Well installed the charger everything is cool. no leaks.

Now about half way up to normal operating temp my check engine light comes on. and the temp gauge drops down to 0 like its dead. So I replaced the thermostat still does the same thing. Does anyone have idea's on what I can check?

 

Open or short in engine coolant temperature sensor circuit, or engine coolant temperature sensor. Manual says to use scan tool to get engine coolant temp. -40 = Open Circuit, 140 + = short circuit.

Don't know if this helps or not??

Sounds like you either knocked off the sensor ir maybe pinched the wire while installing the charger.

 

Where is the wire/sensor? So I can check it out.

So that sensor would be called Temp sensor? or whats the correct name for it so I can find it in TIS.

Thanks LMS if you like give me a call 702-376-1114

 

Honestly I dont know exactly where its at on this car. i've never looked before.
It SHOULD be on a water pipe somewhere.Look anywhere where there is coolant running through it.
Ford calls it a coolant temp sensor.Once you find it try jiggling the wire maybe its loose.Look for any obvious pinch marks where it might have gotten pinched or sometimes the wire itself can break inside the insulation.
Or maybe its just a weird coincidence that the sensor went bad right about the same time you were working on it.

 

OK cool thats fixed

Thanks

 

I'm having the same code come up on the climate self diagnosis. Did you find the sensor or wire? If so where was it located?
