My 2012 Honda Civic EX Sedan Tire Pressure Monitoring System (TPMS) light kept flashing even though all the tires had 32 psi. The shop tech said the batteries inside the transmitter's last about 8 to 10 years. Both of the rear sensors were dead and they needed to be replaced. Unfortunately, dealership prices were $XXX.XX for each sensor plus installation fees. Well that wasn't happening. So I went on line and I was very pleased to find these. Now I was a little skeptical not knowing it they would be pre-programmed. Once they showed up I took them to the shop and the technician used his scanning tool to check them out. Fortunately, they had all ready been programmed! The shop installed all four of them in less than an hour and I drove away! It's great not having to see that yellow/orange TPMS light on anymore! Don't waste your time paying high prices on dealership parts. I would highly recommend these to anyone!
