Po440 confirmed po440 pending why would it say that


Some fault codes require multiple stop/start cycles (operating the vehicle) before it will throw a check engine light. When the code says it is pending, the ECU has detected sensor values beyond the norm. It will monitor the systems and if the problem doesn't go away (the ECU continues to see erroneous values) it will confirm the code and turn on the check engine light.

Code po440 evaporative emissions system & check engine light on


P04440 is a generic error code for the fuel vapour evaporative emission control system. This system is designed to trap fuel vapour build up in the fuel tank in a carbon canister and then to release these trapped vapours to be burnt when the engine is running. The car has a diagnostic process by which it checks the pressure integrity of the system. Anything out of the ordinary can result in the P0440 error. Check that your filler cap has a good seal and that it is fitted tightly. If this sorts out the problem the error code and CEL will disappear within a few restarts of the engine.
