P2011 - INTAKE MANIFOLD RUNNER CONTROL CIRCUIT OPEN BANK 2

POST UPDATED IN February, 2023

Description of DTC code P2011 Generic

The intake manifold has internal fins, which when in operation create turbulence that produces a swirl effect. With this effect, the pulses are canceled, as the valves open and close, giving way to a better air/fuel mixture inside the engine. The position and operation of the flaps are determined by the ECM (Engine Control Module) via an Intake Manifold Runner Control (IMRC) solenoid.

If the Engine Control Module sets the P2011 OBDII diagnostic code, it is because it cannot determine the position of the flaps due to a problem in the electrical connections in the Intake Manifold Runner Control bank 2 circuit.

Symptoms of fault code P2011 Generic

  • Check Engine light illumination.
  • Trouble starting the engine.
  • Loss of engine power.

Causes of OBD2 P2011 Generic

The reasons for setting the DTC P2011 OBD2 are:

  • The IMRC Sensor internally may have an open circuit.
  • The Intake Manifold Control solenoid is possibly faulty.
  • Runner fins could be malfunctioning.
  • The Intake Manifold Control Sensor (IMRC) may have some deficiencies.

Possible solutions of the DTC code P2011 Generic

To correct the P2011 OBDII fault code you must do the following:

  • Verify that the wiring harness, connectors, and vacuum lines concerning the Intake Runner Control Circuit (IMRC) are in good condition. If wear or burns are observed on any of these components, make repairs as appropriate.
  • Inspect the intake manifold fins for carbon residue blockage. If such damage is found, proceed to make the necessary corrections.
  • Check the voltage levels of the Intake Manifold Control solenoid and the IMRC Runner Position Sensor through a DVOM. If the reading yields inconsistent data compared to that provided by the manufacturer, proceed to check its electrical connections. Repair it as required.
