2006 F250 codes
i have a 2006 F250 with a 120 thousand miles 2 weeks ago. I blew a high pressure oil pump so I had that replace along with a new oil cooler and a heavy duty egr cooler he also upgraded the fitting. I pull a goose neck trailer with it, Yesterday the check engine light came on. I checked the codes and this what came up code p0470, p0232 and p1379. It also threw out the code u1900 I disconnected the battery to reset and it has not come back on so far. what is this telling me? also I put two new batteries in. thanks

P0470 Exhaust Pressure Sensor "A" Circuit
P0232 Fuel Pump Secondary Circuit High
P1379 Fuel Injector Control Module System Voltage High
U1900 CAN Communication Bus Fault - Receive Error
Looks to be electrical. Check all the battery connections, positive and negative. Clean and reconnect. Check for chafing around FICM harness. (as best you can, tight area in there.
Any way to check readings? Like a Scangauge II or something?

Well, these codes seem unrelated to me, except they are all "voltage high" errors.
P0470- EBP "A" circuit high
P0232- Fuel pump secondary circuit high
P1379- FICM volts high
U1900- unspecified but likely a likely data error of some type.
Sounds like something shorted for a second. I would look over all the wiring that was disturbed during the recent repairs, and check the alternator for a/c output on the main lead. Battery power (v) is limited to the current state of charge for the batteries and shouldn't be a problem so I'm thinking vRef (normally 5v) is shorting to battery power somewhere or charging system output was too high.
Just thinking out loud here, maybe some of the more experienced guys will be along with a better answer.
