P0441, P0443 and related: EVAP purge valve
The valve that lets fuel vapour from the charcoal canister into the engine is not flowing as commanded, or its electrical circuit is open, shorted, low or high.
SeverityLowLittle risk to the car, but the fault stays until it is repaired.
Can you keep driving?Safe to drive, book a checkWhat does P0441 mean?
The purge valve opens at chosen moments to draw stored fuel vapour from the canister into the intake, where it is burnt. The computer checks it by watching the mixture or the system pressure change when it opens the valve. If nothing changes, or too much does, it stores a flow code; if the coil's circuit is wrong, a circuit code.
What causes P0441?
- A purge valve that sticks open or closed
- A cracked or disconnected purge hose
- A broken wire or corroded connector at the valve
- A blocked canister or canister vent
What to check first for P0441
- Check the purge hoses between the canister, the valve and the intake for cracks
- Listen for the valve clicking when the engine is warm and the scan tool commands it
- Inspect the valve's connector and measure the coil's resistance
- Notice whether the engine is hard to start just after refuelling, a sign of a valve stuck open
Can you drive with P0441?
Safe to drive. A valve stuck open can make the engine hard to start after refuelling and run rough at idle for a moment; otherwise you will notice little.
Since May 2018 an engine warning light that stays on is a major defect at the MOT, so the car fails until the fault is fixed.

These are the generic meanings every manufacturer shares. Each brand adds its own detail, so your car's handbook, its service information and a qualified mechanic have the last word. OdoKeep has no connection with any manufacturer, and the app does not read codes from the car.
