Manifold Tune Valve Solenoid Circuit
1998-2004 Dodge Intrepid 3.2L V6
Description
The PCM has detected a fault in the manifold tune valve solenoid circuit. The manifold tune valve adjusts intake manifold runner length for optimal volumetric efficiency across the RPM range.
Symptoms
- Check Engine Light
- Reduced engine performance at certain RPM ranges
- Slight loss of low-end or high-end torque
- Minor hesitation
Common Causes
- Faulty manifold tune valve solenoid
- Wiring issue to solenoid
- Solenoid connector corrosion
- Manifold tune valve stuck from carbon deposits
- Vacuum supply issue
Diagnostic Steps
- Test manifold tune valve solenoid resistance
- Actuate solenoid with scan tool and verify operation
- Inspect wiring and connector for damage or corrosion
- Check manifold tune valve for free movement
- Verify vacuum supply to actuator
Repair Notes
Replace the manifold tune valve solenoid or clean the tune valve if stuck due to carbon buildup.
