need to find the location of the temp sending unit. My check engine light is on due to this sender not functioning correctly. 2004 f150 new style and mine is on the front of the engine block on the bottom. Seems like mine is a 2004 1/2. Like to have never found it and they kept trying to sell me the wrong one. It is smaller than the parts house tried to sell me. It is underneath, bind radiator on front of block.

2000 Ford F150 V8 Four Wheel Drive Automatic

where is the coolant sensor on a 5.4l engine. I found the what I believe is the cylinder temp sensor by the alt. In the driver inside head. I am not showing any temputure on gauge ( top hose is hot), and the engine is runnning with high rpms. Truck starts fine when cold, but when warm, have to hold pedal down ( like it is flooding), then runs at 1500 rpm in netrul.

The book is correct; however, if it isn't there, check on the cylender heads.

Hello,

If you follow the upperradiator hose to the engine it will be located within a few inches of the thermostat housing it may also be located in the thermostat housing.

Computer problem
2001 Ford F150 V8 Four Wheel Drive Automatic 143000 miles

My check engine light came on. The mechanic did a diagnostic check and determined the water temperature senser to the computer was bad. I bought one at NAPA and figured I would put it in. The problem is I can not locate the senser. I thought it would be located next to the thermostat, but it's not. Do you know where this senser is located?

Your engine doesnt have a traditional ECT(engine coolant temperature) sensor, instead it employs a cylinder head temperature(CHT) sensor.

My 2003 ford f150 6cylinder is putting out a code p1299, I would like to know where the cylinder head temperature sensor is located, chances of it failing and if this part is called by any other names. The truck seems to be running fine, this has happened once before when it did the temp gauge peggedall the way hot and the truck switched to alternating cylinders I belive but after stoping the truck and restarting it it seemed to go away, this time none of this has happened and would like any advice that could be helpful. So far I have been told to burd the coolent system
