First time poster and listener as this issue with my 2014 Edge SE is about to drive me insane and led me here.
Rewind 2 weeks ago, driving along and "engine coolant over temp" popped up on the dash along with cooling fans kicking on. Great. Arrived home and started trouble shooting the next day. Coolant levels looked Ok. Only code showing is P1289. Another symptoms was temp gauge on dash showing normal operating temps and immediately after warning pops up, the bottom bubble of the thermometer image is colored in (like its not registering).
Upon Google search, all signs were pointing to cylinder head temp sensor being bad. I normally perform most of the work myself on vehicles, but I did not want to tackle this project after watching the video on getting to the sensor in the valley. Don't have a mechanic handy so called the dealership. ~$600 to change it out. Fine. I just need to get it fixed.
Just received a call stating they traced it down and the camshaft sensor is bad. Confused, I asked again. Quoted $1200 to fix it. Told them I'd be by to pick it up. Even more confusing is the videos I watched were 1/10th the effort to change out the camshaft sensor in comparison to the CHT sensor, but double in price.
Long story short, if you're still with me, I've googled far and wide to no avail relating my symptoms and P code to a camshaft sensor. I know just enough about engine repair to get by, but can anyone with expertise see any relation between their diagnosis and my symptoms? Any insight would be GREATLY appreciated.
