2017 CHT Sensor Replacement

[yeffaham]

Hi all, I just got a P1288 code on my 2017 Expedition so I was looking to inspect the wiring to the CHT sensor and possibly replace it. I've read that for the F150 you can access this by removing the passenger fender liner so I tried that but can't seem to reach to where the sensor is largely because of the air conditioning lines to the rear AC.
I'm looking for any suggestions on how to access that sensor.
