Title: P0420/430 codes
Post by: diamondhammer on 17 July 2016, 20:57:04
I've just purchased a very nice Omega Elite 3.2 V6 53 plate for only £300..Having driven it for a few days the engine light has come on and the codes above have been detected. I know the previous owner, and the car has been well looked after, but has sat around for the last 6 months due to his illness, thus selling it on to me. My question is..I;ve seen many threads on this common problem all suggesting at some point to move the sensors..could someone explain how and what is required to to this..also the codes were read by the foot pedal method as i could't find the OBD2 socket, any ideas where it's located.. >:(

Under the steering column is a fuse box. To the left of the fuses is the OBD2 socket.

OBD2 socket is in the fuse flap under the steering column, you'll see it amongst the relays. P0420/0430 is apparently quite common, although I've never suffered from it myself. I'm led to believe it's a driving style thing.  ;)
The moving of the sensor involves welding a new threaded boss in to the pre-cat section, moving the post-cat sensor to the new position and plugging the old hole. This fools the sensor and avoids the light coming on. If I've got this arse about face I'm sure someone will soon correct me but that's the principle of it. The other alternative is to drive fast everywhere.  ::)

Thanks for the reply. I was starting to think it's a driving thing..i had tended to put my foot down a little and I know the previous owner drove at a snails pace lol..
