2010 Taurus SHO cylinder head temperature sensor location

[2010TaurusSHO]

I have a 2010 Taurus SHO with the 3.5 Ecoboost engine. About 103k miles on it.

Recently I was going through a drive thru, and I realized the coolant temperature gauge in the gauge cluster was maxed out all the way to HOT. Shortly after I realized that, the warning chime started.

So I pulled over and shut the car off. About 5 minutes later I turned the car back on again and the coolant temp was at 3/4. I just drove it back home. On the way home, the coolant gauge read completely normal, even when I stopped at big intersection stop lights.

Once I got home, I opened the hood and checked the oil level and coolant level. Everything was normal. Also, there's no engine lights or codes.


What do y'all think about this? What could be wrong?


I dont think the car actually overheated. I think the engine was at it's normal operating temperature in the drive thru. Thermostat and water pump was replaced about a year ago with OEM FoMoCo parts, so I'm pretty sure those aren't what caused this whole issue.


After doing some research, I think the problem with my car is the cylinder head temperature sensor malfunctioning. It's 13 years old so I'm pretty sure it's had enough.

Does anyone know where the Cylinder head temperature sensor is located on a 2010 SHO 3.5 Ecoboost? Is there a "procedure" that must be completed after the sensor gets replaced? Does anyone have experience replacing one of those sensors?

Thanks in advance

see if you can find a diagram. I would pull codes and see what they say before I pulled the trigger

Cooling fans working?

the usual culprit for a CHT sensor is chewed up wiring, not actually a faulty sensor. have increasingly seen this, soy based insulation attracts them.

def check fan operation as well.

Item	Part Number	Description
1	14A464	Cylinder Head Temperature (CHT) sensor electrical connector
2	6G004	CHT sensor
3	W503274	Ground wire-to-engine front cover bolt

1. Remove the Air Cleaner (ACL) outlet pipe and the ACL .
2. Position the ACL -to-RH turbocharger intake tube aside.
3. Remove the ground wire-to-engine front cover bolt.
4. Disconnect the Cylinder Head Temperature (CHT) sensor electrical connector.
5. Remove and discard the CHT sensor.
   • To install, tighten to 10 Nm (89 lb-in).
6. To install, reverse the removal procedure.
   • Do not reuse the CHT sensor. Install a new sensor.

That you all for the help. The cooling fans do work.

Really really appreciate your help. I just got a cylinder head temp sensor from the parts department at a ford dealership I work at. Got the OEM cht sensor. Planning to replace it myself pretty soon.

I've been trying to find the location of this sensor on a '14 I just picked up, and this is incredibly helpful. Seems to be so little info on the 3.5EB in these since it only came in the SHO.
I found my problem, wires are cut/chewed right behind the sensor, do you know offhand where it should be connected to? I will dig into it tomorrow, but I have no idea where to look for the other end.
Thanks!

I had the same issue with my 2010..Ended up being a bad fan module.

Touche mine was bad fan module.
