P1537
Intake Manifold Runner Control Stuck Open (Bank 1)
2009-2012 Ford Flex 3.5L V6
Low SeverityPowertrain
Description
The IMRC for Bank 1 is stuck in the open position. This affects low-RPM torque and fuel economy as the manifold runners are optimized for high-RPM airflow.
Symptoms
- Check Engine Light
- Reduced low-RPM torque
- Poor fuel economy
- Slightly rough idle
Common Causes
- Stuck IMRC actuator Bank 1
- Broken actuator rod or linkage
- Vacuum leak to actuator
- Failed IMRC solenoid
Diagnostic Steps
- Inspect IMRC actuator Bank 1
- Check linkage and actuator rods
- Test vacuum supply
- Test IMRC solenoid operation
Repair Notes
Replace IMRC actuator if stuck. Repair linkage. Fix vacuum supply.
