Hey guys, after soksta reset my check engine light i've done a few more highway drives and been driving the car daily quiet far but never used fifth gear, even at highway speeds. Today, i was sick of the 3.5krpm drone and shifted to fifth, within seconds the light had come on.

This problem only seems to occur in fifth gear, there's no mods to my my01 wrx and i've replaced the exhaust sensors. Is there anyone SoR who could scan and clear this code, and tell me what's causing it if possible?
