EML light on

[bob.dent]

Driving to work this morning the EML came on, but car seems to be running fine. I know I need to get the fault codes read but I don't know anyone near me that has a Tech2. My local garage that services the car has a diagnostic computer but don't know if that will read sufficient information.

A couple of questions. Is there any reason not to carry on driving with the EML on and is it possible this might be caused by dodgy sensors which I know the Omega can be prone to?

Well, if it is to do with emissions, it could damage the cat.

Really need to get a TechII on it.

Don't think you will do any damage

A serious EML limits the car

If its the emissions one, only serious and damaging if it is flashing.

Saying that, any light on and I would be driving calmly & serenely until I knew what it was.

Just noticed the original wheels for your car for sale over on ABS

The garage I use has another branch a few of miles away with Bosch diagnostics that is able to read the fault codes so took it over there at lunchtime. "O2 sensor - bank 1" was the error that came up so am going to get it booked in for new sensor. I'm going to Devon this weekend but I was told it should be ok to make the journey before I get the new sensor fitted. Anyway, EML light is now out.

BTW Jimbob, how do you know the wheels for sale on ABS were my originals? Is it Big Rod selling them?

[Jimbob]

Yes, and the photo is of them on your car

Ah........that would explain then I don't have access to ABS as I'm not a registered member yet so I was unable to see it.

Thats not conclusive enough to warrant changing a sensor.....plus there are many lambda codes so do you know the specific number?

Do they have the facility to remove and ultrasonicaly clean the sensor?

Mark, you've completely thrown me there - I've really no idea. The guy doing the diagnostics just told me it was an "O2 sensor, bank 1" error. He also said he thought he detected a very slight misfire on tickover but I haven't noticed it at all.

So.......what to do next?? What would you recommend Mark - a trip to Nottingham?
Otherwise I was just going to book it in to have the sensor replaced, but you've put doubt in my mind now.

Take no notice Bob, its past its best and because your a nice bloke I will give you £500 for it.

At best, you're missing a 0 from your figure.

Full marks for your perseverence though Pete - you never know, one day I might just give in and sell it to you, but..................................................................................................................................................................................................................................................................................................................................................................................................................................................................NOT YET!!!!!!

3.2.... I bet I can guess the code!!!!  

P0420 Bank1

P0420 Bank1

Is this common with the 3.2 then?

Both SP3_2 and myself seem to suffer the problem, if I stick to one brand of petrol it seems ok.

I have an OpelScanner now so I can check whats being stored and reset if I want to (The lamp comes on when the number of logged 'bad' readings from the sensor reaches a pre set level or 'threshold')

Personally I'm going with the theory that the post CAT sensors don't get as hot as the pre CAT ones and hence they don't get burnt clean with the heat. As MDTM suggests, you can get them cleaned (need an ultrasonic tank really). New ones are £71 from VX, I wouldn't touch any cheapie no genuine ones.

Also.... Tesco 5p off stuff will put the lamp on without fail!

I put either Shell V Power, BP Ultimate, or either BP or Shell regular unleaded in now and the lamp hasn't come on for about 10 tankfulls (However, the codes P0420 (Bank1) or P0430 (Bank2) still get logged occasionally, just not built up enough to light the lamp)
