Carbonedge, did this fix your problem? I have already replaced the OSS once for the P0970 error (ODO error) and it stopped for a few weeks. It has continued to happen intermittently. I carry a code scanner with me in the car and pull over to reset the system whenever it happens. Wondering if we should go ahead and have the TSS replaced as well.

I'm having the same issue with the OSS error. I keep the code scanner in the car and have to pull over and reset it. We've replaced the sensor once already (about two months ago). This is happening almost daily. My Edge is an 08 with 83,000 miles. I love the car otherwise. I will have to check out the theory of the cooling fan. Any other ideas to track down this gremlin would be most appreciated.
