Your thinking of GM OBD-I and pre-OBD-I codes..... 2 digits:Originally posted by TruckMuddr

The GM OBD-II code format, 1996 and newer F-Bodys is 4 digits:

1441 is "flow during non-purge"..... you can get that from Rob/Shoebox's list. Means the flow detector.... the gizmo BEFORE the solenoid is detecting a flow in the purge from the EEC canister when the purge solenoid is supposed to be closed. Could be a solenoid stuck open, or it could be a faulty flow detector. Not an unusual code and often hard to analyze.Fred

It will throw a code if you have the hoses swapped.
