Rifter Knock Sensor Fault

Alright, mechanics, I'm hoping someone can help. My 2020 Peugeot Rifter, gasoline engine, is throwing codes and acting up. I'm at 202677 km. The check engine light is on, my fuel consumption has definitely gone up, and the idle is rough. I scanned it and it's showing a knock sensor fault. I checked the visible wiring and the plug; they look okay but who knows? Anyone else seen this on a Rifter?

I had something similar happen on my Rifter – not sure of the year but it sounds familiar. Engine knock, warning light, the whole nine yards. At first, I thought it was bad gas, but the problem persisted. Higher fuel consumption as well. Did you clear the codes to see if it comes back?

Yeah, I cleared the codes, but the malfunction indicator came back on after about 50 km. That's what's making me think it's not just a fluke. The uneven idling is bugging me as well. What did it end up being for you, and how much did it hurt the wallet?

Sounds identical. I thought I could troubleshoot it myself, but in the end, it needed a new knock sensor. Since the error reappeared after deleting it, I recommend checking it out in the workshop. They'll be able to test the cable properly and, if necessary, replace the sensor, and adjust the ignition timing. It might just be a defective connection. If it's just that, you might get away with around 95€.

Thanks for the info! Sounds like chasing the connection issue is the place to start, but a trip to the shop is probably in order. Appreciate the help!
