The same problem am facing on my auris hybrid 2013 model 48k miles only … diagnosed complaints O2 sensor …. My question is Must to Airflow sensor also ??? Along with O2 sensor
Hi Paul, Not necessarily, only change the Mass Air flow sensor if the diagnostic shows the code and says to replace it. In my case, The codes were showing for both 02 sensor and Air Mass Flow sensor that's why I changed them both at the same time. The sensors are not expensive anyway for 02 sensor it's about £15 to £20 on eBay and A/M/F/A it's about £35 to £80. Hope it helps. And good luck 🤞
