I Have not been succefull in locating the sensor and have not been able to find a diagram that shows the 4.6 Northstar motor with the sensor on it.

I have contacted Just ask.com and was sent three diagrams not matching what i have.

I was told that it may be located under the EGR valve which i believe have located.

if i am siting in the drivers seat it would be directly in front of me low enough on the motor that i cannot lay eyes on it.

Please Help! lol

does anyone know the replacement cost for a mechanic to do it?

The Haynes manual which i paid for also does not have his year make or model. every procedure manual i have seen so far does not have a definitive procedure for this car. Is there is one? please help.

I love this car and it's never had an oil leak and has never overheated.

It would be a crime to take her out back and put a bullet in it just because I cannot seem to do such a simple thing.

Thanks

Good afternoon,

I attached two pictures for you to view of the location. It is on the back of the cylinder head. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
