Ford Mechanic: roy, import/domestic specialest replied 1 year ago

how do you know it is not overheating??? the heat sensor is doing its job protecting the engine from damage and the gauge is verifying it is hot

We install the the sensor tonight and the car is started right away but I thought a couple minutes the needle thing went up in the engine shut off so we wait a couple more minutes we started back up the car enough that a little bit it happened the same thing The AC is not working but the cooling fan runs all the time a high-speed
We looked everywhere we couldn't find it temperature sensor like other vehicles so I was told that this going to be cool it doesn't use a temperature sensor is only they had temperature that works as both

Hello, you replaced the cylinder head temperature sensor? How many miles are on the vehicle? Do you have good heat when you turn the heat on? Full of coolant no leaks? Can you post the 17 digit in number so I can check a few things?

Ok does the engine run long enough for it to reach normal operating temperature or does it shoot right up to overheat? No codes stored in the PCM? Do the heater hoses get hot?

Ask Your Own Ford Question
Customer reply replied 1 year ago
we drive it for a while but it only goes from bring all the way down to all the way up all of the sudden
And when that happens is when the engine dies
We got it to work by bypassing the connector with a wire but the indicator stays down all the time but Ac don't work and fan runs high all the time
Yes the hoses get hot
Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 1 year ago

Heater hoses hot should have heat, no codes stored in the pcm if checked for codes?

Ask Your Own Ford Question
Customer reply replied 1 year ago
Ill take to the mechanic to see what code comes on ill let u know
Any idea what could be the problem so far ?
Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 1 year ago

Either a shorted circuit for the cht sensor causing the gauge to raise be one thing but the lack of heat could be an issue with a blend door motor if the hoses are hot.AC will be disabled if engine is running hot according to gauge and cycle fans on

What's the cht sensor ?
Is there an actual temperature sensor in this car ? I've looked everywhere and that's the only only I found , is located between the cylinders
I really need the solution to this problem thou
Tell me what can we do or try ??
Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 1 year ago

Normal Operation

The PCM uses the Cylinder Head Temperature (CHT) sensor to measure the engine temperature. The Instrument Panel Cluster (IPC) receives the engine temperature data from the PCM over the High Speed Controller Area Network (HS-CAN) communication bus. The IPC monitors the engine temperature data received from the PCM and commands the temperature gauge indication with a corresponding movement of the pointer.

The non-hybrid and hybrid temperature gauges appear differently but essentially function the same. The non-hybrid gauge is an analog gauge with a needle that points to a specified area of the gauge depending on the data received from the PCM. The hybrid gauge is a digital display that appears as a thermometer. The fill color of the thermometer is blue when the temperature is between the cold and normal ranges. When the temperature indicates an overheating condition, the fill color turns to red.

Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 1 year ago

Ok for one if you didnt know this vehicle has a branded title, meaning it has been probably in a major wreck and reassembled. Carfax can tell you more regarding that, there is a technical service bulletin im attaching mentioning corrosion inside the cht sensor connector and how to inspect& repair if needed.

Ask Your Own Ford Question
Customer reply replied 1 year ago
There is no sign of corrosion or water in the CHT it's all clean
Ford Mechanic: HDGENE, Ford Senior Master/Diesel/Trans replied 1 year ago

Then with a new sensor installed and verifying the engine temperature isnt actually overheating. Since its a branded title, there is a possibility of a wiring issue with the vehicle. You should run your own wiring from the CHT sensor to the PCM to eliminate a wiring problem. If it still does the same thing bypassing the harness, it would be an issue with the Powertrain control module itself. If the engine is actually overheating as the temp gauge says it is and the cooling fans are working it is a possible issue with the water pump impeller damaged and not circulating water properly. Im thinking its more of an electrical issue. The blue wire is the signal return for the sensor pin 39 to the pcm. SInce the green wire to the sensor is supply power for other sensors and not flagging other codes I dont suspect that being an issue but you can jump from one of the other sensors to the green wire and return wire to the pcm to see if it changes operation.
