Ok our 2012 chevy vans have been pretty much bulletproof except for this one thing. Every one of them has code p0202e come up every few months threatening to reduce speed. Its for the def injector cicuit bank one. I was going to take one to the dealer but they couldnt look at it for a week so I cleared the code and sent it off until it the dealer was ready. The code didnt come back so there was nothing to diagnose. Im sure the code will be back in a few months . IS this something to worry about or just a glitch in the software /hardware of the def system. I would think if there was an actual problem the light would come back on right away. Any ideas?
