Hello users, my friend is currently on a road trip, still has about 1300 miles left and got a check engine light. The code was "Turbo Bypass Valve - p2261". If I knew enough about cars I would have told him myself, hence why I am coming here for help, or to see if anyone has gotten this code before. I looked online and found it could be his ECM, bad turbo, or build up in the turbo. Anything helps! Thanks everyone.
