P0440 – Toyota

Fix trouble code P0440 – Toyota

Changing the air filter on a Toyota can sometimes get you a P0440 trouble code. Toyota located the EVAP solenoid vent host on the upper portion of the air cleaner housing. You have to disconnect this host to check or replace the air filter. If you’ve recently performed the check (or taken your car to a quick lube shop) and you now have a P0440 code, double check that the hose has been replaced properly. This is a common goof at quick lube shops. You take it in for an oil change. They check your air filter and forget to replace the hose. Next thing you know, you’re paying big bucks for a scan.
