Check Engine Light
So, I left NC for a trip to Miami and back to see some relatives and check out our land in Georgia..... I got as far as Daytona Beach and a check engine light came on. All gauges were fine, truck continued to run good.... Went to Daytona Nissan and waited 2 hours for them to diagnose the issue. The diesel tech said there were "past codes" that were in the system that caused the check engine light to come on. Everything checked out as OK. He went through the procedure to remove the old codes and sent me on my way. Just about 145 miles later...the check engine light came back on. Again, engine was running fine, instruments were all in the normal range.
This time, I kept on driving all the way to Miami and back to NC.
This morning I dropped the truck off at my local dealership and they gave me a loaner to get to work. Hopefully, they can find out what is causing the CEL and shut it off. At least on this trip it wasn't a DEF system failure like the last time. I still love my truck, but I hate these little annoyances.
Since I had such a long ride and had some open road, I experimented with some driving speed and mpg. I had my fully loaded, slide in truck camper on, and at 73 mph, I was getting 14.5 mpg. At 63 I got 16.7 mpg.
