Ford Flex knock sensor connection

Hmm, knock sensor issues can be tricky. You're right, the symptoms line up, but have you actually tested the sensor itself? Or just visually inspected the wiring? Could be something else triggering those symptoms too, you know. Is the engine pinging or knocking audibly?

Good point. I haven't actually put a multimeter on the sensor itself yet – mostly focused on the connections 'cause they looked a little dodgy. What kind of readings should I be looking for, generally speaking, to confirm a dead sensor? Or is it even worth digging that deep before just swapping it?

Without the proper diagnostic tools, getting precise readings can be tough. Given you've already got suspicions about the wiring and the symptoms are persistent, and if you lack the tools, I'd say bite the bullet and get it checked by a pro. Could save you some headaches in the long run.

Yep, you were right. Bit the bullet, took it to the shop. Turns out it WAS the knock sensor connection. 95€ later, all fixed. Thanks for the reality check!
