Hey guys. As it is with Murphy (damn him), and my luck, I had a CEL pop up two days ago on my truck. Of course, just when I need it on a trip, and of course, one month after the extended warranty expired! Anwyay, I plugged in the ELM and connected to Forscan Lite, and it was a P21AB - Reductant Level Sensor B Circuit High. I cleared it, but it returned the next morning. I didn't drive it again until today, and it was still there. Being related to the DEF, I checked it, and it was "under 1/2 remaining". I figured I would stop and pick up some DEF and fill it, and see if it was just beyond the sensor. The dash also popped of a "800 miles remaining" message just before I got the DEF. It did take almost two full jugs. Afterward, the CEL did clear, and it seems to be fine. I checked with the dealer, and they advised against driving it. They said when it goes into regen, it will go into limp mode.
So after that sorta long sob story, what do you thing. Will it make a trip from Houston to San Antonio. I'm my pulling my 5th wheel, just me, the wife, a son, and a dog. And a back end full of presents for the other sons and grandkids. If it is something that will re-occur, I will try to replace it...I've done some sleuthing online. Dealer estimates from others with this code were around $800. Anyway, let me know. My trip is tomorrow.
