Omega General Help / Re: Failed on emissions again.
« on: 24 April 2022, 16:31:22 »
Thanks Raeturbo, just watched it.  I don't know what the TPS voltage on mine should be at idle(rest). It shows as .53v at idle and does move when throttle is moved. Would anyone have the voltages at idle and WOT, so I can compare them to mine?

If the voltage is too high, before the throttle is touched, then am I thinking right that the ECU, would be thinking the throttle is already being moved. And possibly put more fuel than is needed, but all the other sensors are possibly working correct, so the ECU is confused causing O2 sensor, to do what it wants?

Hi dave the builder. The only ones that sound something like LTFT and STFT readings are O2-Loop BLM Idle (Block Learn Map) and O2-Loop BLM Partial Load (Block Learn Map). They are in the live data, I posted links to on first page. :y

Raeturbo. The TBS is showing .53v, then every now and then .55 without me touching the throttle. Is this right or should it be showing 0v, if I am not using the throttle?

Thanks for everyones help and advice. It is much appreciated. I understand that all advice, might not fix the problem, but if I do one at a time, hopefully it will sort the problem.

Thanks for the info dave the builder. I have a injector tester, that will do the pulse for cleaning them, bought it at the time, because the price was good. Justified buying it to myself, as a you never know ;D.

Doctor Gollum the wife has only put shell or BP good stuff in it. Even when we had unleaded and Super unleaded. :y

I have been told by someone who owns a 2ltr, said the 2ltrs are prone to the valve seals going. Apparently he had it on his, which gave the same problem as mine, high Co emissions.  I have not heard of this before, has anyone else?  The seals were done on when the headgasket went, on the wifes 2ltr. Is it possible for a seal/s to go bad, even if service the car regular, due to the wife doing lots of travelling in it? I really don't want to disturb the head, unless I have to. If I remember, once the intake manifold is removed. I should be able to see the tops of the valves. My thinking is that if I remove the intake manifold, then I do a clean on the Throttle body, even though it looks ok. And also see the injectors.

Hi dave the builder

I have been thinking, that maybe they could be dirty. Have been looking at the kits, that fit onto the fuel rail and use pressure. But unfortunately don't have or know anyone with a compressor. I was thinking of taking the intake manifold off, as I cannot find the parts code for the O rings, so don't want to disturb the injectors and damage the seals.

Not recently. I had a mechanic, who has done them loads of times, do the last one. It will be due another change soon. But I could remove the covers, now just to check everything is still spot on.

Never had emission problems until recently. I even had a old 2.5, that when it went for a new belt and water pump, that it was a tooth out, it never failed emissions test. Are the 2ltr 16v more picky on not being a tooth out?

Hi dave the builder

From recommendations in the old post. I changed the ECT. MAF, Idle Air control valve. A new correct for engine Genuine NGK O2, exhaust from cat back, with a Type approved cat (well it was purchased as a type approved, as checked before I bought it). Fitted a Gates thermostat, that was linked by Doctor Gollum to me in the old post. In the old post I did the other suggestions aswel.

l I have another new O2 sensor coming, as someone in another post, with the same sort of problem on a 2ltr. Were saying they had a O2 that was leaking, letting in air. Just incase the one on the car now has the same problem?

I have done a vacuum test which shows ok. Checked plug wells for oil, nothing. From what I can see, no richness or oil showing on spark plugs. There is no smoke from the exhaust, just smell of petrol. I have a new Throttle body sensor, to replace the one on the body, not done yet. I have looked inside the Throttle body, both sides of the butterfly to see if there is a build up of oil. It looks clean.

I have not touched the EGR Valve, but was thinking of removing it and blanking it, just incase it has failed. Also looking at getting a new manifold, without the fittings and holes, for the air system and EGR,

I have bought a O2 reader tester, that does Titania that allows you to force a rich or lean test. I was going to back probe the O2, then see if the live data, changes as I force a rich or lean. Does this sound like something worth doing?

As I said before, I am not sure if it is "My Naff Code Reader" getting confused, with it being a 1995 model and a Titania O2 sensor. So as the voltage goes from high to low, it shows it as closed then open?  Unfortunately I don't know anyone who has "My Naff Code Reader" and possibly a 1995 2lt, to see if they have the same thing going closed to open.
 
