Has anyone experienced a problem with the Engine Coolant Sensor causing the "Check Engine" light to come on? The light came on while driving my 2012 F-150 about 15,000 miles ago. I stopped at an AutoZone and they read the computer code as being a problem with the Engine Coolant Sensor. Before I could get it into the dealer to get it checked out, the light went out and had no more trouble with it. Yesterday, the "Check Engine" light came on again and a computer code reader is again saying it is a problem with the Engine Coolant sensor. I checked the coolant level and it is fine. Also, both times the engine temperature gauge was right at where it always is when the engine is warmed up. Anyone had this problem or can offer info on whether there has been a service bulletin from Ford about problems with the Engine Coolant Sensor in the 2012 Ecoboost engines?
