My wife's daily popped the dreaded P0016 code last night. It is a 2015 sport and has 58,500 miles. I cleared it and it was back again this AM. Thanks to some research from this forum, I quickly learned this is likely NOT a sensor and more likely to be a stretched timing chain. I have the cold start "rattle" as well.
I made the first available appointment with my only local dealer which is not until next week. Hoping (based on the information from here) that the entirety of repairs will be covered under the power train warranty.
A few questions:
1. The F150s have a TSB for this. Is there one for the explorers?
2. If no TSB do i have leverage to ensure they do the tensioners and phasers as well? I would hope they do, but i am new to this area and have no rapport with the local dealer.
3. I saw the recommendation to do the water pump as well. Thats great advice, and I will ask to pay out of pocket if necessary to ensure it gets done while everything is apart.
4. Any other recommendations? I am a little concerned they just throw a new cam sensor in, but it appears if the chain is stretched the CEL should return quickly even with a new sensor.
Any other advice is greatly appreciated. Thanks to all for the help and support.
