I have a 2005 Mustang GT. I got a code P1289 which says Cylinder Head Temperature Sensor. Have no trouble finding the part, pretty inexpensive. Now I just need to find where it is located in my engine. I have Googled till I am blue in the face trying to find the location in my 4.7. How hard is it to change out? I have to do it myself as the IRS got my money this year and mechanics don't work for free. I've watched video on how to change it out on other cars, it looked simple....but not sure if it is on this car.
