I dunno... I'm not going to pretend like I know all the computer inputs on a turbo WRX, that CEL could be a lot of different things. Oxygen sensor, intake air temp sensor, water temp sensor, boost pressure, etc. etc. etc... that car has sensors everywhere and I assume all of them could throw a CEL when out of spec. Check it out with a code reader? Or someone else who knows more about it *cough*Scott*cough* could chime in...
