I have 2019 Ford Escape 1.5L Ecoboost with an engine light on for faulty heat sensor 1 bank 2 which is the downstream sensor. I am looking to see if anyone has any guidance or diy steps to replace it. I crawled under and that sensor is very hard to get to and I am not sure where to start. I've seen several youtube videos and they made it look easy but none shows what they removed in the beginning to get to the sensor. Any help is appreciated!
