FLynes Posted May 26, 2022 Share Posted May 26, 2022 (edited) 8.1L, on our way to Las Vegas and about 3/4 of the way to our first stop in Wells, NV, the rig started feeling gutless going uphill. I kept the cruise control on, which seemed to mitigate the issue. Yesterday morning we gassed up at Flying J and started off. Not even five miles out of town the check engine light came on, so we turned around and went back to Wells and spent the next several hours on the phone with Good Sam. I managed to get a mobile repair guy to read the codes, P0131 and P0151, low-voltage circuit O2 sensors Bank 1 & 2. I spoke to Jon Brazel, from Ultra RV, who is the nicest and most helpful person. According to him, the odds of both O2 sensors going bad is incredibly remote and points to the MAF sensor being bad. It was one of the things I cleaned, when I serviced it before the trip, so I ordered a new one and two new O2 sensors, to be safe. Barbra, the parts specialist at Ultra RV made sure they went out overnight to the dealership in Elko, where it’s being towed. DW is incredibly calm about all of this, calling it an adventure, which is what makes her so great. Edited May 26, 2022 by FLynes 1 Link to comment Share on other sites More sharing options...
Martinvz Posted May 26, 2022 Share Posted May 26, 2022 Hi Frederic, Very sorry to hear of your misfortune. I have worked with Jon at Brazels in the past and found them very helpful for the W24 chassis. Hope you get the repairs done and are able to continue soon. We have a ‘06 LaPalma with a W24 similar to your coach and are also on the road. Martin 1 Link to comment Share on other sites More sharing options...
Trinidaddave Posted May 26, 2022 Share Posted May 26, 2022 I can’t offer much help with your coach issues, but since you’re stuck in Elko the family style Basque food at the Star Hotel shouldn’t be missed. safe travels 1 Link to comment Share on other sites More sharing options...
vito.a Posted May 26, 2022 Share Posted May 26, 2022 (edited) The rear O2 sensor is only there to determine catalytic converter health. No big deal if it fails it just lights the service engine light. The front O2 sensor sensor schedules fuel when in closed loop mode. If it fails it just goes open loop and again lights the light. The MAF tells the ECU how much air is entering the engine so it can schedule the proper amount of fuel. So, I agree this is the most likely suspect. You will need a special O2 sensor socket to change them. It has a slot up the side for the wires. Next time, these parts should be available at any Chevy/GM parts place. Best of luck!

Riverton Chevrolet in Elko doesn’t have the parts and they do NOT work on medium or heavy chevy trucks. It’s being towed to Gallagher Ford, which does work on RVs. I’m having the heated O2 sensors changed merely as a precaution, as the rig sat for about three years without use. Link to comment Share on other sites More sharing options...

We’re in Elko now, sitting in a nice park with homeless people sleeping on benches enjoying some lunch. The parts from Brazel’s arrived right before we got to the dealership, so we should be back on the road this afternoon. Link to comment Share on other sites More sharing options...
6Wheels Posted May 27, 2022 Share Posted May 27, 2022 It appears that you also are temporarily homeless! Glad to hear you have it resolved, it could have been a lot worse. 1 Link to comment Share on other sites More sharing options...
