hi
double check the connections/plugs and clean
disconect battery for a while .
or sometimes i think it will clear after about 20 starts if all is ok

i changed the black hose from, the airbox to the throttle body, to a chrome 1. but the rubber connector came off at the throttle body and the emissions light came on. i changed back to the boring black 1 and after a few starts the light went out.

so cut a long story short, check the hose is back on properly and the sensor connector. it should go out if everyfing is ok, after a few starts

As mentioned. Try disconecting the battery for "say" half an hour. Make sure you have the radio code if your radio need one. By disconecting the battery it might "reset" the emission problem.

Does the light come on and stay on when you start up or does it just come on for about 5 seconds then go out?

If it's the latter scenario, I wouldn't worry as it's not a current fault and should disappear over time, say 30 starts.

disconnecting the battery didnt work for me. i left it an hour aswell. i just drove to and from work for the week and eventually it went out. it should correct itself. if in a few days time it hasnt gone out then id b thinkin bout gettin that sensor checked out.

Yep as mentioned above. If the fault does not occur again, then it will class it as an "historic" fault and wipe it off. I know on the Vectra B it was after 40 start up,s.
