P2015 2010 Ford Fusion Code - Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1

P2015 indicates an issue with the intake manifold runner position sensor or switch on Bank 1, specifically that its range or performance is outside the expected parameters.

Symptoms may include a check engine light, reduced engine performance, poor fuel economy, rough idling, and hesitation during acceleration.

Common causes include a faulty intake manifold runner position sensor, carbon buildup in the intake manifold, a malfunctioning intake manifold runner control motor, or damaged wiring or connectors.

While the car may still be drivable, it’s not recommended to ignore this code as it can lead to reduced performance, increased emissions, and potential engine damage if left unresolved.

Diagnosis involves using a scan tool to confirm the code, inspecting the intake manifold runner system for damage or carbon buildup, and testing the position sensor, control motor, and associated wiring.

The intake manifold runner position sensor monitors the position of the intake manifold runner valves, which adjust airflow for optimal engine performance.

Repairs may include cleaning or replacing the intake manifold runner, replacing the position sensor, fixing damaged wiring or connectors, or replacing the intake manifold if it’s severely worn.

You’ll typically need a scan tool, multimeter, basic hand tools, and potentially a throttle body or manifold cleaning kit if carbon buildup is the issue.

Repair costs can range from $100 to $1,000 depending on whether cleaning, part replacement, or a full intake manifold replacement is required.

Yes, excessive carbon buildup in the throttle body or intake manifold can obstruct the movement of the runner valves and trigger a P2015 code.