Thanks to everyone, for your patience and for all you help and suggestions. Much appreciated.

Hi iansoutham

Thank you for replying to my PM. It is very helpfull and interesting.  Have been looking and think I have found a couple of Type approved 2.2 cats?

I know Klarius used to be quite good.

Hi Enceladus

Sorry for delay, been busy with hospital appointments.  The cat that I fitted EEC VX8020T type approved cat. I did the fan disconnect test, it made no difference. It was still going close to open. Would it be because the O2 sensor is Titania, so the data from the "My Naff Code Reader", shows as going open to closed as voltage changes, with car being a 1995?

I have got a new genuine NGK O2 sensor coming. As I read on here someone with the same as mine, had a leaking new sensor. Also going to fit another new ECT sensor, as you said one on car is still showing as cooler than it should. In another topic on here from someone having the same problem. A member iansoutham, said he always had emission problems.In the end he put a 2.2 cat on with a blanking plug where the second lambda goes and he ended up with 0.03% co.

Do you think this is something worth looking at, as I have found a  BM 2.2 type approved one. It was mentioned pattern cats are rubbish. I do have a old registration, for a 2.2 I had as a Registration No is usually asked for, before they sell the cat.

Thanks for your help. Much appreciated.

Changed thermostat for a Gates, all sensors recomended to change i did. Cannt remember radiator sensors make sorry. It passed last year.

Done some live data today from car being just started, to fan coming on then off. Did a vacuum gauge test, that stayed in the green at 19. Checked spark plugs and wells. No oil and plugs seem ok. Managed to record a osciliscope of the O2 sensor at idle to a bit of revs and one at 2500revs. Also recorded the sensor going from closed to open as the voltage changes, also the Block learn readings.

all plugs looked like this

Omega General Help / Failed on emissions again.
« on: 14 April 2022, 22:34:30 »
Well took the wifes 1995 2.0ltr 16v Omega, for its yearly MOT. And again it failed on the CO on fast idle test. And just scraped through on idle test.

It went through last year, just scraping through on the fast idle, but idle test was really low. I changed the exhaust from down pipe to back box, including a type approved cat. I changed ECT sensor, genuine NGK Titania O2 sensor, that was checked directly with NGK, to make sure I had the correct one,thermostat and other parts, as suggested on here the year before.

Here is the link to the conversation. https://www.omegaowners.com/forum/index.php?topic=145812.msg1921223#msg1921223.

The CO is well out of range, this year. As can be seen by the fail sheet. I took the car, the long way round to the MOT place. And it was hot, when I got to the place. Fan also cut in just as he was about to test emissions. As you can see he tried the test twice, with no luck.



 I did some live data, a few minutes after I got home. So car wasn't cold, fan did cut in as I was recording the data.  Can anyone point me, to what could be causing this problem?

https://drive.google.com/file/d/1BEAYkCx-ps0gppKL93MeB02rre7HWO3c/view?usp=sharing.

The one thing I did notice, but it seems to have always done it, is that it goes from closed to open loop, as the O2 sensor voltage changes. I don't know if it is, the thing that cannot be mentioned to I used to get the live data? But the voltage fluctuates up and down quite quickly.  There is also a smell of petrol from the exhaust, when on tick over.

Thanks in advance for all help.

The hospital will keep him in untill they are happy to discharge him. And they will not let him drive. Untill such times they are happy, that he is safe to do so. If he does drive, more fool him as he could possibly lose his licence, also his insurance company will not cover him, in the event of a accident. It was ages before the hospital let me drive. Now I am going through a medical again, to see if I will lose licence completely, as they aren't happy with some things.

Omega General Help / Re: EP90 Diff Oil
« on: 19 March 2022, 08:52:21 »
I have been looking around for another diff, just incase replacing oil on wifes car, doesn't solve the problem.

I have found one, that is from a 03.1997 2.0 16V petrol 100kW 136PS (X20XEV) with a 5-speed manual transmission (GJ 062 97 A). From my understanding, even though this one is a manual and the wifes is a auto the gear ratio is the same one on the wifes car. Is that correct?

Thanks for all your help.
