P2020: Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 2
What to do
Ask whether the flaps were watched moving while the actuator was commanded, before a sensor is replaced.
What this code means
The flap position signal on bank 2 is electrically valid but implausible, mirroring P2015. The same two-minute check separates the two explanations: watch the reported position while the actuator is commanded through its travel. A sensor stuck in place and flaps seized in place read identically, and only one of them is a sensor problem.

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.
