P0582 - OBD Trouble Code

<<See All OBD Codes

In vehicles, the Cruise Control Vacuum Solenoid is controlled by the PCM electronically. The vacuum that activates and deactivates the cruise control system is managed by the servos control. If it doesn't operate as requested by the PCM, the error code P0582 will be stored.

This error basically means; that the cruise control system has failed a system check run by the PCM. It is usually conducted in response to vehicle speed being uncontrollable by the cruise control even though it is active. In such a situation, the computer shuts down the cruise control system all together. And then the OBD code P5082 is set.

What causes this problem with the Cruise Control Vacuum Control Circuit/Open?

• Malfunctioning vacuum solenoid
• Solenoid wiring harness open or shorted
• Loose connections near the solenoid
• Vacuum supply hose damaged (cracked or broken)
• bad one-way check valve

For us, our customers are everything, and that’s why we will help you to diagnose P0582 code by mentioning some important symptoms below:

Common Symptoms

• In operate cruise control
• Check Engine light ignited
• Cruise control light remains on or flashes

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue, you need to follow certain steps, and to solve OBD error code P0582, you will need to undergo the following replacements:

• Replace cracked or damaged vacuum line
• Replace the failed one-way check valve
• Replace the failed cruise control vacuum solenoid
• Replace any blown fuses you may find

You might also need to replace Cruise Control Switch, Body Control Module, cruise control system, Engine Control Module, fuel injection, connectors, straps and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination.

Below are three simple steps to diagnose this code:

Step 1 - Open the hood and take a look at the cruise control system. Trace back the vacuum line and note where it’s going and what it controls. If you notice that it’s going directly to a vacuum solenoid, then thoroughly inspect for physical damage of all the vacuum lines, solenoids and cruise control servos. Repair or replace any damaged parts discovered before proceeding further with diagnosis. Imp: At the time of inspecting the cruise control servos, ensure you verify the cable is not seized. A seized cable can cause electrical values to go haywire.

Step 2 - If the cruise control vacuum solenoid is found, verify its electrical values. This is done to rule out any potential of an internal fault. You can refer your vehicle’s service manual to get the exact values and procedures to do this. You can find diagrams on the firewall, fender wells, intake manifolds etc. hence, double check that you’re working with the right solenoid before proceeding to take any action. Replace the solenoid if the noted values aren’t in sync with the manufacturers, clear the engine light and test drive the system. 

Step 3 - If at all you used a vacuum gauge even once, it’s suggested to monitor the vacuum within the system. You can refer your manual on where they are located, it’s important to acquire the vacuum form specific ports off the systems. Typically, with correct ignition timing; 50-55 kPa should be the vacuum reading. Refer your vehicles manual to confirm this.

Common Mistakes When Diagnosing the P0582 Code

• Failure of Cruise control servo
• Failure of PCM (Powertrain Control Module)
• Issue with the wiring
