O2 Sensors in 8.1 litre W22 Workhorse
Having O2 sensor issues with my 2007 Fleetwood Southwind. Motorhome is built on the Workhorse W22 chassis powered by their 8.1 liter gas engine. Bought the motorhome new and currently has just under 50,000 miles. Only modification was the installation of the complete Banks Power System at the time of purchase. I am going through O2 sensors at what I feel is an abnormal rate.
At 32,000 miles the check engine light came on resulting in having one sensor replaced. Unfortunately the work order did not state the OBD code nor which sensor was replaced. Then at 38,000 miles check engine light came on resulting in code P0131 and the Bank 1 Sensor 1 O2 sensor being replaced. At 44,000 miles check engine light resulted in code P0151 and O2 sensors Bank 2 Sensor 1 & Bank 1 Sensor 1 being replaced. Now at just under 50,000 miles the check engine light is back and showing code P0131 and O2 sensor Bank 1 Sensor 1 as the cause.
Losing five O2 sensors in under 50,000 miles cannot be considered normal. To add to the problem these O2 sensors aren't cheap.
Anybody else been down this road? Any thoughts?
And one last thing. I'm willing to replace the O2 sensor myself, but in researching replacement O2 sensors I have found an interesting price difference dependent on how you word the search. Keeping the search simple such as 8.1 liter or GM 8.1 liter O2 sensor results in considerable cost savings compared to a search in which Workhorse and/or W22 is added to the search information. Does the Workhorse W22 8.1 engine really require a different or special sensor than a generic GM 8.1 engine?
Lots of questions here but this has become frustrating to say the least.
