2021 F150 5.0 Cylinder Deactivation

sure wish we could just go back to good ole reliable trucks that didn't have technology telling it how to run or when not to run. too many options creates too many problems

Thank the government, they even screwed up gas cans

Exactly why I drive a tundra.

We have (4) 5.0 fords in our fleet, 2 of them needed intake work with less than 60k. Will see how these 5.0s with 10speed hold up.

Chevy had alot more issues with deactivation then running the same 4, same as ram hemi. You run into lifter issues, which will eat away at the cam.

Tina had that issue with her 2012 Yukon.

Thanks for the info. I was an unwilling participant in the Chevy R&D program. I owned a 6.5 chevy diesel. I don’t care to join the Ford program.

Fords have been deactivating cylinders for years.........

My 5.0 had a cylinder deactivation @ 72,000 miles. Misfire on cylinder 5 turned into a 30 day head replacement @ Gullo (mine is a 2013)

13’ 5.0 isn’t deactivated

I have heard that simply plugging a connector into the 7-pin plug will deactivate the Start Stop by tricking the truck into thinking it's towing something. I was planning to grab a $6 plug off Amazon and see if that works.

There’s an easier method that doesn’t cost a dime and doesn’t trick the truck into thinking it’s towing a trailer which makes the reverse camera not work and could potentially alter the shift points.

But you have to plug it back in to tow or trailer lights wont work.

I think he's saying that one of his cylinders went tango uniform and required a lengthy and costly repair that was not designed into that engine.....

Exactly, I was just being a smart •••. Low compression on cylinder lead to intermittent misfire.

I've got the '18 5.0L and love it...only thing that annoys me is it uses the "Start Stop" technology...but it has a button to over ride it....I override that 90% of the time...they do sell a harness to plug in to permanently override but I'm too cheap...100$ for that harness

You can unplug a wire from the driver side floorboard area and you don't have to push the button to de-activate it. Just need to plug it back in before you haul a trailer.
