I think I scored a great deal! I meandered down to a salvage lot today and swapped my '07 ex tire/rim combo for an '07 sc tire/combo. Did it myself in just a few minutes....but i have the problem. The problem you all know i have. The problem i don't know how to fix without going to the local dealer. I would really appreciate any tips on how to fix the TPMS sensor. Help?

You need the TPMS sensors that were in your old wheels.

If the TPMS sensors are in the EX wheels, you can go to the dealer or a
tire shop and they can reprogram the new TPMSs to your E.

no diy method huh? bummer :|
