Product Overview

Active carbon/charcoal canister designed to capture and store fuel vapours from the fuel tank and EVAP system on selected Citroën and Peugeot models. This component prevents hydrocarbon emissions from escaping to atmosphere and works together with the purge valve and EVAP hoses to route stored vapours back to the engine for combustion. Frequently searched under part numbers 1502H9 and 9683409180.

Why This Part Matters

The charcoal canister is a passive but essential part of the evaporative emissions control system (EVAP). A healthy canister keeps fuel vapours contained, reduces unpleasant fuel odours, and prevents EVAP system fault codes (for example P0440, P0441, P0442, P0443, P0446) and related drivability issues. Replacing a failed canister restores correct EVAP function and helps the vehicle pass emissions inspections.

Fitment And Common Applications

Common applications include Citroën C4 and Peugeot 307 models. Many technicians and DIYers locate compatible parts by product code (1502H9, 9683409180). Always confirm fitment by matching the part number and physical mounting location on the vehicle.

Signs Of Failure

• Illuminated Check Engine Light With EVAP Codes (e.g. P0440, P0441, P0442).
• Strong Fuel Smell Around The Vehicle Or In The Cabin.
• Poor Idling Or Minor Hesitation When The Purge System Malfunctions.
• Visible Damage To The Canister Body, Broken Hoses Or Connectors.

Typical Causes Of Failure

The most common reasons the canister fails are saturation or contamination of the activated carbon (for example by liquid fuel entering the canister), physical damage from underbody impact, degraded or cracked EVAP hoses and seals, and clogging caused by debris or water ingress. In many cases the canister itself remains functional but associated components—piping, valves and seals—fail first and lead to increased loads or contamination of the canister.

Replacement And Installation

Replacement is straightforward for a competent mechanic with basic workshop tools. Typical steps:

• Locate The Canister (Usually Mounted Near The Fuel Tank Or Rear Underbody Depending On Model).
• Relieve Fuel System Vapour Pressure By Parking The Vehicle In A Ventilated Area; Avoid Open Flames.
• Remove Any Protective Panels Or Shields Securing Access To The Canister.
• Disconnect EVAP Hoses And Any Electrical Connectors (Note Position And Routing For Reassembly).
• Unbolt The Canister Bracket And Remove The Unit.
• Install The New Canister Using New Clamps Or Gaskets Where Applicable; Reconnect Hoses And Connectors In Their Original Positions.
• Perform A Leak Check And Clear EVAP-Related Diagnostic Codes With A Scanner After Replacement.

Recommended Checks During Installation: Inspect Purge Valve Operation, Replace Any Brittle Or Cracked Hoses, Verify Clamps And Mounting Brackets Are Secure.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C4; Peugeot 307
• Product Codes: 1502H9; 9683409180

Installation Recommendations

• Use OEM-Equivalent Hoses And Clamps To Ensure Proper Sealing And Long Service Life.
• Replace Any Associated Rubber Lines If They Show Signs Of Age Or Damage.
• After Installation, Clear Fault Codes And Carry Out An EVAP System Test Or Smoke Test To Confirm No Leaks.
• Keep The Canister Dry During Fitting; Avoid Allowing Liquid Fuel Into The Unit.

Why The Part Most Commonly Breaks

Most failures are caused by fuel contamination (liquid fuel entering and saturating the carbon), physical damage from impacts, or progressive deterioration of connected hoses and seals that allow moisture and debris to enter the canister. Preventive checks of hoses and purge components during routine servicing significantly reduce premature canister failures.

Original fuel vapor tank with active carbon for dogs PSA. This episode (EVAP Charcoal Canister) captures petrol fumes from the fuel tank and burns them via the ventilation valve. It helps reduce emissions, prevent fuel odor around the car and stabilize the pressure in the tank. Suitable solution for service repairs and home workshop, especially where the priority is a match with the original construction.

Typical manifestations of defects are the odor of gasoline around the car or in the garage, difficult refueling (blasting of the gun), hissing when opening the lid of the tank or EVAP error codes (eg P0441, P0443, P0446). Damage occurs most often due to age and soaked moisture, mechanical cracking of the body of the tank or frequent “refilling after click” when refueling, when active coal easily overlap.

The replacement is usually straightforward: the tank is located near the fuel tank, usually at the rear axle. It is necessary to lift the vehicle safely, release the bracket, disconnect quick couplings and vacuum/ventilation hose and replace the piece by piece. It is recommended to check the condition of the hoses, the seal and the valve function at the same time. After assembly, fry any error codes and check the EVAP tightness tightness. The part is designed for petrol versions where the tank ventilation system with activated carbon is used.

It is an original part of a PSA with product number 1502H6, which is kept as NFP (finished production). It is all the more important to verify the conformity by the part number – the compatibility is best confirmed by comparison with the original components or via VIN.

technical information

• Manufacturer: PSA (Citroën/Peugeot)
• Model: Citroën C4 II; Peugeot 308
• product codes: 1502H6; 1502.H6
• additional numbers: 1502 h6; NFP (discontinued production in a dog)

For trouble -free installation, pay attention to the correct hoses and the locking clips. After replacement, avoid turning the tank that shortens the life of activated carbon. If you are unsure of compatibility, compare the part number 1: 1 with the one on your original magazine, or use VIN verification.
