No the coolant sensor hasn’t been fixed would this cause check engine and overheating lights to come on. My car also doesn’t rev
The recall adds a coolant level sensor to alert you if the coolant level was low. There wasn't a coolant sensor installed. Ford's theory was/is that low coolant caused the overheating issues leading to cracked heads.
I won't say all, but many Fiesta STs, have cooling issues. I live in GA and mine would overheat in high ambient temps and would overheat on the track even at 50 degrees F. The earlier build cars had head gasket issues.
- Did you call Ford today and verify it has an open Recall? Schedule an appointment and take it in.
- What do you mean "my car also doesn't rev"?
- Is it throwing the overheating symbol at start up? Does it show the check engine light immediately?
