helps. NG, I am trying to find a 7 1/4 air stem ( the inner part of the extension to trhy that). Has anyone come accross this issue I haave a Fleetwood Southwind.
It doesnt appear to be the sensor and if I just push in on the needle no air comes out as well
