P0583 OBD-II Trouble Code: Cruise Control Vacuum Control Circuit Low

Check Engine Light

P0583 code definition

A P0583 trouble code indicates that the vehicle's Powertrain Control Module (PCM) has registered an electrical malfunction in the cruise control vacuum control circuit.

What the P0583 code means

Cruise control is a feature on many modern-era models that helps the operator regulate speed while driving for long stretches. If the cruise control is found to be unable to properly maintain cruising speed, the PCM will run a diagnostic evaluation to verify whether there's a malfunction. If the tests show that the cruise control system isn't working, the vehicle computer will store the trouble code.

What causes the P0583 code?

  • A faulty component in the cruise control system
  • A cracked or broken vacuum supply hose is the most likely cause for this issue
  • A faulty cruise control servo or blown fuses
  • Broken, disconnected, faulty, corroded or disconnected wiring

What are the symptoms of the P0583 code?

A P0583 instance should disable use of the vehicle's cruise control feature. However, the P0583 code is also often reported alongside other codes, which may have wider-reaching consequences for your vehicle. For diagnostic sakes, the vehicle's onboard computer will store the trouble code in question and illuminate the dashboard's trouble lamp. This will alert the operator that there's a problem with the vehicle.

How does a mechanic diagnose the P0583 code?

  • The P0583 code may be first identified by inputting an OBD-II code reader into the vehicle's computer and scanning for reported issues.

  • Any wiring related to the cruise control system should be inspected visually for signs of fault, damage or wear.

  • The vacuum supply hose and one-way check valve should be checked for signs of damage, particularly cracks.

  • Cracks can be found by blowing a smoke machine into the hose and visually identifying leaks as such.

  • The control modules related to cruise control (including the PCM itself) should be disconnected if circuit resistance is being tested.

Common mistakes when diagnosing the P0583 code

Components related to the cruise control system are sometimes mistakenly replaced due to an undiagnosed blown fuse. Technicians also report the cruise control servo is often wrongfully blamed instead of a faulty one-way check valve.

How serious is the P0583 code?

The consequences of a P0583 trouble code should be limited to the cruise control feature. The code on its own should not otherwise hinder the vehicle's operation. However, the code often comes alongside other trouble codes which may pose other concerns for the vehicle.

What repairs can fix the P0583 code?

Additional comments for consideration regarding the P0583 code

Because testing the vehicle in drive requires someone in the driver's seat, solving a P0583 trouble code is more convenient as a two-person job.
