Good morning all! I am on her for a friend. She has a 2016 Fusion with the 2.0t engine. As the title suggests, she is throwing 2 CEL's, the first being Turbocharger 'A' Underboost Condition, which I'm thinking is most likely caused by the other code, cylinder 4 misfiring. So far I replaced all 4 spark plugs, but still the same issue. My next thought is that possibly coil pack #4 is causing the issue? We are wanting to try swapping pack 4 with one of the other packs to see if the problem moves to that cylinder instead. Are the cylinders ordered so that cylinder 1 starts at the left, then number 4 would be all the way right? Other than trying the coil packs, if anyone could offer more insight into the issue, it would be greatly appreciated!
