P0441 on Ford: Causes, Symptoms and Fix Cost
Quick Answer
Low SeveritySafe to drive (short-term)Ford
P0441 on a Ford means the engine control unit detected that the evaporative emission system is not purging fuel vapour at the rate it commanded. The ECU opens the purge valve and expects a specific flow of stored vapour from the charcoal canister into the intake. When the measured flow is too high or too low, this code sets. The cause is almost always a purge valve that is stuck or not opening, or a vacuum line that is cracked or disconnected.

Ford Focus
2005-2024On the Ford Focus the canister purge valve (CPV) is the most common P0441 cause, especially on the 1.0 EcoBoost and 1.6 petrol engines where the valve can stick or fail to seal. Ford routes the purge line across the top of the engine, so a perished or disconnected line is also a frequent finding. A stuck-open purge valve on these engines can also cause a rough or hunting idle alongside the code.

How to diagnose P0441 on a Ford with OBD2
Follow these steps to pinpoint the root cause of P0441:
- Read the freeze frame data stored with the code. Note the engine load, coolant temperature, and fuel level at the moment P0441 set. This tells you whether the fault appears during a specific purge phase, which narrows down the valve versus a flow restriction
- Inspect the purge vacuum line from the valve to the intake manifold. Look for cracks, a disconnected or split end, or a collapsed section. A disconnected line is one of the most common causes and is quick to spot
- Perform a smoke test on the EVAP system to confirm the hoses and canister are sealed and routed correctly. This rules out a leak or blockage before you condemn the valve
- Command the purge valve open and closed with a bidirectional scan tool and watch the flow. The valve should click and pass vapour when commanded open and seal fully when commanded closed. A valve that does not open, or one that stays partly open, will set P0441
- Inspect the charcoal canister and vent valve. A saturated or restricted canister, or a vent valve that will not let air in during purge, prevents the commanded flow and produces the same code
