I had the same problem. No engine light, or codes. The little wrench would come up, then it would go to limp mode. Worked on it for a while before figuring out it was the MECS pump. Replaced and refilled coolant, no more problems.
Hi All!
Bought a 2010 Fusion Hybrid a while ago. I have had a few problems with it (not many). Wanting to learn all I can about it.
I can also help out others with what I have learned about this amazing car. 8-)
