P0584 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The cruise control vacuum solenoid of your vehicle is controlled by the Powertrain control module. The PCM servos controls the vacuum that activates and deactivates this cruise control system. In case it is not operated as demanded by the PCM, the code P0584 will be set.

As an automobile owner, you may not understand the OBD error code and it may cause confusion. The P0548 is a standard code, which signals an electrical issue with the cruise control vacuum unit. This system mainly allows the vehicle to maintain the specific speed desired by the driver. It is controlled by the PCM which is the brain of your vehicle and cruise control module. They work together in ensuring that you face no issues pertaining to speed while driving. When they notice that that vehicle is unable to control the speed, the PCM will proceed to testing the cruise control system thoroughly, and it notices a vacuum control circuit error, it will set P0584 code.

What causes this problem with the Cruise Control Vacuum Control Circuit High?

• A defect of the vacuum supply hose that’s leading to the cruise control servo
• A defect in the one-way in line check valve leading to the cruise control servo
• Faulty electrical components in the automobile system, including wires, connectors, and fuses
• Malfunction in the cruise control switch

It is important to know about the common symptoms for this OBD error code P0584

Common Symptoms

• Inoperative cruise control
• Illuminated CEL (Check engine light)
• Specific functions inoperative as normal (e.g. set, resume, accel etc.)
• Erratic vehicle speed even after setting cruise to a particular speed
• Cruise control light permanently on in the instrument cluster
• One or more cruise control functions unable to function as normal
• Engine bay area making whistling noises

Once you know the symptoms of your vehicle’s problem, it will be easy to detect it and get started with solving it. So, next on our list is few common steps to correct this issue with your vehicle’s

• Replacing the vacuum supply hose

Here are three diagnostic steps which you can follow to diagnose this fault code:

Step 1 - Open the hood of your car and examine the cruise control system. Trace back the vacuum control line to note where it goes, and what it controls. If you observe that it’s going directly to the vacuum solenoid, thoroughly inspect the vacuum lines, cruise control servo, solenoids for any physical damage. Any visible and obvious issues can then be repaired before diagnosing. Note: While inspecting the cruise control servo, ensure you verify the cable is not seized. Monitored electrical values can totally be erratic if the cable is seized.

Step 2 - If the cruise control vacuum solenoid is present, verify the electrical values it’s displaying. This will help you eliminate the presence of any internal fault. Refer the manual provided by your vehicle manufacturer to attain precise values and procedures. You can see them mounted to the fender wells, firewall, intake manifolds etc. just ensure you are working with the right solenoid before doing anything to it. Now, if the recorded values aren’t in congruence with the manufacturers desired values, you will have to replace the solenoid completely. Next, clear the engine light and test drive your system.

Step 3 - If at any point a vacuum gauge was used, you will have to monitor the vacuum within the system. For this, you will have to ensure you acquire the vacuum from particular ports off the intake systems only. Typically, these will be present on the intake manifold itself, however, for safety it’s good to check the manual specifics. The reason for this is, that its values depend heavily on the specifics of your automobile engine. Normally, at operating temperature and with correct ignition timing the reading of vacuum should be 50-55 kPa approximately.

Common Mistakes When Diagnosing the P0584 Code

• Failure of the Cruise control servo
• A failed Powertrain Control Module (PCM)
• Issue in the wiring
