Question

I have two codes p1289 & p0119 , engine light on , ford expedition 2006 eddie bauer

Answer 1

P0119 Engine coolnat temperature sensor 1 circuit intermittent / erratic

P1289 Cylinder head temperature sensor (CHT) circuit high condition

Make sure there is no coolant leaks, and that the operation of the cooling fan is working, when the engine is at operating temperature and not over heating. With  the engine off, the cooling fan should have resistance in the direction of its movement. If this condition is just  sensor problem you would have to remove the intake to change the sensor ,
