Re: P1441
Accessing the code stored by the CPU is the first step of diagnosis. Additional description of code P1441 is, Evaporative emission control system very small leak, positive pressure. The problem may be that the purge control valve which is part of the charcoal canister has a slight leak. If the control valve doesn't completely close, there will be flow during non-purge. Vacuum drawn through the small hose to the charcoal canister is what opens the purge control valve. Make sure that there is no vacuum to the smallest hose connected to the canister at idle. Make sure the little hose is not kinked or pinched in some way that would hold vacuum to the purge control valve. The canister is purged above 35 MPH, never at idle. Have you tried erasing the code to see if it returns? Is P1441 the only code stored? The canister appears to be a dealer only item. My guess would be that diagnosis, canister replacement, and reset the CPU costs close to $200 for parts and labor.
