The Tire Pressure Monitoring System (TPMS) light on my 2012 Honda Civic EX Sedan kept flashing even though all tires were inflated to 32psi. Customs service. The seller said the batteries in the transmitter last 8-10 years. Both rear sensors were dead and needed to be replaced. Unfortunately, dealer prices were $XXX.XX per sensor plus installation fees. Well it didn't. So I went to the snake and was very happy to find it. Now I was a bit skeptical as I didn't know they would be pre-programmed. As soon as they turned up, I brought them to the store and the tech used his scanner to check them out. Luckily they were all already programmed! Master installed all four in less than an hour and I was gone! Great not to have to see that yellow/orange TPMS light anymore! Don't waste your time buying overpriced parts from dealers. I would highly recommend them to anyone!
