There is a chemical test to check for this.
A leaking head gasket is usually accompanied by the loss of coolant from the reservoir. Thermostats have to be hit with hot liquid. The gases that get into the cooling system can pool under the thermostat and cause it to not open. i have a 2014 ford escape with the 1. A large butterfly collection in the radiator will do that too.Īnother real good suspect is a leaking cylinder head gasket. I replace the engine coolant temperature sensor in the cylinder temperature sensor location for the 2013 Ford Fusion 1.6 L turbo ecoboost engine and my scanner is still pulling and its still stuck in limp mode how do I get it out of limp mode and whats causing it to stay in it. It also depends on scanner your mechanic checked it out with in regard to codes, this example explains. Your car is too new for this, but if running the heater on "hot" and the fan on a higher speed brings the engine temperature down, corroded cooling fins on the radiator are a good suspect. R.S.LOGAN said: Overheating is a cause of going into limp mode and could be caused by faulty CHT Coolant Head Temperature sensor but there are also so many other possible causes. That is not needed at higher speeds where natural air flow is sufficient. If speed is a contributing factor, and the overheating only occurs at low speeds, suspect the radiator fan is not turning on. First you have to determine what affects the overheating. That, of course, may be why I didn't get the same warning again at the end of my drive.)Īny suggestions on what may be causing this behavior? With no codes showing up to guide me, and with both the engine operation and engine coolant temperature appearing to be within perfectly normal ranges, I'm struggling to understand what might be going on.Īny suggestions you might have will be greatly appreciated.The sensor is telling you the engine temperature is too high. (The outside air temperature did drop probably 20 degrees, though, with me driving into a storm front. I again pulled over and waited 15 minutes, after which I drove the car home without the warning appearing again (another 90+ minutes), with the coolant temperature again staying in that same range. When I picked the car up on my way home, I drove about a little more than an hour, and received the same message (with coolant temperatures showing mid-80s C). I drove cautiously to the next town, where I rented a car to make the rest of the trip rather than risking another seven hours of driving with a warning I couldn't explain. When we left, the warning had disappeared, and again, the coolant temperature was showing in the same range. I pulled over again (this time at a convenience store) and we grabbed a bite to eat while waiting for the car to cool down again.
After about 20 more minutes of driving, I got the same audible alert and the same red box, with coolant temperatures showing right where they had for the past 30 minutes of driving. The car ran fine, and showed coolant temperature fluctuating between about 88 degrees C and 95 degrees C (190-203 degrees F). Outside temperature was in the mid-90s Fahrenheit, so those don't seem like particularly high temperatures.

However, I left the code reader on and connected to my phone via bluetooth so I could monitor the engine coolant temperature as I drove. At this point I put a code reader on the OBDII port to see if there were any codes showing up, but there were not. I turned it off again and let it sit about 15 minutes, after which the icon had disappeared when I restarted. I tried restarting it to see if the warning icon had disappeared, but it was still there. Coolant level in the overflow tank was fine (right near max), no signs of leaking, fan running as I would expect. I pulled off the freeway as soon as I reasonably could and checked under the hood for anything unusual. This Saturday when I was driving on the freeway (conveniently around two hours from home, early in the drive to take my daughter to college.), I suddenly got an audible alarm and a red box saying "Engine Coolant Overheat." There were no other accompanying symptoms (engine running fine, no unusual noises, etc.). I have a 2014 Ford Fusion Energi Titanium with about 116,000 miles on it.
