Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Subaru WRX STI · 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.
Common Symptoms
- Check Engine Light with TGV-related codes
- Rough idle or stumbling on cold start
- Reduced throttle response
- Poor fuel economy
- Intermittent hesitation at low RPM
How to Fix
Scan for TGV-related codes and verify actuator movement and sensor feedback; repair wiring/connectors as needed. Replace the affected TGV assembly or sensor/motor components and perform ECU relearn procedures per Subaru service manual; ensure no intake vacuum leaks after reassembly.

Frequently asked questions
What does P2011 mean?
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.
What are the most common causes of P2011?
The most common causes of P2011 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P2011?
Repair costs for P2011 range from $250 to $1,400, depending on the vehicle and root cause.
