exhaust gas emissions warning light

[Liquid yellow 182]

Anything to worry about? Was driving home tonight and it came on randomly. Got someone changing my exhaust tomo so will ask him see if he knows. Just thought i'd see what you lot have to say, done a search and didn't find a very good answer. cheers

Normally due to the CAT not doing its job so could be knackered??

^ or one of the lambda sensors is fubar'd, like mine was

Pre-cat affects fueling so could be this

Post cat lmabda reads to see if the cat is working, if not it activates the emmisions lamp on dash

code reader will help you here

Hopefully i'll get some insight on whatever it is tomo. Hoping nothing needs replacing as im skint fml.

The light comes on if one of your o2 sensors is naffed.....a diagnostic machine will confirm which one and they are very easy to change.

This bloody light came up in mine last night halfway down the motorway from Belfast

It ok to drive the car until you fix this?

If i need a lambda/o2 sensor - where is the best place to source one?

Thanks

PS - the car seemed to be running as normal the rest of the way home with the light on the dash, which is the worrying part! lol

Anyone had any other problems throw this light on, apart from the lambda sensors?

This ok to drive, need the car now asap

Cheers
