Well, after the excitement of a starting battery exploding at 0300 in the morning, we had another adventure. Freightliner Portland replaced both starting batteries and we were on our way. About 5 hours into the next leg of the trip, a check engine light came on, and would not go off. I had a check engine light come on intermittenly during the last 4 months. I would shut down and check everything, and all was always normal.
It happended on a Friday late afternoon on Labor Day weekend, so on the following Tuesday we stopped into a Freightliner dealer in northern Oregon. A check with a diagnostic engine reader provided an active fault. The diagnosis was "Recirculated Exhaust Gas Temperature Sensor Circut- Voltage Above Normal, or Shorted to High Source".
The determination was that the sensor itself was bad and needed replaced. If the fault had occurred, the code reader would have recorded the incident, and the reader would have cleared the fault.
I did get stuck at the dealership while the replacement sensor came from Portland Freightliner
After it arrived, 15 minutes the sensor was installed, the engine cover put back on and we were down the road again. Hopefully our string of luck has changed, and we are enjoying life again. While the incidents were disapointing, I figured they are all in the RV experiance. Since we plan on fulltiming in 2 years, I figure we may as well get practice handling the unexpected. We managed to entertain ourselves while we waited, and even acomplished some chores (laundry).
All in all, life is good, and we are looking forward to hitting the road full time.
