Causes

Open or shorted wiring in the vacuum control circuit
Corroded, loose or damaged connector at the vacuum control valve/solenoid
Failed vacuum control valve/solenoid or vacuum switching valve (VSV)
Blown fuse or faulty relay supplying the circuit
Broken or disconnected vacuum hose or vacuum source
Faulty cruise control module or PCM (less common)

Symptoms

Cruise control inoperative or unavailable
Malfunction indicator lamp (MIL) illuminated and DTC stored
Cruise actuator does not move when cruise is engaged
Possible stored related vacuum or cruise codes
No change in engine speed when cruise set (no hold)

What to check

Retrieve freeze frame data and pending/related codes with a scan tool
Visually inspect wiring harness, connectors and vacuum hoses for damage or disconnection
Check relevant fuses and relays for continuity and operation
Backprobe the solenoid connector to verify power and ground while commanding cruise ON
Measure solenoid coil resistance and compare to spec (vehicle-specific)
Apply battery voltage briefly to solenoid (bench or backprobe) to verify actuation

Signal parameters

Control voltage when energized: near battery voltage (~11–14 V) (vehicle-dependent)
Voltage when not commanded: near 0 V or open circuit (depends on circuit design)
Typical solenoid coil resistance: low ohms to low hundreds of ohms (spec varies by vehicle)
Continuity: conductor should show continuity between PCM and solenoid; open indicates fault
Vacuum: when energized the solenoid should allow or block vacuum per design and actuator should move

Diagnostic algorithm

Connect a scan tool. Confirm P0582 and record freeze-frame and any related codes.
Perform a visual inspection of the vacuum solenoid, connector, wiring harness and vacuum hoses. Repair obvious damage.
Check fuses/relays that supply the cruise/vacuum control circuit. Replace if blown or faulty.
Backprobe the solenoid connector. With ignition ON and command active (use scan tool to command cruise vacuum if possible), verify proper supply voltage and ground signal at the connector.
Measure solenoid coil resistance with the component disconnected. An open or infinite resistance indicates a failed solenoid.
Apply battery voltage briefly to the solenoid (observe polarity if required) to confirm it actuates (you should hear/feel a click and see actuator movement or vacuum change). Use caution to avoid overheating the coil when bench-testing.
Check continuity between the solenoid connector and PCM/cruise module connector pins. Repair any open or high-resistance circuits (repair/replace damaged wiring, connectors).
Inspect vacuum lines and source. Verify vacuum reaches the actuator and that the actuator responds when the solenoid is energized.
After repairs or component replacement, clear codes, then command/system-test and road-test to confirm the fault does not return.
If wiring and component check good but code persists, consider module/PCM diagnosis or consult manufacturer-specific service information for advanced tests.

Likely causes

Damaged wire harness between PCM/cruise module and vacuum solenoid (chafing, broken conductor)
Connector pins corroded or pushed out at the solenoid
Solenoid coil open (internal break) or mechanically stuck
Fuse for cruise/vacuum control circuit blown
Vacuum hose disconnected, split, or collapsed causing no vacuum
Intermittent open due to water intrusion or connector contamination
