That is correct no sensors in the wheels. From another post "I don't know why Honda went with this setup. I can speculate that the public does not want TPMS sensors in the tires due to the added cost when changing rims, and their is probably a cost savings due to the fact their is no hardware in this setup just software piggybacking on the traction control system, but the US auto industry is mandated by government to have some form of TMPS. At first I thought this was a neat new innovation for the reasons above, but as I read up on it I quickly found out that this is really old technology, in fact this was the very first TPMS of any kind and was quickly replaced due to its many flaws. The flaws that allow false readings are tire spin due to road conditions and change of wheel circumference due to snow or mud build up on tires. Honda Canada was lucky, their is no such government legislation so they just eliminated TPMS from the entire Civic lineup, it's the first manufacture to omit the TPMS in three years and will probably set a trend among others."
