P2011 on Subaru
Intake Manifold Runner Control Circuit/Open (Bank 2)
P2011 on Subaru vehicles indicates intake manifold runner control circuit/open (bank 2). Au7o has documented this code across 1 Subaru model — most commonly on WRX STI. 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. Typical repair costs on Subaru range from $250 to $1,400, depending on the specific model and root cause.
Common Causes of P2011
- •Open or broken wiring in the IMRC actuator circuit
- •Corroded or loose electrical connector at the actuator
- •Failed IMRC actuator or solenoid on Bank 2
- •Carbon buildup binding the runner mechanism
- •Faulty intake manifold runner position sensor
- •Damaged PCM driver circuit (rare)
P2011 on Subaru by Model
Subaru WRX STI(1 issue)
- Tumble Generator Valve (TGV) Sensor/Motor Fault (P2004/P2005/P2011/P2016)2004-2014
WRX STI models with EJ257 intake TGV assemblies can develop failures in the TGV position sensors or actuator mechanisms, leading to stuck-open/stuck-closed conditions. Owners report check engine lights, rough cold starts, and reduced drivability, especially in colder weather. This issue is frequently discussed in owner reports and appears in diagnostic guidance/TSBs for Subaru intake runner control/TGV-related DTCs.

What does P2011 mean on Subaru?▼
P2011 stands for "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. On Subaru specifically, this code is documented across 1 model.
What causes P2011 on Subaru vehicles?▼
Common causes on Subaru: Open or broken wiring in the IMRC actuator circuit, Corroded or loose electrical connector at the actuator, Failed IMRC actuator or solenoid on Bank 2, Carbon buildup binding the runner mechanism, Faulty intake manifold runner position sensor. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2011 on a Subaru?▼
Repair costs on Subaru range from $250 to $1,400, depending on the specific model and root cause.
