Electromagnetic EVAP (evaporative emissions) vent/purge valve manufactured by DENSO. This is a used genuine DENSO unit designed to control the routed flow of petrol vapours from the activated charcoal canister back into the engine intake. Correct operation helps stabilise idle, reduce hydrocarbon emissions and prevent noticeable fuel odour around the vehicle.

Applicable Vehicles

Commonly fitted to small PSA models: Citroën C1 (I) and Peugeot 107 (I), typically for the 1.0i (1KR‑FE) petrol engine. Compatibility should always be confirmed by comparing OEM product codes on your original part.

Symptoms Of A Faulty Valve

Typical failure signs include idle fluctuations, increased fuel consumption, persistent fuel smell, illumination of the engine warning lamp and stored EVAP system fault codes (for example P0441, P0443). Failures are usually caused by mechanical sticking from deposits in the valve assembly or electrical faults in the valve coil.

Replacement And Installation Notes

The valve is located in the engine bay, usually near the intake/throttle body, and is connected with two vacuum hoses and an electrical connector. Replacement steps typically are: disconnect the vehicle battery, unplug the electrical connector, remove the vacuum hoses (replace old clamps where necessary), unfasten the retaining hardware and install the valve in the correct orientation. After fitting, clear any stored fault codes and perform a test drive to confirm the repair. Inspect hoses and connections to the charcoal canister for leaks or damage during installation.

Why Replace This Part

If you experience intermittent EVAP errors or a fuel odour, replacing the vent/purge valve is a cost-effective measure. Ensuring OEM code match and correct connector orientation guarantees proper fitment across model years and minor facelifts.
