Seat Exeo Oxygen Sensor Issue

I'm tearing my hair out! My 2013 Seat Exeo with a gasoline engine is giving me headaches. The check engine light is on, and I pulled the error memory – it says something about an oxygen sensor heater failure. It's got 142053 km on the clock. I'm guessing it's got to be a bad connection somewhere in the cable or plug, but I don't really know where to start looking. Any thoughts? I am scared of malfunction indicator and vehicle emissions issues.

Whoa, that sounds eerily familiar! I had something real similar happen with my Exeo. Check engine light and all. Is your fuel consumption higher than normal? I'm no expert but are the car components running as expected?

Yeah, the fuel consumption has definitely jumped up. It's burning more fuel than usual. How did you know about the oxygen sensor heater exactly? Did you also get an error code relating to vehicle emissions?

My Exeo was doing the EXACT same thing! Check engine light, the works. Turns out, the heater element in the oxygen sensor was kaput. I'd say get it checked out at a workshop, just to be sure. I was also thinking it can be related to older car components.

Okay, I really appreciate your help. I took it to a local mechanic, and you were spot on! It was the oxygen sensor heater. New sensor installed, error gone, and she's running smooth again. Cost me 95€, parts and labor included.
