Title: engine management issue ?
Post by: bigpaul on 17 October 2011, 18:02:06
I own An X reg 2.6 v6 CDX

This morning driving to work one of the warning lights came on - Amber light showing an engine ?

I checked the hand book it said "fault in the engine electronics system"
It then said that the electronic system switches to an emergency running programme so that driving can be continued but not to drive like this for any length of time and to contact a deaslership.

Any ideas what this all means ? A diagnostic would cost a fortune with vauxhall how harmful is it to run like this  ? any way of resetting the indicator or is that a bad idea


Any suggestions or thoughts would be greatly appreciated its too technically out there for me

Cheers Paul

It could be anything.. being a 2.6 it's probably a commonly known code, but the only way to know how bad it is, is to check the codes.

You can do it for free yourself: http://www.omegaowners.com/forum/index.php?topic=90581.0

does it matter that the car is running like a dream as she always does would I notice these types of fault codes in the drive ?

You sure it`s a 2.6

Post by: bigpaul on 17 October 2011, 18:14:50
what an unusual question yes its a 2.6 V6 CDX on an X plate i believe it would have been one of the first face lifts made late 2000 on a 2001 spec

Do the pedal trick then, codewill probably be 0420/0430

There are a few members around Swindon,so if you cant sort it yourself, help may be at hand.One member in particular springs to mind.But it probably isnt my place to volunteer him in his absence. ;)

List of fault codes for 2.6/3.2 engines.
I think the codes Rob mentioned are for a lamda fault.There is a precat before the main cat and when thery get a bit tired they throw this fault up.The only real cure is to have the precat lamdas moved to a different location furhter along the exhaust. I was under the impression that it happened to 3.2 engines rather than 2.6, but I may be wrong.
Do the pedal trick in Aarons link (not as hard as it first appears,just needs a bit of patience and practice) and see what codes you have.Then post the codes here and more advice will be offered.

thanks hopefully someone will help im at a loss and confused why shes still running so well.

yep stupid I know
Title: Re: engine management issue ?
Post by: albitz on 17 October 2011, 18:36:51
If you can get as far as finding the code(s) Post it here and people will advise from there.Dont feel stupid by the way.We all posted questions just like yours when we first joined. ;)
Title: Re: engine management issue ?
Post by: bigpaul on 17 October 2011, 18:40:06
ok thanks for the advice I will try to read the codes (am doubtful of my competence) as has been suggested and get back with them.

In the mean time am I doing any damage running the car as it is ?

If as you say it`s the orange "engine" light and not the "spanner" light, will probably be the per-cat codes as mentioned so no damage :y

Tell us what the stored code(s) are, and we can tell you if you are doing any harm :y

It takes 2 mins to find the codes on a V6.


Yours may be a bit early for a 2.6  :-\ - PM me the reg, I can check if thats right :y

More than happy to offer any help I can ... I do have a basic code reader/resetter and a little knowledge of the V6 variants .....

Due to family commitments you only have tomorrow night (Tuesday) this week ... We're leaving for Scotland Wednesday evening to see Mrs E's poorly mum, not back until next Tuesday..

I get home about 5 ish on tuesdays so any time after that would be OK for a quick code session.

I'll PM you a phone number .. :)

Sorry, no idea where you are (update your profile ;)), hoping someone nearby can reset trims, then watch if they drift again.  Also, monitor lamda.

OK  .. been a change of plan on domestic front ..... :(

I have a meeting tomorrow night (wednesday) so will be leaving the house at 1830. That gives you a "window" of 1700 (ish) -1830 where I can reset the EML.  As we are now leaving for Scotland early Thursday morning, you can then monitor it for a week until I get back next Tuesday when we can recheck the codes and do some limited live data checking.

or just wait until next week ... obviously if someone else can help in the meantime go for it ... :)

You have the number, just give me  a ring if you intend to try and get to Wootty B tomorrow and I'll give you the address :)

I dont get home from work until usually around 18.30 so wont make it but i am off work all of next week.

Not sure my mate will be able to help with his spanners as its obviously more technical than I expected  I cant tell the difference between a spanner and a pair of socks so shows what help i am

Answered by PM ... however just to ensure the info I have given is not "wrong" I ask "those who know better" to comment on this.....  what I wrote......  :)

Quote
Fuel trim being "wrong" should not, in itself, cause any major problems if the car is not misfiring .. if its misfiring as well as then you could do some damage to engine and or cats. I could be wrong though so ask in the forum .....

My concern would always be that the light being on will "hide" any other faults... which could be more serious.

Title: Re: engine management issue ?
Post by: bigpaul on 21 October 2011, 15:00:37
so now what happens ?

The light has gone off and stayed off for the last (so far) two days.

The car was not effected performance wise with light on or off.

Curious or what ?

Ahh, right... Was on my phone :-[ :-[

Anyway. That code may stay away, may come back. Either way nothing to worry too much about. Only real solution is to move the front lambda sensors ;)

There is a theory between a couple of us that if you drive in a more spirited fashion the codes don't seem to appear, but not confirmed/guaranteed ;)

Front Lamda trim issues are usually down to fuelling, duff lamda or exhaust leaks IME.

Kevin Wood is a lamda junkie, so would be good to hear his views...

Not really any the wiser no light now for well over a week cars still driving like a dream as she always does so keep you post i guess ?
Title: Re: engine management issue ?
Post by: Kevin Wood on 29 October 2011, 09:18:45
Apologies. Back on topic. :y

Yep. Keep an eye on it. It might have been an intermittent fault, or just a ban batch of fuel. If it happens again, read the codes and see if it's still 0170 and we'll take it from there.
Title: Re: engine management issue ? - The problems returns !!!
Post by: bigpaul on 06 November 2011, 07:33:39
Hi guys

So 20 days after the light went out as Im driving home from work last night it comes back on.

Armed with my new found knowledge I have done the pedal test it appears to be showing 2 codes one after the other :-

0170     and     0173

ok thats all the information i have as usual i bow to your knowledge so please help

Strangest thing is if it all is really fuel and mixture related why is it not showing in how the car runs.  If she was coughing choking back firing and running like a pig i could understand it but nothing.  I gave her a bit of a blast on the way to work and not a thing.

help !!!!
Title: Re: engine management issue ?
Post by: bigpaul on 06 November 2011, 08:23:40
Ok guys armed with the internet which as a rule sends me here anyway i believe the codes are defined as :-

0170  -  Fuel Trim Bank 1
0173  -  Fuel Trim Bank 2

I am beginning to wonder if the sensors are the problem (Lambada)

It seem strange that the light went out for over 2 weeks without being re-set and then suddenly comes back on again ?
