After all the trouble shooting and process of elimination and investigation for a second go round in less than one year between full injector replacements, Honda America refused to concede that there might be an engineering/design problem going on. The Honda dealer addressed every one of their what ifs and they ruled out every other possible factor and basically it all came down to the cold hard fact that the Earth Dreams engine in my 2015 Fit has a serious defect. This engine does not have a PCV valve, it is just a tube. Pair that with the fact that there is no waste gate to trap the excess vapor and prevent it from coking up the valves, which is what it needs. Honda America would not hear it from me, or the dealership.... The Honda Engineer had one solution, put another set of injectors in it, and this time they charged me 30% of the cost and basically told me that the next issue is all mine to pay.... The Honda dealer was speechless. They knew, as well as I knew, this was just Honda kicking the can down the road. Honda America had no interest in getting to the cause and figuring out how to remedy the defect. All they wanted to do was treat the symptom again, for the third time. So I got screwed. I drive about 52K per year. The maintenance on that Fit was meticulous and documented. So, I had to fix it so it would run. Then I had to dump the car and take a loss on the trade in and get into something else that did not have the same design and history of DI carbon issues. So, now I hear that the Civic DI engines are coking up just like mine and the new recommendations from Honda America is a valve job every 30,000 miles, like that is normal. I have never had to have a valve job done on any vehicle I have ever owned and many were driven over 250K miles, with valves in good shape. So all the fuel savings go right into the cost of having to do a valve job every 30,000 miles which is preposterous.

Everyone else who bought 2015 and 2016 Earth Dreams engines are now experiencing what I dealt with back in September of 2015 with my 2015 Fit. They still do not have a remedy. Instead Honda is pushing it off on their customers to pony up the money for a valve job every 30,000 miles. This is not fixed by adding Techroline to the tank every 5000 miles. If you research how this DI engine handles the fuel, or mis-handles fuel; where fuel touches and where fuel never reaches, you will understand why it makes no difference regarding the carbon build up on the valves. Do not be fooled.

A set of fuel injectors to fix the code is nothing like doing a valve job.
