P0582
Cruise Control Vacuum Control Circuit/Open
Cruise control
Generic OBD-II
Low
What it means
P0582 means the ECM detected an open (broken) circuit in the vacuum control that operates a vacuum-actuated cruise control system. With the circuit open, the system can't build or hold the vacuum it needs, so cruise control stops working. The engine drives normally — only cruise is affected.
Low
Can I keep driving? Safe to drive — only cruise control is affected. The engine runs and drives normally; you'll just lose the ability to set or hold cruise.

How to diagnose & fix
Work through it in order
- Read freeze-frame data, then locate the cruise control vacuum actuator/solenoid and inspect its connector for damage or corrosion.
- Check the vacuum supply hose and one-way check valve for cracks, leaks, or blockage.
- Test the solenoid's control circuit for continuity/an open against the ECM.
- Replace the vacuum solenoid, hose, or check valve as the fault dictates.
- Clear the code and confirm cruise control operates.
