Just got a 2011 Ram 2500 CC LB from OK from auction (sight unseen). It was a 1 owner fleet/company truck with 210K. I got the truck transported here and upon delivery found out trans only works in 4th gear when in D. Put my scanner on it and came up with 31 codes!!!
I also noticed that many times when I turn the key to start it doesn’t turn over or do anything. I have to wait and keep trying. Also when I put my scanner on real time information reading I got a few error codes LINK ERROR check connections try again and blank screen for real time data. After trying a few times I was able to read the data stream while engine was idling.
Confirmed Codes taken at first:
P2509 ECM/PCM POWER INPUT SIGNAL INTERMITTENT
U010C LOST COMMUNICATION WITH TURBOCHARGER CONTROL MODULE A
P2262 TURBO CHARGER BOOST PRESSURE NOT DETECTED
P0471 EXHAUST PRESSURE SENSOR A CIRCUIT RANGE/PERFORMANCE
P0750 SHIFT SOLENOID A MALFUNCTION
P0846 TRANSMISSION FLUID PRESSURE SENSOR/SWITCH B CIRCUIT RANGE/PERFORMANCE
P0871 TRANSMISSION FLUID PRESSURE SENSOR/SWITCH C CIRCUIT RANGE/PERFORMANCE
P0876 TRANSMISSION FLUID PRESSURE SENSOR/SWITCH D CIRCUIT RANGE/PERFORMANCE
P0988 TRANSMISSION FLUID PRESSURE SENSOR/SWITCH E CIRCUIT RANGE/PERFORMANCE
P04DB CRANKCASE VENTILIATION SYSTEM DISCONNECTED
P014C 02 SENSOR SLOW RESPONSE RICH TO LEAN (BANK 1 SENSOR)
P0111 INTAKE AIR TEMPERATURE SENSOR 1 CIRCUIT RANGE/PERFORMANCE
P2BAC OXIDES OF NITROGEN EXCEEDANCE DEACTIVATION OF EXHAUST GAS RECIRCULATION
The rest are repeat of above codes pending.
I did try to clear codes but 9 came back: P0750 (confirmed), P2BAC (permenant), P0111 (permenant), P014C (permenant), P04DB (perm), P0988 (perm), P0846 (perm), P0871 (perm), P0876 (perm), P0750 (perm).
I decided to try to drive it before I towed it into shop so I put it in D and let the truck roll in idle until I built up some speed then pushed the accelerator and it almost drove like it was normal on city streets around the house. I didn’t go over 40 mph so 4th gear wasn’t bad. At the stop signs I let it slow roll instead of stop so it accelerated when I needed to.
I want to get it repaired but don’t want to take it in without any background info on the issues so will try to get an idea of what is wrong beforehand. Do you think this is failure of hard parts (trans, sensors, solenoids) or more of software, ECM/PCM or wiring/harness issues or a little of both. I was told trans stuck in 4th is limp home mode what can cause that condition?
Where should I start with this?
