What is this code P0442??
I have a 03 c5 conv,the check engine light came on but the car still runs great. The code that came up was P0442?? Is this a nuisance code or something I should be concerned about. Thanks

C6 registry reports this as:
"Evaporative Emission System Small Leak Detected ECM"
If it's a generic Chevy code, then it could be:
EVAP small leak/no flow condition
common when replacing fuel pump ( missed a connection)
or simple as broken gas cap
probable causes:
defective or loose fuel cap
EVAP canister or hose cracked-not connected
purge or vent solenoid defective
vacuum leak at engine
