Clio Oxygen Sensor Heater Error

Hey, I had a similar issue with my old car! Check that the sensor's cable and plug are in good shape. Sometimes they can get loose or corroded. Is it just the light, or are you noticing any rough idling or anything?

Thanks! I'm not very technical. Could you explain what I should look for when checking the cable and plug? What kind of damage or disconnect should I look for?

Basically, see if the wires are frayed or broken near the plug. And check if the plug is firmly connected to the sensor. If it all looks good, the sensor might be faulty. You could try testing it, but honestly, that's a job for a workshop.

The cable to the oxygen sensor was worn, just like you said. A local workshop replaced the faulty cable and plug for 95€. The check engine light is off, and the Clio is running well again. Thanks!
