I drove the car a short distance this afternoon, not sure if it was enough for a cycle but the check engine light did not come back on. I also should mention that when I was looking at the temp sensor, it was dusty and I took the opportunity to clean it.

I might be good to go at this point but I will drive it a few times and see if throws any more codes.

Thanks again for the tips.
