P2015: Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1
What to do
Ask whether the flaps were watched moving while the actuator was commanded — a sensor stuck in place and flaps seized in place produce the same code, and only one of them is a sensor problem.
What this code means
The flap position signal is electrically valid but implausible — most usefully, a position that does not change when the actuator is commanded to move.
That has two very different explanations and they are worth separating before anything is bought: the sensor has failed in place, or the flaps genuinely are not moving because they have seized. In the second case the sensor is reporting accurately and the fault is the carbon. Commanding the actuator through its travel while watching the reported position distinguishes them in a couple of minutes.

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.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.
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.
