Intake Manifold Runner Control Circuit Low (Bank 2)
The IMRC actuator drive line on bank 2 reads below the expected voltage threshold — typically a short to ground or a stuck-low driver inside the control module.
Affected components
- Imrc actuator
- Intake manifold runner harness
Common causes
- High likelihood: Short to ground in driver line
- Medium likelihood: Actuator winding shorted internally
- Low likelihood: Connector pins corroded - high contact resistance
