I have to swap these out so I can have an accurate temp gauge and no more check engine light. Where are these?? Pictures would greatly be appreciated or a very in depth description of the location

2003 4.0L:

Find the thermostat housing and go back maybe 3 inches under the upper intake - might be more easily seen from the passenger side. You should find two devices that measure Engine Coolant Temperature.

Grey connector:
ECT Sensor
light green/red and grey/red wires.
Measures ECT for the PCM

Brown connector:
ECT Sender
red/white and black/white wires
Controls the temperature gauge in the IP

 

OKAY :), thank you very much for your patience..... I couldn't find them before because that black 4.0L plastic cover was hiding them.

 

I have a 2003 2.3l ford ranger and the ECT is unplugged and I can't find the port where it plugs into
