Fuel Tank Pressure Control Solenoid Low
2008-2009 Subaru Legacy 3.0L H6
Description
The PCM has detected a low-signal condition in the fuel tank pressure control solenoid circuit. This solenoid is part of the EVAP system and controls fuel tank pressure during emissions testing.
Symptoms
- Check Engine Light
- EVAP system monitor incomplete
- Failed emissions test
- Possible fuel odor
Common Causes
- Faulty fuel tank pressure control solenoid
- Wiring short to ground
- Corroded solenoid connector
- EVAP system blockage
- PCM driver issue
Diagnostic Steps
- Test solenoid resistance
- Check wiring for shorts to ground
- Inspect connector for corrosion
- Command solenoid with scan tool
- Smoke test EVAP system
Repair Notes
Replace the fuel tank pressure control solenoid if it fails electrical testing.
