Evening all..

I am now the 'proud' owner of a 2.6 V6 Vectra B - 51 plate (Facelift?)

And after a few hundred miles the engine management light came on.... no difference in performance or misfire or anything else.

Low and behold the pin out method doesn't work as pin 6 is missing on these cars - YAY!!!!

So I disconnected the battery and it went away and came on again after about 30 odd miles and again no difference in performance or owt...

I've tried the foot on accel and brake method - doesn't seem to work to get the code to flash out. Am I doing it wrong???

So.... as I intend to keep the car for a while and I'd rather spend the £50 to get a dealer to de code it on a code machine.

Can anyone identify the one I need to buy and where from? ( Ebay ?? Halfrauds?? )
As I am a little lost.....

Thanks

Jake

OK

I have actually managed to get the foot pedal thing to work and I got

P0420 Catalyst System Efficiency Below Threshold (Bank 1)
P0430 Catalyst System Efficiency Below Threshold (Bank 2)

On the Omega forum I found this

The ECU runs a cat check cycle once the engine is up to temperature and driving conditions are right. This consists of setting a constant rich or lean mixture for a few seconds and observing how long the rich / lean indication takes to propagate from the front Lambda sensors back to the post-cat sensors. If the cat is working there will be a good delay as the cat absorbs the excess oxygen or depletes its' stored oxygen depending on the mixture.

Any ideas.....

Most importantly..... is it likely to kill my engine???

my mate has same problem he went to a garage in birmingham and just flashed it .100miles and its been fine since. normally a prob with the cat nothing major. get it looked at at a local vuaxhall place or type in google MIDPOINT GARAGE they will tell u straight away.. or regal motorsport they are the vauxhall boys and will no these things

Churtz

sounds to me like the cat is poor. if the vehicle was running super rich all the time the eml would be flashing. doesnt sound like its gonna cause problems, just not very enviromentally friendly! haha.

by the way, i work at a vaux main dealer so let me know if u need anything.

I had p0420 on my old st170, new pre-cat lamdba sensor sorted it.

To be honest I really couldn't give a fug about the cats working or not at the mo - I am just concerned that the car is running correctly - i.e. wont blow up!

The paragraph from the Omega club seems to give me some comfort...

Thanks for the offer of help Churtz/Mo for the info.

You can buy cheap or generic code readers on egay.

Or fraudulent copies of Vaux-Com or Op-Com.

I think Gendan does legit stuff at decent prices though ?

Shings

Linky?? I'd like to get a generic one not just a vauxhall reader.

Doesn't need to be owt special.

The 2.6 has 3 cat convertors and hates low RON fuel for some reason.

Put some Super unleaded in and take it for a blast.

www.vvoc.com is useful.

Shings

Super Unleaded - pah - not unless its got a Turbo its tooooo damn expensive.


I do want to join - but I hate people who join a forum and first post is.

MY X Y Z is broken can you help?

and then never post again....

stevieturbo

Link for what ?

it isnt hard to google or search ebay for Vauxhall code readers ? or gendan

And I'm not linking to the Op-Com or Vaux-Com copies....because they are illegal copies

Here is the original legal version though
