P0583Cruise Control Vacuum Control Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- Older engines without electronic throttle use a vacuum cruise servo on the throttle cable: a vacuum valve (closed when unpowered) opens the throttle with intake vacuum, a vent valve (open when unpowered) holds or releases it, and a dump valve fed through the brake switch vents it when braking. Where the engine module drives these valves, it checks each circuit and switches cruise off; CARB treats this as emission-neutral, usually without warning lamp. P0583 means the voltage at the vacuum valve driver is too low – a control line shorted to ground or a shorted coil, so the valve could stay powered. No manufacturer document available to us uses this code.
