Intake Manifold Runner Performance Bank 1. On the other hand, when the rpm increases, this system atomizes the fuel to increase engine performance through an effect. At higher engine rpm levels, a swirling effect is created by the imrc flaps.
Obd ii fault code p200a is a generic code that is defined as “intake manifold runner performance bank 1”, and is set when the pcm (power control module) detects that the imcr system (intake manifold runner control) system is not functioning as expected, or is functioning outside of expected parameters given the input data the pcm receives from engine and/or. At higher rpms, the intake manifold runner allows more air to flow through the intake. However, inline engines only have one bank.
