Whats wrong with my 05 Expedition EB 5.4 Triton motor?

Question

I have no air and I'm getting the p1289 and p0119 I have an 5.4 Triton motor

Answer 1

P0119 Engine coolant temperature sensor Circuit intermittent  /  erratic

P1269 Cylinder head temperature (CHT) sensor circuit high input

With these code you will not have the air condition , There are 2 area that you have to be concerned, the CHT sensor is circuit high , circuit high code condition means there is no connection to that sensor, if the connection are present and there is no open along its harness you replace the CHT, Having a engine coolant temperature sensor erratic, check the radiator fluid level , any loss of fluid in the radiator will cause the engine to run hot. The coolant leak has to be inspected and the operation of the cooling fan

​ A malfunction of the cooling fan clutch will allow the engine to overheat

​ A P1299 mean the CHT is not connected, that or its is a failed CHT sensor, Located under the intake manifold
