About P0582

P0582 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0582 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0582 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This fault code is triggered when the engine control module (ECM) or the body control module (BCM) detects a malfunction in the cruise control vacuum circuit. This circuit is a part of the cruise control system in vehicles where vacuum actuators are used to control the throttle position for maintaining set speeds. A malfunction in this circuit typically indicates an issue with the vacuum supply to the cruise control actuator, which can result in the inability to maintain or engage the set cruise speed.
