Got a 2012 Maxxforce DT9 throwing a 164 13 code for ICP adaptation in-range fault. It’s been doing this for quite a while, high pressure oil rail has been resealed and a new ICP sensor installed with no change in how/when the code comes and goes. Starts fine cold or hot, no drive ability concerns. Hoping HeavyD or one of the other Navistar experts can chime in.
Thanks in advance.
