This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the system that adds special liquid to the fuel to help it burn cleaner, and it's asking for the warning light on the dashboard to turn on.
The Fuel Additive Control Module (FACM) monitors the level and operation of the fuel additive system. When it detects a fault, it requests the engine control module to illuminate the warning lamp.
The P2585 code is triggered when the Fuel Additive Control Module detects an issue with the fuel additive system, such as low additive levels or a malfunction in the system, and requests the Engine Control Module (ECM) to turn on the warning lamp on the dashboard.
• Check engine light is on
• Warning lamp specific to fuel additive system is illuminated
• Possible decrease in engine performance
• Low fuel additive level
• Faulty fuel additive control module
• Wiring issues or poor connections
Fuel Additive: A chemical added to fuel to improve combustion and reduce emissions.
FACM: Fuel Additive Control Module, a component that manages the fuel additive system.
• Check the fuel additive level and refill if necessary
• Inspect the wiring and connections to the fuel additive control module
• Use a diagnostic scanner to check for additional codes
• Refill the fuel additive tank
• Repair or replace faulty wiring or connections
• Replace the fuel additive control module if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

• Peugeot 307
• Citroën C4
• Ford Focus
• Regularly check and maintain fuel additive levels
• Perform routine inspections of the fuel additive system
• Ensure proper connections and wiring integrity
Fuel System Issue
• Do not ignore the warning light; address the issue promptly
• Consult a professional mechanic if unsure about the repairs
Check your vehicle's warranty for coverage on emissions-related components.
This code has been more common in vehicles equipped with diesel engines and particulate filters that require fuel additives.
Moderate – This issue should be addressed soon to prevent engine performance issues and maintain emissions compliance.
Ignoring this code can lead to increased emissions and potential legal issues with emissions compliance.
• Engine running
• Fuel additive system active
The Fuel Additive Control Module is typically located near the fuel tank or within the engine compartment.
Q: What does the fuel additive do?
A: The fuel additive helps reduce emissions by improving the combustion process and cleaning the exhaust system.
Q: Can I drive with a P2585 code?
A: While you can drive with this code, it's advisable to address it soon to avoid potential engine performance issues.
