Hi guys, in need of knowledge from the various sifu here.

In the past 3-4 months my fuel consumption has increased from the normal 7L-8L/100km to 10L-11L/100km. Been to 2 mechanics and both couldn't find an issue. My car is not showing any codes either. Throttle body, maf sensor and o2 sensor have been cleaned. Spark plugs have been changed. Catalytic converter confirmed to not be clogged.

Appreciate any ideas or experiences anyone can share as I'm out of ideas beyond changing the sensors 1 by 1.

On side note, does inspira have 1 or 2 o2 sensors? I see parts for a front and rear but both mechanics say that my car only has 1.

Never change the fuel filter before. I have thought about replacing the entire fuel pump kit as i have read online that it is advisable to change every 100k. Appreciate the idea.

I've seen this error before and it was due to a wheel speed sensor that stopped communicating with the transmission control module. In your case, it could be a one time glitch which may be indicating that the part although still functioning may be starting to go bad. Found a forum post for a similar issue.
