Wastegate Control Solenoid Valve Low Input
2012-2016 Subaru Impreza 2.0L H4
Description
The PCM has detected a low-input signal from the wastegate control solenoid valve circuit. This solenoid regulates boost pressure on turbocharged Subaru engines by controlling the wastegate.
Symptoms
- Check Engine Light
- Overboosting condition
- Boost fluctuation
- Loss of power under boost
- Turbo system warning
Common Causes
- Faulty wastegate control solenoid
- Wiring short to ground in solenoid circuit
- Corroded solenoid connector
- Boost control system vacuum leak
- PCM driver circuit failure
Diagnostic Steps
- Test wastegate solenoid resistance
- Check solenoid wiring for shorts to ground
- Inspect solenoid connector for corrosion
- Verify boost pressure readings on scan tool
- Command solenoid with scan tool and verify operation
Repair Notes
Replace the wastegate control solenoid if faulty; repair wiring shorts in the solenoid circuit.
