SPCUT Solenoid Circuit Malfunction

Where it lives

For P1494, the description names the solenoid as the part involved.

Check these first

• A leak detection pump that has failed
• An open or short in the leak detection pump harness
• A poor electrical connection at the leak detection pump
• A leak detection pump that will not seal the vent valve

What to do next

1. Command the leak detection pump with a scan tool
2. Listen for the pump running during the EVAP self test
3. Inspect the leak detection pump connector and wiring
4. Test the leak detection pump circuit for open and short faults
5. Replace the leak detection pump if it will not run or seal
6. Clear the code and retest
