Description
Overview
Bosch EVAP purge valve 0280142317 (Active Carbon Purge Valve) for Citroën & Peugeot is an OEM-design solenoid valve that controls the venting of fuel tank vapours from the charcoal canister into the engine intake. It helps reduce hydrocarbon emissions and prevents fuel odours while ensuring the engine management system can purge evaporative emissions correctly.
Function And Symptoms Of Failure
The valve is pulse-driven by the engine control unit to meter canister vapours into the intake manifold. When it malfunctions you may notice fluctuating idle, difficulty restarting after refuelling, increased petrol smell around the vehicle, or an engine management light often accompanied by EVAP-related fault codes (for example P0443). Replacing a faulty purge valve restores correct EVAP operation and stabilises idle.
Causes Of Failure And Service Life
Typical causes of failure include carbon contamination from the canister, internal diaphragm or solenoid wear, and electrical connector corrosion. Service life varies depending on driving conditions, fuel quality and maintenance; there is no fixed interval, so inspect the valve if EVAP symptoms appear.
Location And Replacement Advice
On many PSA vehicles the purge valve is mounted in the engine bay between the charcoal canister and the intake manifold. Replacement is generally straightforward: disconnect the 2-pin electrical connector, release the vacuum/vent hoses, remove the old valve and fit the replacement. Observe the flow direction arrow on the valve body (arrow must point toward the intake). After fitting, clear any fault codes and perform a test drive to confirm the fault is resolved.
