TPMS question
I recently pulled off one front wheel at a time on mt 2013 Grand Sport. Did not switch them. Now the psi reading in the dash for the front is off. The rear is fine. What did I do? Set the wheels out of range? I assume the sensors need to be reset?

No the car doesn't need to be programmed to recognize the sensors again. Drive the car for a couple of miles and see what happens. Programming only allows the car to memorize the identity code for a particular sensor. That is why you start at the left front when programming the sensors. You get the one at the left front to broadcast its code and the car sees it and records the number and then continue through the other 3 tires. Again, programming has nothing to do with the pressure reading only with identifying the sensor that is broadcasting a signal.

Thanks Bill. I've put at least 200 miles on the car after I pulled the wheels off. I have a 10 lb differance between the two front tires according to the car gauge. My Moon tire pressure guage tells a different story. I guess that's what a warrantee is for....lol...
