I have a 2006 ford expedition 5.4L king ranch and i cant locate the coolant temperature sensor i been receiving code p1289 changed the cylinder head temperature sensor twice with the harness and connector reset the computer but still getting engine temp data error on dash with check engine light and p1289 and now also p1000 please help!!!!!

 

Your engine does not have an engine coolant temperature sensor.

 

P1289 FORD - Cylinder Head Temperature Sensor Signal Greater Than Self-Test Range

Possible causes
- Wrong thermostat
- Not at operating range
- Engine overheated
- Low engine coolant level
- Faulty Cylinder Head Temperature (CHT) sensor
- Cylinder Head Temperature (CHT) sensor harness is open or shorted
- Cylinder Head Temperature (CHT) sensor circuit poor electrical connection

P1000 means all sensors are not ready, you will get this after a reset till drive cycles are complete.

 

I read the manual and i was expecting a diagram of the engine with the sensors but ford is trying to sell me this part saying it might help i changed yhe cylinder head sensor twice and the connector with wires to the sensor and still getting the engine temp data error on dash board with p1289 and p1000 codes.

 

The P1000 will go away when all monitored sensors achieve readiness. The ones for the evap system take some time to do this, it's dependent on several drive cycles.
