Etios reduced engine power after chip tuning
Summary of the thread
A 2012 Toyota Etios experienced reduced engine power and stored an error, suspected to be a diagnostic issue. The problem was linked to faulty chip tuning, which can disrupt the engine management system. A workshop confirmed the issue, and after addressing the chip tuning, the car's performance was restored.

That's interesting. Yes, the previous owner mentioned some chip tuning. Could that be the cause?

In my case, it was. Faulty chip tuning can mess with the engine management system. I would suggest a workshop to check it. It might save you further damage.

Thank you! The workshop confirmed it was the chip tuning. The repair cost was 180€. Now everything works!

I had similar problems with my Etios. Was there any chip tuning done?
