P2010: Intake Manifold Runner Control Circuit High — Bank 1
What to do
Expect a flat spot or restricted power. Ask for the actuator's winding to be measured rather than the part replaced on the code alone.
What this code means
The manifold runner control circuit on bank 1 reads above its valid range — an open circuit or a short to supply, which the module cannot separate. An open winding in the actuator and a broken wire to it read identically, and measuring the winding directly is what distinguishes a part from a harness.
Likely causes

- Open circuit in actuator wiring · moderate
- Failed manifold runner actuator · moderate
- Corroded or loose connector · easy

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.
