Question about 2002 Chrysler Sebring
P0442, P0455 AND P0456 are all evaporative leak monitor test failures (small, medium and large leaks). These codes appear anytime the integrity of the air space above the fuel or the lines to/from the vapor canister or purge valve. If there is no damage to the canister, check the lines that run under the van from the fuel tank and canister to the purge valve (under the hood). Also, check to make sure that the hoses are not split or disconnected where they connect to the purge valve. The P1684 is abit more confusing. This is not a valid DTC for your vehicle. It's possible the scanner the shop you went to is an OTC scanner that is reporting a false code. It's also possible they wrote it down incorrectly. The closest thing that makes any sense is a P1486 which would indicate a pinched hose in the same monitor system as the other 3 codes. Best of luck!

Yes, the P1684 on the Chrysler line does not indicate a fault. My sebring had codes p0442 and p0456 both indicating very small evep leaks. When I did the 3 time switch on of the ignition, the odometer readout gave me the p1684 first and then the other two. The scanner at the garage only indicated two "very small evap leaks" one for the second two codes. Clearly the first is a status indicator such as recent battery disconnect or another non problematic indicator. Wouldn't it be great if these manufacturers at least gave you the information to identify what their dummy lights are telling you so you didn't have to go on faith at the garage?
