1 vehicles · 1 makes · $250-$1,400 repair
Most Reported On
P2011 is an OBD-II diagnostic trouble code meaning “Intake Manifold Runner Control Circuit/Open (Bank 2).” This code indicates the engine computer detected an electrical problem (an open or out-of-range circuit) in the intake manifold runner control (IMRC) actuator for Bank 2, the cylinder bank that does not contain cylinder #1. The IMRC system adjusts intake airflow to optimize power and efficiency across the RPM range. An open circuit means the computer cannot properly command the runner actuator. Symptoms may include reduced power, rough running, and a check engine light, but it is generally not an immediate safety hazard. This code is most commonly reported on 2004-2014 Subaru WRX STI, with repair costs ranging from $250 to $1,400.
