The OBD-II code P0582 refers to an issue with the cruise control vacuum control circuit. This code indicates that the system responsible for maintaining cruise control is not functioning as intended, which can hinder the operation of your vehicle’s cruise control feature.
What Does the P0582 Code Mean?
The P0582 code is triggered when the cruise control vacuum control circuit is open or malfunctioning. This means that the engine’s Powertrain Control Module (PCM) has detected a failure in the vacuum control system that regulates the cruise control operation. Essentially, the PCM expects to see a certain level of vacuum to activate the cruise control, but it is not receiving the correct signals.

Several factors can lead to the P0582 code being set, including:
- Failure of the cruise control servo
- Faulty Powertrain Control Module (PCM)
- Wiring issues within the cruise control system
