Hi,

I have a converted (Camper,longer Body) 2001 RAM VAN 3500 5.9L

I recently got Check Engine Light that came on, checked the code and got P0138 O2 Circuit High Voltage (Bank 1, Sensor 2), if I understand this correctly this would be the rear Oxygen Sensor

From what I can see it seems to have 2 Catalytic converters, is this possible?
If it has two converters, which one is the Bank 1, Sensor 2?

Anybody Know where I can download a Service Manual?

Any help will be greatly appreciated

Thanks
