P2009: Intake Manifold Runner Control Solenoid Circuit Low (Bank 1)
Standardized SAE J2012 code · P20xx — Fuel & air metering and auxiliary emission controls
What does P2009 mean?
The IMRC solenoid drive line for bank 1 reads below the lower threshold — short to ground or a failed driver stage. The runner cannot be switched on demand.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Drive line shorted to ground
- Medium Solenoid internally shorted
- Low Connector pins corroded - high contact resistance
