Toyota iQ O2 Sensor Issue

Hi, I have a 2011 Toyota iQ with a gasoline engine. The check engine light is on and the error memory says something about the O2 sensor. I've also noticed higher fuel consumption. Car has 61838 km on it. Could it be the O2 sensor, or is there something else I should check?

A 2011 Toyota iQ owner experienced a check engine light and increased fuel consumption, suspecting an O2 sensor issue. A suggestion was made to check the cable and plug connection to the O2 sensor, as a defective connection could cause these symptoms. The owner took the car to a workshop, where it was confirmed that the problem was indeed a defective connection, which was then repaired.

Did this summary help you solve your problem?

I had a similar issue with my iQ. Have you checked the cable and plug connection to the O2 sensor? A defective connection can cause those symptoms.

Thanks for the tip! Where exactly is the plug connection located? And how would I check it? I'm not very experienced with car repairs.

It's near the catalytic converter, but honestly, if you're not familiar with it, I'd suggest taking it to a workshop. They can diagnose it properly and check the sensor itself. Could save you some headaches.

Alright, thanks. I took it to the workshop, and you were right, it was a defective connection on the O2 sensor. Repair cost me 95€ Thanks for the help!
