Help! My wife's truck keeps dieing on her. 15 platinum with ecoboost. While driving, Hill start assist, advance Trac, and other warnings come on but no engine light. The truck shutters violently then looses power. Turn the truck off then starts up again. Dealer said it was something with the gauge cluster that needs to be replaced...sounds suspicious after reading posts from people with similar issues saying throttle body or other sensor. Any ideas?

 

Throttle Body

 

I had the same thing happen in September on my new truck. The warnings went away and never came back after it sat for a while.

 

X2. the gauge cluster alone wouldn't cause your symptoms

 

Throttle body. Same issue with my '15 3.5. $100.00 in parts and maybe 30 minutes of diy labor and life was whole again!!

 

My buddies truck had the exact same issue. Throttle body as mentioned above

 

Hill Start, AdvanceTrac, Descent Control, Sway Control, ect... all are features that need throttle position data to do their jobs. When that data fails to match other inputs (Ex. throttle sensor says the throttle is closed but MAP says you've moving a lot more air than you can at closed throttle), those features are disabled. When they get disabled, they all send out notifications.

That tech thinks the notifications originate in the gauge cluster, and it's bad. They do not, and he's the thing that has gone bad.

 

The difference between a tech who actually knows how things work and can troubleshoot the root cause, and a tech who replaces parts in accordance with the maintenance manual until the problem goes away.

 

Nah it makes sense. If CEL comes on, replace the bulb. Must be a faulty bulb . . . .
