Engine Mechanical problem V8 Four Wheel Drive Automatic

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.
Do you
have the same problem?

Hello,

The coolant temperature or cylinder head temperature sensor is located near the rear of the engine, Here are some diagrams (below) that will show you where they are.

This guide will help you see what you are in for when doing the job step by step.

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

That 's because it doesn't have one it uses a cht sensor instead.

Hello,

The engine coolant sensor is located near the front of the engine on the drivers side. Here is a guide that will give you an idea on what you are in for when doing the job.

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

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

Computer said my coolant temperature sensor was bad. I purchased one. Have looked at many diagrams for location. I removed alternator and took out sensor behind thermostat housing and below about a foot towards center of motor. Have done small jobs before but cannot find this one. Thanks for help! The sensor I took out is much smaller in diameter at the threads than my new one.

Just make sure you got the correct sensor and am looking in the correct location. I have run into this many times with people not getting the correct sensor. This engine has a Cylinder Head Temperature sensor and a lot of stores will not look this up correctly.

There's a whole bunch of problems here. The first one is there is no drawing that shows the location of the coolant temperature sensors. There is a cylinder head temperature sensor indicated at the bottom / center of the first drawing. They do make reference to two other coolant temperature sensors, but they aren't even shown on the electrical diagrams. At this point I can't show you were they are, but you will usually find them close to the thermostat housing at the end of the upper radiator hose. On V-type engines, you might also find them on the intake manifold. With inline engines, they might be found on the side of the block.

The next problem is there are usually two of them. One is for the dash gauge and will have just one wire connected to it. The other is for the Engine Computer and will always have two wires. Ford did have a lot of trouble with the two-wire sensors in the early to mid '90s, but other than that, temperature sensors have an extremely low failure rate because there's just one component inside them. It's much more common to find spread or corroded connector terminals that aren't making a solid connection.

The last concern is the diagnostic fault code did not say to replace the sensor or that it was bad. Fault codes never say that on any brand or model. They only indicate the circuit or system that needs further diagnosis, or the unacceptable operating condition. First we have to rule out wiring and connector terminal problems associated with that part. Also, there are many fault codes that can be set related to temperature sensors, and they mean very different things. What was the exact fault code number you're diagnosing?

My truck has high idle for 15 to 20 minutes. There are no codes at all. It seems may be related to coolant temperature sensor. I know where the cylinder temperature sensor, but I'm having a hard time locating the coolant temperature sensor.
I found some people talking about it possibly having a thermostat instead but I'm not sure. Would there still be a sensor?

Good afternoon,

Why do you think it is the coolant sensor? It does not control idle speed.

https://www.2carpros.com/articles/how-to-replace-an-idle-speed-control-motor-iac

You said you knew where it was but you want to know where it is? Please explain.

The sensor is located just under the intake manifold on the left front of the engine.
