Chosen Solution
I have a Toyota Corolla 2009 Engine: 1.8L. I have not tried anything yet, where do I start?
@johnnickerson okay that’s a wild one. C1511 - Left Front Wheel Pressure Reduction Performance Problem. Lets see what we can find out about that code. Sounds like an issue with the torque board on the power steering.
try fixing error code c1511 first.
