Q: What does code P1561 mean?

Cruise Vent Solenoid. P1561 on GM vehicles means the powertrain control module (PCM) has detected an electrical fault in the cruise control vent solenoid circuit. The vent solenoid is the valve that releases vacuum to disengage the cruise servo, so the PCM monitors its circuit for opens, shorts, or excessive current draw and sets this code when the signal is outside the expected range.
