Description
Overview
The Bosch EVAP purge valve 0280142317 (Active Charcoal Purge Valve) is an OE-style solenoid valve that controls ventilation of the fuel tank through the charcoal canister into the engine intake. It meters purge flow under ECU command to reduce evaporative emissions and fuel odors. This unit is commonly referenced by the code 0280142317 and suits Citroën and Peugeot vehicles within the PSA family.
Function And Common Faults
The valve is operated by the engine control unit and pulses to allow controlled amounts of canister vapors into the intake. Typical failure symptoms include fluctuating idle, harder starting after refuelling, increased petrol smell and illumination of the malfunction indicator lamp with EVAP-related fault codes (for example P0443). Failures are most often caused by electrical faults, internal sticking from contamination or carbon deposits, or age-related wear of the solenoid.
Location And Replacement
On most PSA vehicles the purge valve is mounted in the engine bay between the charcoal canister and the intake manifold. Replacement is usually straightforward for a competent mechanic: disconnect the 2-pin electrical connector, remove the vacuum hoses, replace the valve and ensure the flow arrow on the valve body points toward the intake. After installation clear any EVAP fault codes and perform a test drive to confirm correct operation.
Compatibility
This Bosch valve is commonly fitted to selected Citroën and Peugeot models. Provided compatibility includes Citroën Xsara and Citroën Xsara Picasso for certain PSA engine variants. For 100% certainty always compare the part number 0280142317 and the connector/hose arrangement with your original component before fitting.
