• P0588
• P0589
This code means that the car's computer has detected a problem with the cruise control system. Specifically, it thinks there's an issue with the part that helps control the speed of the car by venting air.
The P0587 code is triggered when the Engine Control Module (ECM) detects a low voltage condition in the cruise control vent control circuit.
The cruise control system uses various sensors and actuators to maintain a set speed. The vent control circuit is part of the actuator system that adjusts the throttle position. A low voltage in this circuit indicates a potential electrical issue, such as a poor connection or a failing component.
• Check for any blown fuses related to the cruise control system.
• Inspect the wiring and connectors for damage or corrosion.
• Test the cruise control vent control solenoid for proper operation.
• Replace any blown fuses.
• Repair or replace damaged wiring or connectors.
• Replace the cruise control vent control solenoid if faulty.
• Multimeter
• OBD-II scanner
• Basic hand tools

• Regularly inspect and maintain electrical connections.
• Avoid exposure of electrical components to moisture.
• Use quality replacement parts for repairs.
Sensor Issue
• Do not use cruise control until the issue is resolved.
• Consult a professional mechanic for accurate diagnosis.
Check with your vehicle manufacturer or dealership for specific warranty coverage related to cruise control components.
This code has been historically associated with electrical issues in the cruise control system, often due to wear and tear or environmental factors.
Moderate – While the vehicle can still be driven, the cruise control system may not function properly, which can be inconvenient on long trips.
Operating a vehicle with a malfunctioning cruise control system may lead to unexpected speed changes, which can be a safety hazard.
• Vehicle must be in a safe location to test cruise control.
• Ensure battery voltage is within normal range.
The cruise control vent control solenoid is typically located near the throttle body or within the engine bay.
Q: Can I drive my car with a P0587 code?
A: Yes, but the cruise control may not work properly, which can be inconvenient.
Q: How do I reset the check engine light after fixing the issue?
A: Use an OBD-II scanner to clear the code after repairs are completed.
