Description
Fuel vapor canister for Citroën and Peugeot vehicles.
The active charcoal (carbon) canister is an essential component of the EVAP (evaporative emission) system on many Citroën and Peugeot models. It captures fuel vapors from the fuel tank, stores them safely and then allows the engine to burn the collected vapors via the purge circuit. Designed for professional workshops and competent DIY mechanics, this unit with part number 1502H6 offers a direct-fit replacement option for vehicles that use the same OEM specification.
Key Benefits
- Restores proper evaporative emission control and helps eliminate fuel vapour odors.
- Direct-fit design for easy replacement on compatible Citroën and Peugeot models.
- Helps prevent fault codes related to the EVAP system and ensures correct purge operation when installed with service procedures.
Application And Compatibility
Commonly fitted to models such as Citroën C4 (including C4 II) and Peugeot 308. The part is frequently referenced by the product code 1502H6. Always verify the part number against the vehicle’s existing canister before installation.
How It Is Replaced
Replacement is straightforward for a trained mechanic or an experienced DIYer with basic tools and safe lifting equipment: raise and support the vehicle, locate the canister (typically near the fuel tank or mounted in the rear underbody/wheel arch), disconnect the purge solenoid electrical connector and all vapor and vent hoses, remove mounting fasteners, and install the new canister in reverse order. Inspect and replace any brittle hoses, clamps and the purge valve if necessary. After fitting, clear any EVAP-related fault codes and perform an OBD check to confirm correct system operation.
Installation Recommendations
- Work on a cool, well-ventilated vehicle and use appropriate lifting equipment.
- Inspect all vacuum lines, non-return valves and the purge solenoid during replacement; replace damaged components to avoid repeated failures.
- Ensure all hose connections are secure and routing matches the original layout to prevent restrictions or kinks.
- After installation, perform an EVAP system test or OBD scan to verify proper operation and to clear residual fault codes.
Why This Part Fails
- Charcoal Saturation: Over time the activated carbon can become saturated with fuel and contaminants, reducing adsorption efficiency.
- Physical Damage: Cracks or broken mounting points and damaged hose connections allow unmetered air or water ingress.
- Contamination: Fuel overfill, liquid fuel entering the canister or water intrusion can clog the unit and purge lines.
- Associated Component Failure: Faulty purge solenoid valves, clogged vent lines or failed non-return valves often cause symptoms that lead to canister replacement.

This description is intended to help professional technicians and competent DIY mechanics identify and install the correct EVAP carbon canister. Replacing the canister together with worn hoses and defective purge components offers the best chance to permanently resolve EVAP-related faults and fuel vapor odors.
