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.

Function

The canister is part of the EVAP (Evaporative Emission Control) system. It traps fuel vapors in activated charcoal and, when commanded by the engine control system, releases those vapors through the purge solenoid into the intake manifold to be burned in the engine. Proper canister function prevents raw fuel vapor from being vented to atmosphere and avoids drivability problems caused by uncontrolled vapor flow.

Replacement Procedure (Overview)

• Locate The Canister: Depending on model and year, the canister is mounted either in the engine bay area or under the vehicle near the fuel tank.
• Prepare The Vehicle: Work on a cooled vehicle, park on a level surface and support safely if lifting is required. Wear appropriate PPE.
• Disconnect Components: Carefully disconnect electrical connectors and vacuum/fuel vapor hoses. Label hoses to ensure correct reconnection.
• Remove Mounting Hardware: Unbolt the canister from its brackets and remove it. Note that the three white brackets (1502E5) mentioned are not supplied with this unit.
• Install New Canister: Fit the canister, secure mounting bolts, reconnect hoses and connectors using new seals or clips if necessary.
• Finalize: Clear EVAP fault codes with a diagnostic scanner, perform a purge/pressure test and confirm no leaks and correct purge operation.

Installation Recommendations

• Replace brittle or cracked vacuum hoses and worn clips when changing the canister to prevent future leaks.
• Use an OBD-II scanner to clear codes and run an EVAP system test after installation.
• Avoid overfilling the fuel tank—this is a common cause of premature charcoal saturation.
• Handle hoses and connectors gently; replace any damaged seals or clamps. Keep the work area free of open flames and sparks.

Most Common Causes Of Failure

Canister failures are typically caused by charcoal saturation due to fuel contamination or overfilling, physical damage or cracking from heat and age, and blocked or failing purge solenoids and hoses. Faulty purge valves or damaged vapor lines often produce EVAP fault codes (P0441, P0443, P0446) that can be misattributed to the canister unless the entire EVAP circuit is inspected.

Ideal For professional mechanics and knowledgeable DIY customers who search by part number (1502H6) and need a direct replacement for affected Citroën and Peugeot models. Ensure correct fitment by comparing part numbers and visual mounting points prior to installation.
