Good Morning, we were towing with Dad's 2011 3500 Duramax this weekend home from a tractor pull. Keep in mind the truck only has about 13,000 miles on it. As we were going along the check engine light came on. We pulled off at a service station that had an OBD II scanner and the gentlemen said it was:
Code P2202 = NOx Sensor Circ Low Input Bank 1
Code P2203 = NOx Sensor Circ High Input Bank 1
At the same time we asked each other when was the last time that we added the DEF Fluid. We know we added it twice so far but went ahead and put some more in. The tuck took 5 GALLON, and the truck only has a 5 Gallon tank. The manual says the truck is supposed to give you a warning 1000 miles out, 500 miles, out, 300, 150, 50 and then limp the truck when you run out. None of this ever happened.
Do any of you guys have any input on this situation. We made an appointment for the truck. Can it be used to tow in the meantime? Thanks
