Hi Paul@ FIREFOX,
The most common cause is the engine is not upto working temp.failing this you will need to use an O.B.D 2 meter to pin point fault this will flag up a fault code it works out alot cheaper than changing parts to cure the fault hope this helps....
monitoring to detect ignition and fuel related misfires that may cause emissions to increase and/or damage to the catalytic converter.
Fuel System Monitoring to detect changes in fuel mixture that may cause emissions to increase.
Comprehensive Component Monitoring to detect any major faults in engine sensors that may cause emissions to increase.
The OBD monitors that only run under certain conditions include the EVAP monitor, HEGO monitor (Heated Exhaust Gas Oxygen sensor), and the Catalyst Efficiency monitor.
Did You Unplug The Battery Both Sides And Let Sit For #0 Minutes? Or Did You Scan With A scanner And Clear The Existing Codes? Most of The Time When You Correct The Issues With Your ECM It Will Clear Up But Just Like A computer You Must Restart It to Make Changes !! Hope This Helps !!

You can expect the check engine light to come on, on any vehicle when it gets close to 40,000 mi. The emission system has to do with the pollution control. There are several sensors that monitor your engines performance. You can still drive the vehicle, it may just not get good gas mileage or you may notice something about the engines performance. I've drove several months before actually having something done. A good garage will have a scanner and can tell you what sensor is acting up. It usually cost around $60 - $70 just to have it checked out. I had an old work van that I drove for years with the light on.
po442 is evap emission control system leak (small) 1 of the lines for emissions is leaking. po455 is-- emission control system leak (large). turn off light with code scanner after it is fixed.
