Q: What does code P1675 mean?

EVAP Vent Solenoid Control Circuit. P1675 on GM vehicles means the powertrain control module (PCM) has detected an electrical fault in the control circuit for the evaporative emission (EVAP) vent solenoid, which is the valve that opens the system to fresh air during leak testing. The PCM monitors the circuit for expected voltage or current and sets the code when the signal falls outside the normal range, indicating an open, short, or high-resistance condition.
