Decoding what the CEL actually is telling you.. Most common subaru CEL codes causes and fixes.
The Check Engine Light hurts in the stomach when it comes on, so I go through the most common CEL codes I come across with what the causes and fixes are including some red herrings along the way.. I hope it makes it easy to solve for you.
Fire in your CEL codes in the comments and I will try and answer them, point you to fixes.. If you do please let me know the year and model 👍

So glad I found this channel.
Very useful information, can’t wait for more post.
hi, sorry i couldn't make the live but i am catching up here and now. firstly thank you for sharing this info and more importantly for helping me out the other week with my po301 fault. the gearbox switch was faulty. i am booked in next month for a map with you after jumping into spending some cash on my 03 blob wrx. i have fitted all my upgrade bits (vf35, 550cc injectors, tgv deletes, 255 fuel pump, sti intercooler, up-pipe and now a sports cat. had it running last night and took for a gentle drive tonight to make sure everything is ok. i have a load of tgv faults which i expected as everything is unplugged. however, i also have a P0420 cat system efficiency. for a point of good measure, i fitted new denso O2 sensors when putting it all back together so i don't believe that is an issue. could this be my sports cat isn't efficient? or that this needs to be altered when you map next month? car isn't going to be used anymore till i come down to you next month as its clearly over fuelling a fair bit with the injectors in so don't want to cause any damage.
