Cruise Control Vacuum Control Circuit Low
The P0583 code indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the cruise control vacuum control circuit. This circuit controls the vacuum actuator that adjusts throttle position to maintain set speed. A low voltage signal suggests a short to ground, open circuit, or faulty component, preventing proper cruise control operation.
01. Most Common Causes
- Faulty cruise control vacuum control solenoid
- Short to ground in vacuum control circuit wiring
- Open circuit in vacuum control circuit wiring
- Corroded or damaged connector at vacuum solenoid
- Failed PCM (rare)
02. Symptoms You Will Notice
- Cruise control inoperative
- Cruise control light on dash illuminated
- Engine Check Light (MIL) on
- Cruise control disengages unexpectedly
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to confirm P0583 and check for other codes.
Step 2: Visually inspect the vacuum control solenoid and wiring for damage, corrosion, or loose connections.
Step 3: Test the vacuum control solenoid resistance with a multimeter (specs vary, typically 20-40 ohms).
Step 4: Check for voltage at the solenoid connector with ignition on; should be near battery voltage.
Step 5: If voltage is low, trace circuit for shorts or opens; repair as needed.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
Yes, the vehicle is safe to drive, but cruise control will be disabled. The issue does not affect normal driving or safety systems.
How much does it cost to fix?▼
Repair costs typically range from $50 to $150, including parts (solenoid) and labor. Diagnostic fees may apply.
