Getting P0441 engine code on 1999 Corolla

From: BillyG on 9 Aug 2008 14:39 My 1999 Corolla with about 40,000 miles on it over the past month has been registering P0441 that represents "EVAP Emission control system purge flow fault." Less than two months ago I had to replace the starter on this car because of solenoid failure and read that EVAP solenoid failures are listed reported as the worst problem with this car. I further read that most of the time the charcoal canister located near the gas tank has to be replaced if the car is taken to a dealer for repair. Anyone have experience with this? The car rarely gets out on the highway so someone suggested a long highway trip might solve the problem if it was just a matter of clogging. All ideas welcomed.

Try tightening the gas cap a minimum of 6 click. It should solve the problem in one or two starts. If not, the next cheapest thing is to find a new cap; if you have vehicle inspections where they check the gas caps for leaks, take it to one of those first. If this doesn't resolve the issue it's time to delve deeper...

You can try a drive on a highway of a half hour or more, but I doubt if it would fix the problem. Tightening the gas cap will not fix the problem either. Basically, the charcoal canister absorbs and stores the evaporative emissions from the fuel tank, and when the car is started, the canister is purged and the engine burns the fumes that come out of the canister when it is purged. If the charcoal canister is not purged properly like when a solenoid actuated valve is not functioning, the charcoal canister may become saturated and lose its ability to absorb the vapors from the fuel tank. I think you can start by having the purge valve replaced and see if that solves the problem. -- Ray O (correct punctuation to reply)

The canister will have a couple of thin hoses on top and one on the bottom. Follow the hose that goes from the charcoal canister to the throttle body; the purge valve shoud be along that hose somewhere if it is not built into the canister. You can get a diagram at autozone.com. Look up the repair guide for your car, then look for emissions, then look for evaporative emissions for the 7A-FE engine. -- Ray O (correct punctuation to reply) |
