P2015
Intake Manifold Runner Position Sensor/Switch Range/Performance
What it means
The IMRC position sensor on bank 1 reports a value, but it does not match the commanded flap state — for example, the flap is commanded closed yet the sensor still reads open. Common on engines where the connector pin clip wears out and the sensor reads erratic positions.
Is it safe to drive?
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
