If you have a 2009-2011 Toyota Corolla with a customer complaint of lack of power and/or check engine light on with codes P060E, P0504, P0575, C1425, C2173 then check the rear brake lights (Dual Filament). What we are seeing is that one on the bulbs filaments will break and touch over to the other circuit and back feed into the ECM. The fix is to replace the brake light bulb.
