Looking up info right now for you,
This is the Ford part number for the CHT sensor and pic1 9L8Z6G004C
This is the coolant temperature sensor part number 4L3Z12A648AB
They both look similar. I will keep looking for more info
If you look at these codes too, they don't really refer to two different sensors,
The p0119 refers to a circuit problem, and if there's a wiring issue, which means the ECM is getting an incorrect reading, this is leading to the p0128 code. Thats why I was wondering if the CHT had five volts on one wire while unplugged. It doesn't say coolant sensor, its saying that Temp sensor circuit has an issue. I don't think your vehicle has both sensors, I haven't found any diagram that lists both sensors.
I've been looking in numerous places for 3 days now and have not seen one with both sensors. This P0119 says that the circuit intermittently became open or shorted while the vehicle was running. Thats what set this code. So, if there's a contact point where the harness is rubbing threw and touched ground for a second, it will set this code. Engine vibrations cause this type of thing. Checking contact points of the harness is usually how these type errors are found.
I'm reading this can be caused by trapped air in the coolant system as well.
It is also possible that they gave you the wrong part, and you put a ETC sensor in where a CHT sensor goes. Did you go to AutoZone or an aftermarket parts store?
