My truck has been sitting in the shop for over a month. Not sure if the DPF, the DEPS, or one of the connectors.
The CEL came on in February (P16F3). ECM was updated. Could be unrelated.
In March CEL on. P24B1, P0381, P113E, P140B. I took it into the shop on a Saturday and they found those codes. They don't staff diesel tech's on weekends so they reset the CEL and told me to come back on Monday.
By Monday CEL was back on. P24B1. I also started to see the regen message. This was the first time I ever saw the regen message and I had 14k on the truck. I only drive highway so I assumed I was flushing the stuff with my driving habits.
They told me the Diesel Exhaust Particulate Sensor (55590140) had to be replaced. They let me leave the shop with the truck because they had to order the part and said, "It was perfectly safe to drive". Within 30 miles my truck went into limp mode on a large highway. Going 45mph on a 70mph highway isn't "safe" IMHO.
Got the truck to a new dealer. They found cod P2463 - Diesel Particulate Filter. They replaced the DPF.
I got the truck and within 50 miles CEL came on.
Now it's back in the shop and I'm told the connector to the sensor has a bent pin (or connector). No ETA on that.
