Yeah, I visually inspected the wiring. Everything looked okay, but you know how that goes. Did you end up replacing your O2 sensor? Or was it something else causing the error?

In my case, the issue was indeed the oxygen sensor. Given your symptoms and troubleshooting, it's likely the culprit. I'd suggest getting it checked at a workshop to confirm. It's better to be sure before replacing parts.

Thanks! I appreciate the input. Took it to the shop, and you nailed it – faulty O2 sensor. New one installed, error cleared, and she's running like a champ again! Cost me 95€, not bad!

I had similar symptoms on my Territory. An oxygen sensor issue can definitely cause those problems. Have you checked the sensor's wiring and connections for any signs of corrosion or damage?
