Right, it all good at this point, only thing on EML is code 89, the code list says its the oxygen sensor heater.
So whats all that about then? Oxygen sensor heater? :-?

Lamda
-
89 - open circuit to lamda - check connections on sensor.

Lamda? So wheres that then :-[, sound like a south american dance step to me! ;D

On the exhaust - one on each side, measures oxygen in exhaust gas, which ECU uses to richen/lean mixture...
-
Right gotcha, just read a thread saying that is could also be the coolant temp sensor causing the 89. Is that credible, and if it is wheres that one? ;)

Be surprised if coolant sensor could cause, but lamda fault won't happen until coolant 70C. Coolant temp on V6 is on coolant bridge, at the rear of the banks, under plenum...
-
Just checked the connections, and they seem fine! :)
Done paperclip again and now as well as 89 its now coming up with 135, any idea what 135 is? :-/
-
135 - EML not working.
Usually spurious when other codes present....
-
So with 89,s connections looking ok I can assume that the lamda sensor is shagged, and I assume both of the need to be changed??

89 is sensor 2, so just that one. But you need to meter it through - lamdas are expensive (and delicate!), so make sure it is that first. Unless you're nicking a couple from scrappy :-X
-
Is 2 the pasenger side by any chance? As some of the wire cowling is off that side, although connections seem fine.
'But you need to meter it through' Well that went straight over my head mate ;D
And these things are pricy? How much do ya recon.

The following site has oxygen sensors for the 2.5 and 3.0 for 25 pounds. (DOwn the bottom of the offers page). :y

Hope This Helps Karl

No offense meant or intended, but I have always read and been told that it is not worth using anything but OEM (genuine parts) for Lambda sensors.
I know of a colleague at work who runs a Corsa. Her sensor was replaced and she was pleased to have got in done cheaply due to a non OEM unit being fitted. The car was back in the workshop two months later as the new sensor had failed. She insisted on a genuine item being fitted on my advice. That was six months ago now.
-
Believe me if i could I would matey!
But its gonna be an OEM from the scrappy in the morning ;)
-
Sounds like a plan. I would be interested to hear how you get on with removing the sensors from their respective downpipes. Remember that the are very Fragile when removing them.
Two other thoughts - are you sure that the wiring from the sensor to the loom is not suspect? Check to see that there are no cuts in the wires, the wire is not rubbing on the chassis / engine etc. Sometimes the sensors can appear to have failed as there is no earth. You may be lucky and find that if you loosen the sensor, clean up the threads removing any corrosion that you may find, and refitting it, the earth will be restored and the sensor works again. Worth a go and won't cost you anything.
Hope this helps.

Dunno if it has any bearing, but before the lambda sensor went tits I was checking and tightening the breathers at the back of the plenum. On starting the next morning the EML was on and the 89lambda came up on the paperclip. Before messing with the breathers this the EML wasnt on! So I was wondering if there is anything behind the plenum that I may have pulled or knocked to cause the 89 lambda!
Just a thought before i try to take the lambda of and clean it up in the morning.
Oh and which is lambda 1, and which is 2?
-
No lambda's at the scrappy, no cash left in the car pot, no choice but to sell, what a waste! :(
-
Im off down the scrappy tomorrow, i'll have a look at the car I got my 3.0 MID from, didnt have engine, but sure exhaust was there, if the lambda's are there i'll get both for you......
-
Much appreciated matey :y
But to be honest, not that Im able to but i get the Lambda done, and its prety much a dead cert that theres just somthing else waiting to go wrong the following day. Typical of the fukin luck we have had lately! So although Ive done a lot on the car in the last few weeks, and I realy like the car, its going mate! Just spent £52, which is a small fortune to us, on the crank sensor hoping that would sort a few things out, and all it did was take the 19 fault code away and nothing else changed. I guess there are those that would say, 'If you cant afford to run a car, dont' but we can, just afford to run a motor, but can no longer afford to constantly spend out on it. Its cleaned us out and we got no futher foward with it. Its realy important that we have a reliable car for our boys needs so I got to bite the bullet on this one
But cheers for the thought matey ;)
-
These codes would not worry me to much as given the history, its possible the sensor is simply sooted up a bit.
Some driving about would probably clear the fault......as the code basically means the sensor is responding slowly so it thinks the heater is not working (it cant check heater operation)
-
:y No problem mate, if you do keep it by any chance, just let me know as I dont mind helping if I can..... if I got em for you I wouldnt want any money besides posting or I could meet you somewhere ;)
If you are selling it, I wish you all the best and hope it makes you some profit :)

Cheers John, no profit to be made matey. Have put it up for 825 which doesnt even cover what I have spent on it after purchase price, but i dont recon I would get much more than that fo rit anyways

Sorry to hear this mate - have you not though about doing what Marks DTM says? He is usually if not always right in what he says..
Just a thought.

Yup I know, all of the advice Ive had of Marks been sound, took it on a 40mile jaunt yesterday and it made no differance matey. ::)
Just been offered £500 for it though, told the guy to go buy a scateboard for that! ;D

Any idea what car your gonna get next Owen? if you sold your current meega, you could pick up another bargain, just make sure you give it a good test drive and inspection, since you have come across many common probs with that omega, you will know where to look on faults with a new one :y
-
Lambda sensors can sometimes be revived by taking them out and heating the tip in a gas flame (i.e. on a kitchen hob or using a blowtorch).
However, if they've been in there for a long time, there is a risk of knackering them while taking them out. Hot exhaust gas will probably do just as good a job. If you can give it a long motorway run it may help.

Would idealy love another meega, age unimportant as long as its a good one, but will go over the next one with a fine tooth comb now I know a little about what makes them tick. Thats if I get 800 for this one. If I find another and there a forum member in that area I recon it would be wise to ask them to look with me.
Wish I had the confidence to take out the Lambda's but yesturday I tried to take one from a V6 Vectra in the scrappy, just to see how easy it was. Got it to turn freely, but couldnt undo it all the way, it just got tighter the more i tried to loosen it. So im hessitant to even try the ones on my meega incase i break somthing, which I realy dont need when im trying to sel it.

Cleaning in an ultrasonic bath works much better.....can also fix the ones damaged by poor supermarket petrol to.
-
Out of curriousity is there some knack to getting them out?? When I tried it on that scrappy vecy I loosened it, and could turn it with me hand, but just a few inches worth either way, but after futher turning it just tightened and locked, so much so me ring spanner broke on it!
-
Its luck of the draw and not unusual for them to stick and strip the threads on the sensor.
-
Well, im just popping to scrappy now, i'll have a go at getting one off without damaging it...... I need a new rear console bit for the air vents and fag lighter, the cops in their infinate wisdom decided that they wanted to hacksaw the back connections off for the air hoses instead of just removing the pipes. I'll let you know how I get on ;)
-

Never thought of trying that. I shall remember that one. Nice tip :y

Well been to scrappy, managed to get what I needed, but the car with the sensors has been put on the ground now with 2 astras ontop of it, so cant help you there owen..... I checked some vectras out, but non were v6's :( sorry mate I did try.
-
no probs matey :)
