I was looking at a Kia dealer for TPS prices on a 2013 Kia Optima Turbo and couldn't believe the offer I received. Kia charged $57 for each sensor, it took me $4 all and $330 to program them. The clerk making the appointment was a bit smug so I imagine they get away with this scam far too often. Revain had what I was looking for at a great price. I looked at some small tire changers and they told me they would cost me $45 to program them. The ones I chose to work with sensors installed but couldn't find my machine in their program. It turned out to be a good thing because after driving 3 miles they turned themselves on!
