Mini Paceman Oxygen Sensor Issue

My 2014 Mini Paceman exhibits symptoms indicative of an oxygen sensor malfunction. Specifically, an error pertaining to the oxygen sensor heater circuit is logged, the malfunction indicator is illuminated, and a discernible increase in fuel consumption is observed. Preliminary assessment suggests a potential defect within the cable or plug connection. I welcome insights or shared experiences.

Whoa, oxygen sensor issues are a pain! I had a similar problem with my old Peugeot – check engine light driving me nuts and the fuel consumption was awful. Have you tried sensor testing or checked the exhaust system for leaks? It might be something simple before you start replacing parts.

Concerning your experience with the Peugeot, could you elaborate on the specifics of the fault and any diagnostic steps undertaken?

Right, the Peugeot's malfunction indicator lamp lit up, and the error pointed to a heater circuit issue as well. I tried sensor testing myself, but it was beyond my abilities. I would recommend that you consider visiting a workshop.

Diagnosis confirmed a defective heater element within the oxygen sensor, accompanied by a corresponding fault code. Replacement completed; total expenditure amounted to 95€.
