Intake Manifold Runner Control Circuit/Open (Bank 1)

What it means

The engine computer has detected an electrical problem, usually an open circuit, in the circuit that drives the intake manifold runner flaps. The computer cannot move the flaps, so torque or power suffers depending on the position they are stuck in.

Symptoms3

• Check engine light on.
• Weak low-RPM torque or reduced high-RPM power.
• On some vehicles, no noticeable symptoms besides the light.

Possible causes5

• Loose or corroded connector at the actuator or control solenoid.
• Broken or chafed wiring between the actuator and the engine computer.
• Open internal winding in the electric actuator or vacuum control solenoid.
• Blown supply fuse or low battery voltage.
• Driver circuit fault inside the engine computer (ECU), which is rare.

How to diagnose5

1. Inspect the connector for looseness, corrosion or broken pins.
2. Confirm supply voltage at the actuator and check the fuse.
3. Measure the actuator or solenoid resistance and compare it with the manufacturer specification.
4. Check wiring continuity between the actuator and the computer, and look for shorts.
5. Command the actuator with a scan tool after the repair and confirm it responds.

How to fix5

1. Clean or repair the connector and secure it properly.
2. Replace a blown fuse after finding why it blew.
3. Repair broken or chafed wiring.
4. Replace the actuator or solenoid if its resistance is out of specification.
5. Clear the codes and confirm the flaps work and the code does not return.

The repair is often a connector or wiring fix at low cost; it rises when the actuator is built into the intake manifold and both must be replaced.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.
