Head temp sensor on a 2000 linclon navagator 5.4 not under intake where it says it is can someone help

This engine does not have nor use a engine coolant temp sensor. It uses a cylinder head temp sensor. It is mounted under the intake which has to be removed to gain access to the sensor. It is on the drivers side head next to the intake ports

Temp switch - Under hood, center, upper engine area, front of intake manifold, driver side of distributor, mounted in engine block,
Coolant temp sensor - Under hood, center, front engine area, passenger side of distributor, mounted in intake manifold,
There is no water sensor

the coolant temp is measured by the cylinder head temp sensor , located under intake manifold



this is for the 3.9 litre on the left bank , the 3 litre is on the right bank

CHT -cylinder head temperature sensor located under the intake manifold.you have to remove intake manifold to replace sensor its in the cylinder head.

mass air flow sensor or the throttle body needs to be cleaned .first take the intake hose of the throttle body and spray the inside the the throttle body with throttle body spray. there is a pin hole under the flap or the butterfly that lets a little air in make sure that is allso cleaned out. let it sit and see if that fixes it. if not (MAS )sensor would be my next guess.

What you have is a head temp sensor, which is screwed in between 2 injectors. Thanks for using FixYa.

CHT-Cylinder Heat Temperature Sensor

V6--Driver Side--between COP Coil 5 & 6

V8-work in progress & I own one

NO CTS Sensor,odd I know

two or three. one for the idiot light, measures coolant temp. one for the pcm and the gauge. measures coolant temp also, one for intake air temp, locater on intake snorkle. this obviously measures temp of intake air. the latter two help pcm control fuel mixtue, timing and the like.

The engine coolant temp sensor is in the cyl head that tells the computer the engine temp.

the intake air temperature sensor is located inside the air intake duct which is where the air filter is located pull the rubber tubing off the throttle body and look inside with a light and you will see it
