GT86 check engine light and knock sensor issue

Hey, my 2019 Toyota GT86 with a gasoline engine is throwing a check engine light. Mileage is at 56933 km. I've noticed higher fuel consumption and some uneven idling too. Suspect it might be the knock sensor. Anyone else run into this?

I had similar symptoms with my GT86. Have you checked the knock sensor's cable and plug connection? A defective connection can cause these issues and trigger the warning light. Ignition timing could be affected.

Thanks! I'll check the cable and plug. Was that the actual problem you experienced, or was there more to it?

Yes, for me the problem was a corroded connector on the knock sensor. However, if cleaning the connector doesn't solve the issue, I would strongly recommend having the sensor checked at a workshop. Continuing to drive with this issue may cause poor performance.

Thanks for the insight! I'll check the connection first. I ended up taking it to the shop, and you were right - corroded connector. Total cost was 95€ for the repair.
