Chrysler Sebring Trouble Code 441 Purge Problems

The computer in a car generates an error code and turns on the "Check Engine Light" when it runs a diagnostic of one of the electrical circuits in the car and finds something that is out of bounds. Error code 441 refers to the part of the cars emissions system that deals with fumes in the gas tank. It has to be dealt with before the error code can be cleared.

Error 441

All fuel tanks allow the fuel inside to evaporate slightly. Before emissions controls, the car simply dumped the fumes into the outside air, increasing pollution. Cars with emission control systems send these fumes to a canister filled with charcoal to be stored. At intervals, the emissions system opens a valve in the canister and purges the fumes by drawing them through a hose to the engine. The computer chip checks the process by pumping air out of the system to see if the canister responds. If it doesnt, it reports error 441, which means that something has interfered with this process and the canister hasnt been purged.

Possible Causes of Error 441

The error could come about because of a faulty canister or switch, a broken or damaged hose, a failure in the computer chip that controls the purge or a break in the electrical circuit controlling the process.

Cures for Error 441

Depending on the cause of error 441, the cure could be replacing the pump that tests the system, replacing the canister or hoses, repairing or replacing a component in the electrical circuit, replacing or reprogramming the cars computer chip or replacing the vacuum switch controlling the flow of fumes from the canister to the engine.
