Well Heres the code meaning but being A Cummins that's as far as I can Go With Help On This Issue
•P0876 Transmission Fluid Pressure Sensor/Switch “D” Circuit Range/Performance
•P0489 Exhaust Gas Recirculation "A" Control Circuit Low
•P2080 Exhaust Gas Temp Sensor Circ Range/Perf Bank1 Sensor 1
•P2084 Exhaust Gas Temp Sensor Circ Range/Perf Bank1 Sensor 2

•P2453 Particulate Matter Trap Differential Pressure Sensor Signal Performance
•P0471 Exhaust Pressure Sensor Range/Performance
•P0037 HO2S Heater Control Circuit Low (Bank 1 Sensor 2)

 

it does have a new reman, trans 8 months ago from dodge , but those all seem easy fix . . but what is a little black box he keeps talking about on the passenger side frame rail ,truck runs great I have a 2005 dodge 2500 4 wheel drive now with 96000 miles on it I just don't like it ,its to high .lol I need a step ladder to get into my tool boxes lol

 

what is the heater control curcuit

 

Like I said In not A Cummins Mechanic So I Cant Help But If I was Going to guess id say heater control circuit is glow plugs circuit but I will leave that to Someone That Knows Cummins Well

 

im suppose to buy this truck tomorrow , its great shape runs great and everything things works . I know I will have to repair things .I,m just trying to figure if its worth it .the 1 code that comes back right away is the 037
