Intake Manifold Runner Control Circuit High (Bank 2)
The IMRC actuator drive line on bank 2 reads above the expected voltage threshold — typically a short to battery voltage or an open ground side.
Affected components
- Imrc actuator
- Intake manifold runner harness
Common causes
- High likelihood: Short to B+ in driver line
- Medium likelihood: Open ground return on actuator
- Low likelihood: Connector pins corroded - high contact resistance
