Partner oxygen sensor heater failure

I had a similar issue with my Opel Astra. Same symptoms - check engine light, oxygen sensor error. Did you check the wiring and the plug connection to the sensor? That's usually the first thing to check.

Thanks. Can you tell me more about how you checked the wiring and connection? What should I look for?

I visually inspected the wiring for any damage, like cuts or frays. Then, I made sure the plug was securely connected to the sensor. Honestly, I didn't get very far before taking it to a workshop. It's probably best to get it checked by a professional.

Thanks for the advice. I've inspected the wiring as best I can and found nothing obvious, so I think I'll visit a workshop. The estimated repair cost I received was around 95€. I'll post again if that fixes the problem.
