If somone could lookup the code in the svc manual it will give proper insight. I'm at work right now (open manual, control + f, type code). The code may be generic, but the symptoms and causes, items to check vary. Consult the service manual it lays it out in plain english for the skyactiv g SPECIFICALLY
I checked all hose connections and clamp tightness on the air intake. All looked OK. I erased the error message (ECM light off) and will see if it comes on again which I expect it will. Since it is under warranty, I will not mess with it much, because of repercussions from the dealer experts ) Ed
check the maf plug first. check and if needed replace engine air filter. Spray maf cleaner on the maf. Run a fuel injector cleaner. see if the hose going into the intake has suction. no point in looking at the MAP sensor because it's gonna be covered in oil vapour anyways. anything else would mean replacing a part/ having a mechanic look at it.
