P2011: Intake Manifold Runner Control Circuit/Open Bank 2
What to do
Expect a flat spot or restricted power. If both banks report circuit faults, that pairing usually has one shared cause.
What this code means
An electrical fault in the manifold runner actuator circuit on bank 2, mirroring P2008. Where circuits for both banks fault together, look at what they share — a common supply, a shared connector, or the module's output stage — rather than at two actuators failing simultaneously.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
