Intake Manifold Short Runner Solenoid Circuit
1998-2004 Dodge Intrepid 3.2L V6
Description
The PCM has detected a malfunction in the intake manifold short runner solenoid valve circuit. This solenoid controls the short runner valve position to optimize airflow at different engine speeds for improved torque and efficiency.
Symptoms
- Check Engine Light
- Reduced mid-range torque
- Slight hesitation on acceleration
- Minor fuel economy decrease
Common Causes
- Faulty short runner solenoid valve
- Wiring open or short to solenoid
- Corroded solenoid connector
- Carbon buildup on runner valve preventing movement
- Vacuum leak at solenoid actuator
Diagnostic Steps
- Test solenoid resistance with multimeter
- Command solenoid on and off with scan tool and listen for click
- Inspect solenoid wiring and connector
- Check vacuum supply to runner valve actuator
- Inspect runner valve for carbon buildup or binding
Repair Notes
Replace the short runner solenoid valve if electrically faulty; clean carbon from runner valve if mechanically stuck.
