Did not delete fault, next day morning switched to map 0 turned off ignition and then restarted and engine light went out. Connected and fault still in in as P0400. Have an appointment tomorrow for the fault since I still have warranty and pulled the JB4 this evening. Is this going to be an issue with the truck or the JB4? Iím rolling up on 96,000kms and installed JB4 at 93,000kms. Let me know. Can run whatever tests you want me to with JB4 installed once I get the truck back from Ford tomorrow. Thanks!
Did anything else come in the description besides the code?
