If receiver reads 2 of them...should it not read all of them??? Originally, the scanner diagnosed which one of mine was no longer sending a signal.

Unless there are newer alternative parts, (?) "genuine" equipment & procedure (not difficult) is required, (not available @ most tire shops?). This is what I recall from doing mine a few years ago. Much has been written here on this. Try search: Resetting Tire Pressure Monitor? (New to me info about new EZ Schrader valves which can be cloned to the internal code of the original valve, thereby eliminating the need to reset the car's receiver? Anyone have success w/this?)
