P0582 OBD-II Trouble Code: Cruise Control Vacuum Control Circuit/Open

P0582 code definition

The P0582 code indicates that there has been a malfunction detected in the cruise control vacuum control circuit by the car’s computer.

What the P0582 code means

The P0582 code means that the cruise control system has failed a system check conducted by the PCM. This test is usually conducted in response to uncontrolled vehicle speed while cruise control is active, in which case the computer shuts the cruise control system down and sets a diagnostic code.

What causes the P0582 code?

There are only a few potential causes for the P0582 code, and they include the following:

  • Faulty vacuum solenoid
  • Open or short in solenoid wiring harness
  • Loose connection at the solenoid
  • Cracked or broken vacuum supply hose
  • Faulty one-way check valve

What are the symptoms of the P0582 code?

Symptoms of the P0582 code can include the following:

  • Cruise control inoperable
  • Check Engine light on
  • Cruise Control light stays on or flashes

How does a mechanic diagnose the P0582 code?

Diagnosing the P0582 code starts by connecting an OBD II scanner to the car’s computer connection. Once connected, the mechanic can read all the codes stored in the system. The mechanic will also perform a complete visual inspection of all wires and connections, as well as vacuum lines. After the inspection, the code should be cleared and the vehicle test driven with an attempt to activate cruise control.

If all hoses appeared normal, the mechanic should perform a vacuum pressure test. He or she should also check the operation of the one-way valve, as well as the cruise control switch. The mechanic should also check for blown fuses both before replacing any components and afterward. A blown fuse can indicate further electrical problems, as well.

The problem may actually lie with the cruise control module itself. The mechanic should test this to ensure that it reads within manufacturer specifications. If it does not, it will need to be replaced.

There is also a possibility that the problem lies with the switches for the cruise control system. Depending on the make and model in question, those may be on the cruise stalk, or located at various points on the steering wheel.

Common mistakes when diagnosing the P0582 code

The most common mistake here is replacing the cruise control vacuum solenoid when the actual problem is the one-way check valve. A full diagnostic will ensure that all components are inspected and the true underlying problem is found. Blown fuses are often a hidden cause here as well, although they generally highlight another, deeper problem.

How serious is the P0582 code?

The P0582 code will not keep you from driving the car, nor will it adversely affect driving or performance. It will only prevent you from using cruise control. However, this can be a significant inconvenience, particularly during longer drives when fatigue can become a problem. Have it diagnosed and repaired soon.

What repairs can fix the P0582 code?

A number of repairs can fix the P0582 code, depending on the actual underlying cause. These can include:

  • Replacing a cracked or damaged vacuum line
  • Replacing a failed one-way check valve
  • Replacing a failed cruise control vacuum solenoid
  • Replacing blown fuses

Additional comments for consideration regarding the P0582 code

Diagnosing problems with the cruise control system can require a significant investment of time, and a considerable amount of electrical testing to determine which components are the culprit. Never assume that the P0582 code is relegated only to vacuum failures.
