P0583
UniversalThe Powertrain Control Module (PCM) detects a low voltage condition in the cruise control vacuum control circuit.
Low SeverityThe Powertrain Control Module (PCM) has identified a low voltage signal within the cruise control vacuum control circuit. This condition typically results in the cruise control system becoming inoperative, which can be an inconvenience for drivers, particularly on highway journeys.
⚠️ Before You Begin (Safety First)
Always disconnect the battery before attempting any electrical repairs to prevent electrical shock and damage to vehicle components. Ensure the vehicle is parked on a level surface with the ignition off and the parking brake engaged.
Common Symptoms
- Cruise control system is inoperative
- Check Engine Light (CEL) illuminated
Common Causes
- Faulty cruise control vacuum solenoid
- Damaged or corroded wiring in the vacuum control circuit
- Poor electrical connection at the solenoid or PCM
- Vacuum leak affecting the cruise control actuator
- Faulty PCM (rare)
Frequently reported on: Ford F-150 (1997-2003), Chevrolet Silverado (1999-2006), Dodge Ram 1500 (1994-2001), Jeep Grand Cherokee (1993-2004)
Diagnostic Steps
- Connect an OBD-II scanner to confirm the P0583 code and check for any other related codes.
- Visually inspect all vacuum hoses and lines connected to the cruise control system for cracks, breaks, or disconnections. Repair or replace as needed.
- Locate the cruise control vacuum solenoid and inspect its electrical connector for corrosion, loose pins, or damage. Clean and secure the connection.
- Using a multimeter, test for proper voltage at the cruise control vacuum solenoid connector. Refer to your vehicle's service manual for expected voltage values.
- Test the resistance of the cruise control vacuum solenoid itself, comparing readings to manufacturer specifications.
- If the solenoid tests faulty or wiring issues are found, replace the defective component or repair the wiring.
- Clear the code with an OBD-II scanner and test the cruise control system for proper operation.
👨🔧 When to Call a Professional
If you have thoroughly inspected all wiring, vacuum lines, and components associated with the cruise control system and cannot identify the fault, or if you are not comfortable performing electrical diagnostics, it is advisable to seek assistance from a qualified professional mechanic.
Commonly Asked Questions
What does the P0583 code specifically mean?
The P0583 code indicates that the vehicle's computer has detected a low voltage signal within the electrical circuit that controls the cruise control vacuum system. This circuit operates the vacuum solenoid responsible for engaging and disengaging the cruise control.
Is it safe to drive my car with a P0583 code?
Yes, it is generally safe to drive your vehicle with a P0583 code. The code typically only affects the functionality of the cruise control system, meaning it will likely be inoperable, but it does not usually impact the vehicle's core driving performance or safety systems.
What are the most common causes of a P0583 code?
The most common causes include a faulty cruise control vacuum solenoid, damaged or corroded wiring or connectors in the circuit, or a vacuum leak affecting the cruise control actuator. Less commonly, a failing PCM could be the cause.
How can I diagnose the P0583 code myself?
You can start by visually inspecting all vacuum lines for cracks or disconnections, and then check the electrical connector to the cruise control vacuum solenoid for corrosion or looseness. Using a multimeter, you can test the voltage at the solenoid and the solenoid's resistance, comparing these to your vehicle's service manual specifications.
Will fixing the P0583 code be expensive?
The cost of fixing a P0583 code can vary. If it's a simple repair like a disconnected vacuum line or a corroded connector, it might be inexpensive or even free. Replacing a cruise control vacuum solenoid is typically a moderate cost for parts and labor, while more complex electrical diagnostics or a rare PCM replacement would be more expensive.
