P2008Fuel & Air Metering

Intake Manifold Runner Control Circuit Open Bank 1

P2008 means the ECM detected an open circuit in the intake manifold runner control for Bank 1. This is an electrical fault in the actuator or solenoid control circuit rather than a mechanical jam. Wiring, connectors, or a failed actuator are the usual causes.

🚗 Yes, but performance may be uneven and the code should be addressed soon.

MEDIUM

severity

🎯 Top Causes, Ranked by Likelihood

#1Open or damaged wiring in the control circuit$50-$250

35%

A broken wire or corroded connector interrupts the actuator control.

#2Failed IMRC actuator or solenoid$100-$400

35%

The actuator coil has an internal open and no longer responds.

#3Poor ground or power supply to the circuit$50-$200

20%

A bad ground or blown fuse can open the circuit.

#4ECM driver fault$200-$1000

10%

Rare, but a failed control driver in the ECM can cause this.
