Been a while but yarisworld is always a good place for this ... I got 8 year old yaris and noticing big drop on mpg, don't matter if its summer or winter I normally get over 500 km before the last bar blinks now i get the last bar to blink on slight over 400 Kim's almost 100km I'm losing in a tank... I just got Toyota to clean my injectors hoping this will get my mpg back but didn't help , tire pressure is good , I don't think I'm dragging when it comes to rear parking brake, got 5w-20 running with new air filter.... So im left with 02 sensor.

I'm not getting a cel but is it possible to check 02 sensor if it's going bad..? Thanks guys...
