2012 Rio with check engine light possibly related to Eco button

Asked by Jun 02, 2017 at 03:49 PM about the 2012 Kia Rio

Question type: Maintenance & Repair

I have a 2012 Kia Rio with 80,000 miles and no problems. Last week I
decided to turn on the ECO button and a few days later my check engine light
came on. I went to get the light checked at auto zone and they said it was the
knock sensor. I have a warranty but can't get in until next week to figure out
what's going on. Has anyone else had this problem or one similar?
