What it means

P0583 means the control unit has detected a low voltage or signal in the circuit that controls the vacuum-operated cruise control actuator (the vacuum control or vent solenoid). The control unit compares the commanded state of the circuit with the voltage it actually sees, and sets the code when the circuit reads lower than expected, often pointing to a short to earth or a faulty driver. This code only applies to vehicles that use a vacuum-operated cruise control system, and the layout varies by model.

Symptoms

Cruise control will not engage or cancels unexpectedly
Cruise control warning light or message displayed
Engine management light may be on
Cruise control speed not held or surges
No other noticeable change in normal driving

Possible causes

Damaged wiring to the cruise control vacuum solenoid or servo, such as chafing causing a short to earthlikely
Faulty cruise control vacuum servo or control solenoid with an internal shortlikely
Corroded, loose or damaged connector at the solenoid or servopossible
Faulty brake pedal or clutch switch circuit affecting the cruise control system, depending on modelpossible
Blown fuse or power supply fault to the cruise control circuitpossible
Fault within the control unit driver circuitrare

How to diagnose

Read all stored codes and freeze frame data, noting any other cruise control or brake switch codes
Check the relevant fuses and note the cruise control circuit layout for this specific model
Visually inspect the wiring and connectors to the vacuum servo or solenoid for chafing, melting, water ingress and corrosion
Inspect the vacuum hoses to the servo for splits, disconnection or perching against hot or sharp parts
Check the solenoid or servo coil resistance and compare with the manufacturer specification
With the connector disconnected, test the wiring for a short to earth and for continuity back to the control unit
Check the supply voltage and the control signal at the connector using the wiring diagram
Clear the code and road test to see whether it returns, confirming the fix

How to fix

Repair or replace damaged wiring and fix the cause of the chafing
Replace the faulty vacuum servo or control solenoid
Clean or replace corroded or damaged connectors and terminals
Replace any blown fuse after finding what caused it
Repair or replace faulty brake or clutch switches if they are confirmed as the cause
Replace or repair the control unit only after all wiring and components have been proven good

Can I keep driving?

Low severity

The car is safe to drive as only the cruise control is affected, though it will not work. Book it in for repair at your convenience.
