What Does P2011 Mean?
DTC P2011 indicates an open circuit or general electrical fault in the intake manifold runner control (IMRC) circuit for bank 2. The ECM has detected a loss of continuity or abnormal signal behavior in the IMRC actuator circuit on the bank 2 side of the engine. This is the bank 2 equivalent of P2008 and typically results in the IMRC defaulting to a fixed runner position.
Common Causes
35%
Faulty IMRC solenoid/actuator on bank 2 (open coil)
25%
Broken or corroded wiring in the bank 2 IMRC circuit
20%
Disconnected or damaged connector at the bank 2 IMRC actuator
12%
Failed IMRC control relay or module for bank 2
8%
ECM driver circuit fault for the bank 2 IMRC output
Diagnostic Steps
1
Read freeze frame data and check for companion bank 1 IMRC codes to determine if the issue is isolated to bank 2.
2
Inspect the bank 2 IMRC actuator connector and harness for physical damage, disconnection, or corrosion.
3
Measure resistance across the bank 2 IMRC solenoid terminals; an open-line reading confirms a failed actuator.
4
Check wiring continuity from the ECM connector to the bank 2 IMRC actuator, testing both signal and ground paths.
5
Attempt bidirectional control of the bank 2 IMRC via scan tool to verify ECM driver output.
Estimated Repair Cost
$80 - $450

The most common cause of P2011 (Intake Manifold Runner Control Circuit/Open Bank 2) is: Faulty IMRC solenoid/actuator on bank 2 (open coil)
Typical repair costs for P2011 range from $80 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Minimal safety impact. Bank 2 intake runners may remain in a default position, potentially reducing mid-range power. Vehicle is safe to operate.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2011 to identify the root cause.
