Intake Manifold Runner Control Stuck Closed (Bank 1)
The intake manifold runner control valve is not functioning correctly.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine has a valve that controls how efficiently air enters it. If this valve sticks closed, the engine can’t breathe well, leading to poor performance.
What the computer is actually seeing
The engine control module (ECM) expects the intake manifold runner control to adjust and allow airflow. If it detects that the desired position and actual position of the runner are the same but it’s incorrectly set (stuck closed), it triggers a fault code.
What a healthy reading looks like
The desired position should vary between 0 to 100% depending on load and RPM. The actual position should match the desired position within 10%.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the vehicle's fluid levels and ensure there are no vacuum leaks by inspecting hoses.
- 2Visually inspect the wiring and connectors related to the intake manifold runner control for damage or corrosion.
- 3Using a scan tool, check the desired vs. actual positions of the intake runner control; they should match closely at idle and under load.
- 4If there's a discrepancy, apply voltage directly to the runner control valve to test its operation. Should respond immediately with movement.
- 5If the valve operates correctly with direct voltage but the code returns, suspect a wiring or ECM issue.
Common causes
- Stuck or faulty intake manifold runner control valve
- Vacuum leak in the intake system
- Electrical issue in the control circuit
- Miscommunication between the ECM and the valve
