Abstract

Error code P2011 indicates a problem with the intake manifold runner control (IMRC) circuit on bank 2. This system adjusts the length of intake runners to optimize engine performance. An open circuit means the control actuator is not receiving power or signal, which can reduce engine power and fuel economy.
