ENG. LIGHT ON CODES PO 442 ANDPO 445 IS SHOWING UP ON SCANER
The PO 442 code is an EVAP system small leak, either in the evaporative system or cooling. Sometimes this will occur after a drenching rain and remain until the diagnosis code is reset, usually will disappear after you read the codes. If not, a dealer can reset the code system via the radio believe it or not. PO 445 is similar, an EVAP system code but is usually related to gas vapors being sent to the engine rather than through the atmospheric venting system. Check the gas cap system here first, a gas cap not properly tightened (3 click) will sometimes cause this. Also, look to the spark system wiring harness or purge control solenoid.

What about it ?
You have check light
You know it is an Evap System Issue
Same as all vehicle faults,use the codes to diagnose
the system,find the problem & resolve it
Why the problem with 02 sensor slow during catalyst monitor
Worn out Converter
Worn out O2 Sensors
Oxygen Sensors get replaced when they fail
& if they don't, you replace at 100,000 miles,
as they slow down (switching times)
They won't switch much, if their is little oxygen in
a failed converter,13 years, it's done
