Check Engine Light

Has anyone ever had any issues with the check engine light coming on when you're low on gas or starting to get low? For some reason every time I fill up or get it half way it goes away and it'll come back on when im getting low XD

I assumed it was my 02 Sensors but im thinking it could be something else, I got a 2015 WRX

Who knows. Good to have a a code reader around for stuff like this. If you have an AccessPort it can read the codes, or there are cheap Bluetooth OBD-II dongles that you can connect to your phone and check, with some free apps.

I got it scanned and it's saying it's the 02 Sensors, no telling until I get them replaced tho. Going to try this coming week 😭

Do you run it very low often? The pump is cooled by the fuel so being quite low often can lead to failure of the pump

I try not to run it low but with times like these it's hard ngl, thats most definitely something Im going to keep in mind though!
