Hey guys,
Today I was 4 hours into a 5 hour pull with my 30' travel trailer(7000 lbs), I was going up a long (maybe 3 mile) steep uphill, hitting it pretty hard, keeping it steady at about 70 mph. Rpms were about 3500ish and Drogo (09 sierra 2500 LMM) was working his ass off. Check engine light came on, I backed off, obd2 reader in my entertainment system wasn't giving me my code, I checked tranny temp, running 205°...a little high ,but i wasn't too surprised with what I had been putting it through and had been going for 4 hours straight. It drove fine the last hour home, I was more gentle on that rest of the hills. My system finally gave me my code... P0234... *P0234is a generic OBD-II*code*that is triggered when the Engine Control Module (ECM) detects that the intake boost pressure sensor input signals intake pressure above the maximum specified pressure by 4 psi for more than 5 seconds.*
Further reading it sounds like it can be pretty brutal if not fixed. My check engine light is still on (will it go away without clearing it?) but it seems like it was just situational from the conditions during that part of the pull... Or is this something that has to be repaired now? I have a 200 mile (400 round trip) trip on Monday I need to do, not towing or carrying anything, and I can't get it into the shop before then. What are your thoughts? Is this code usually a big deal?
