Coolant temperature sensor location for replacement?

Good morning.

It is located on the driver side head at the front by the alternator under the intake manifold. Here are both location in the diagrams below it is a two wire sensor that just screws into a coolant passage. The diagrams and instructions below to show you how on your car. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

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.

Here is the diagram (BELOW)

Hello. I'm Harry. I've dug around and I think I've figured out the source of the confusion. Ford calls it a Cylinder Head Temperature Sensor while AllData goes back and forth between that name and the more generic Engine Coolant Temperature Sensor. That seems to make it appear that there are 2 such sensors. What I've uncovered is that there is just the one sensor. I'm including the requested information in the attached images.

Hopefully that should shed light on what you're trying to do. Good luck and let us know how it goes.

Hello again. Sorry about that. Guess I clicked the wrong year and didn't catch it. Good news though it's that the information does still apply. I looked up the 2004 truck and am attaching the info in case someone else needs it and comes across this thread.

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.

It uses the info from the main temp sensor called the Cylinder Head Temp sensor and gets the data from the PCM.

Good afternoon,

The cylinder head temperature sensor is for the gauge. I attached the procedure and an explanation for you of the sensor and what it controls.

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?

Hi KASEKENNY1. Looks like we found the same diagrams.

This is not uncommon on these engines. The reason is, it is called a cylinder head temp sensor so when you are searching for it under ECT sensor in any manuals it doesn't pull anything up.

Here is a guide that will help with this in general:

Below you will find the process from the manual on this. let us know if you have other questions. Thanks
