Hello everyone, I joined to see anyone might have some input on an issue I'm having with our 2016 sport. A few ago it popped up with a crankshaft position sensor code. Replaced it with part directly from Ford. Issue came back a few days later, called the shop this time. Every diagnostic test ford recommended, it has passed but continues to intermittently shut off or drive VERY poorly and continues to throw the same CPS code. Has anyone had this issue before? I'm at a loss and so is the shop. Any insight would be greatly appreciated. TIA!
I'm currently having what sounds like the same issue with a 2016 Platinum. it started with the car running rough, getting into limp mode and then shutting down completely. Towed to the dealer, replaced the fuel pump. Didn't fix it. Returned to dealer, they said they found an intermittent CKP failure with a small short to ground on the cabling at the firewall. "Fixed". NOT.
Car exhibits smooth idle with no codes. In park, running the RPMs up to 3k smoothly or quickly produces no engine issues. However, when on the road under any acceleration, the engine surges (small surges at slow accelerations, big surges at with quick acceleration). I am noticing the tach bounding around a lot, and not always in sync with the surging. When approaching a stop sign while coasting, the tach and engine run smooth.
Through all of this, there have been no codes, other than the P0339 the dealer said they found. I've never seen it.
I think its the crankshaft position sensor. This has already cost me $1600+ for the unneeded fuel pump. I'm not looking to throw major parts at it again. It has left the wife stranded twice now, and she refuses to drive it. I don't blame her.
I'm looking for a CKP replacement procedure but not having much luck with the You tube or anywhere else.
Any help would be appreciated. As soon as this gets fixed, the car is gone.
