“Engine Coolant Over Temperature”
Hey all,
I’m a bit unfamiliar with car maintenance, so forgive me if you have to explain it to me like I’m 5.
I have a 2020EcoSport SES, I went to leave today when “Engine Coolant Over Temperature” and the “check engine” light both came on. Car was definitely not overheating since I had not driven it in almost a day.
I didn’t drive it today. Once those came on I kind of got paranoid. Had someone come over and run diagnostics and got these codes.
P1289 Cylinder Head Temperature Sensor Circuit High Input
P1299 Cylinder Head Temperature Protection Active
(This came on after the engine shut off. We ran the engine to see if it was getting too hot and it never went above 200F)
also, the temperature gauge never moved. Stayed to left when it typically stays in the middle. When the engine shut off, which I’m guessing was a safety feature, it did shoot up to the right and went quickly back to the left when the car was started again.
Bad sensors? Advice? Thanks in advance.
Sincerely,
A paranoidFord owner.

I had a similar issues in my car and if you take it to the dealership, the dealership will replace the sensors but it’s not a sensor issue. There is some kind of other defect and not to confirm your paranoia but mine ended up catching fire. I found someone on here with a similar experience with the same fiery outcomeHey all,

I meant to update this post.
The day after I made this post I had the car towed to the closest shop that had an opening. I told them what was going on and I get a call from them a couple of hours later and told me it wasn’t my sensors, but that rats/mice have chewed through most of my wires.
I live in a smaller sized city in an apartment and have been parking in the small back parking area, which is in an alley, and that alley is where all the trash cans and dumpsters are located for everyone on my block. Adding to that, the house beside us has an unkept backyard along with a storage shed that is also unkept. I had seen rats and mice a few times, but never near my vehicle.
So needless to say, I stopped parking in the back and once the wires were replaced, all the issues were resolved.

Circuit high means either the sensor is unplugged, or the wiring is damaged.
