How serious is code P0441?
A P0441 engine code will display when the purge valve of your evaporative emissions system isn't functioning correctly. This disrupts the flow of vapor between your engine and fuel tank. The issue behind a P0441 doesn't pose a threat to the driver but should be fixed as soon as possible.What does engine code P0441?
Error code P0441 signals that your car's EVP system is experiencing an incorrect purge flow. (Only vehicles with a purge flow sensor or leak detection pump will display this code, so many vehicles don't list this error.)What does engine code P0443 mean?
The evaporative control (EVAP) system collects raw fuel escaping from the fuel tank. This information is then communicated to the ECM which regulates the emissions of the vehicle. The P0443 code is set when the ECM detects a malfunction within the purge control valve or a short in the purge valve circuit.What does a faulty purge valve do?
When the purge valve goes bad, it could no longer properly re-direct trapped fuel vapors from the EVAP charcoal canister into the engine. Generally, it may either circulate too much fuel into the engine or not enough of it.

Under specific conditions, often while your vehicle is parked overnight, your vehicle's on board diagnostic system (OBDII) will perform a series of EVAP system tests.What does error code P0456 mean?
What Does Code P0456 Mean? P0456 definition: Evaporative emission control system leak (small). Issue Severity: LOW – Continued driving for a short period of time is okay. Repair Urgency: Get this fixed within the next month to prevent drivability problems and excessive fuel consumption.Can a bad PCV valve cause code P0441?
When your Toyota's P0441 is triggered, it usually indicates a bad vacuum switch or a leak in the EVAP system that is preventing fuel vapors from reaching the canister. The P0441 code can also indicate a faulty or "stuck" PCV, a short circuit in the feed circuit, or a faulty purge solenoid.Will P0441 clear itself?
Usually takes about a week for it to reset on it's own, which is basically what it took for you. Always good when car problems are minor.Can I drive with a P0446 code?
