P0586 - OBD Trouble Code

<<See All OBD Codes

In your vehicle, there’s the Cruise Control system, it uses vacuum to sustain speed. This happens when the cruise Control Vent Solenoid allows your car system to release vacuum, if the vehicle has to slow down. When the Vent Control Solenoid isn’t performing as requested, error code P0586 will be set, this will disable the cruise control system.

This is one of the basic and frequently found OBD-II codes. The Cruise Control Module and the PCM control the cruise control system. They both work cohesively to ensure the vehicle speed is controlled automatically as needed. In the case when the speed can’t be controlled, the PCM will test the entire cruise control system. Once tests are conducted by the PCM and it is noted that there were irregular voltage and resistance signals sent from the cruise control vent, then the P0586 code will be detectable.

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

• Electrical components in the Cruise Control System are damaged
• Incompetent cruise control switch, which also results in a liquid spill in the interior of the vehicle

Here are some steps which you should follow in order to diagnose this fault code:

Step 1 - Pop open the hood of your vehicle and start off by visually observing your cruise control system. Trace the vacuum control line and see where it goes and what exactly is it controlling, if it’s going directly to the vacuum solenoid, you will have to inspect the vacuum line, solenoids cruise control servo properly. If there are any physical damages that you are able to fine then try to repair or replace as per need, before proceeding further with diagnosis. At the cruise control servo, double check to verify that the cable isn’t seized. A seized cable can have the electrical wires go haywire.

Step 2 - Now by using your manual, rule out any possibility for internal faults in the cruise control vacuum solenoid. In-order to do this, you’ll have to match them with the electrical values given by your manufacturer for your specific vehicle and its model. These precise values and procedures can mostly be found stuck on the firewall, fender wells, intake manifolds etc. This will facilitate in concluding that you’re working with the right solenoid before proceeding to doing anything. Now move ahead and replace the solenoid, clear the engine light and go on a test-drive. If the values are outside the ones your manufacturer has stated.

Step 3 - If in case you have used a vacuum gauge even once, monitor the vacuum within the system. This is important that you acquire it from specific vacuum posts off the intake systems of your vehicle. You can find these on the intake manifold. For clarity, you can always refer the manual. Generally, at operating temperature with the right ignition timing, most vehicles will show vacuum reading between 50-55 kPa. But this may vary from engine to engine, so to be safe, refer the specifics on your specific vehicle’s manual.

Common Mistakes When Diagnosing the P0586 Code

• Unnoticed failure of the Cruise control
• Unexpected failure of the Powertrain Control Module (PCM)
• Issue with the wiring of the system
