Hello, I have a 2008 Edge SEL 3.5 and it recently overheated and got a P1299 code. It lists possibilities as 1. Low engine coolant, 2. Drive belt off, 3. Failed cylinder head temperature sensor. The first two are not the issue, I am trying to locate the cylinder head temperature sensor (CHT) but cannot find it. Does anyone have a diagram or know the exact location of the sensor? Thank you so much.
