Omega General Help / camshaft sensor

« on: 22 July 2010, 18:20:45 »

I've got an Opel comodore 2 ltr 1998 with the motor service light on.
checked the codes and they tell me an error on fuel injectors 1-2-3 and 4 but that seems normal as the car is running on lpg. the other code is for the camshaft sensor .
I checked the output of the sensor on the scope and that gave me a Sinus wave form of 3 Volt p/p
should that be a square wave?
Also, should there be a 5 Volt supply to the sensor ? there are three wires .
Earth- Output - and supply ?
please somebody, I've got my knickers in a twist.

Omega General Help / fuel injectors give error codes

« on: 10 June 2010, 12:50:58 »

Hello everybody, hope somebody can get me some advice.
The car is a Opel Comodore 2Ltr, drives on Petrol and has a Koltec installation as well.\ Acelleration is very sluggish from standstill and if I put my foot down too much, the motor gives a ' throaty'   sound but does not develop much power.
Driving on gas, the engine light switches off, but if I switch to petrol, the light comes on and stays that way.
When the car has speed, performance  is not too bad but still not particulairly good either.
No difference to talk of, in either gas or petrol mode.
the codes read: 0201 to 0204 than 0304 and finally 1690.
I have changed the camshaft sensor already but that did not make a difference.
A while ago I cleaned the small breather hose with the ventury on the end. reason was that the motor would stall on occasion; cleaning the breather did cure that.
Again, I do hope that a kind somebody will give me some advice and a lead as where to go from here.

greeting and much regards

Eddy Moors.

Omega General Help / Re: fault codes

« on: 21 May 2009, 21:55:52 »

Thanks for the reply, the first codes, 0201 to 0204 , I think so too, must have a common cause, but what I would like to know, is there anything I can measure and what and where?, also, the engine bulb only lights in petrol mode,( not always but most of the time ) so I'm not sure if the gas installation has anything to do with it. As for the last code 0340, is that not because the engine not running while reading the ECU ?
Going back to the installer would mean Opel, I think the car came with it from the showroom.at least thats what I make from the papers that came with the car.
regards and greetings.

Omega General Help / fault codes

« on: 20 May 2009, 11:40:31 »

Hi everybody, after I had problems with the regulator of the dynamo, I had to replace several bulbs in the instrument panel, burned out, due to over voltage. (this might, or might not,have anything to do with this problem.)
Another thing I notice is that if I switch to petrol my engine light comes on and the paperclip gives me the codes: 0201-0202-0203-0204 than 0340 the last one i understand, the others say something about the injector valves being high, lo, or open circuit.
apart from the fact thatI really dont know where to look, how can I check which of the three it is and how to check it.
funny thing, the car drives like a dream and even the engine light switches sometimes off as it should.yesterday for instance, in the morning it was on all the time (in petrol mode) and would only switch off when I switched back to LPG.
A short time later however,it would switch on only momentairely at changeover -petrol/LPG- or back, and stay off, which is as it should.
Today again,  in petrol mode it's on all the time, but the car drives smoothly.
The car is a 1998 Opel Omega , motor x20xev and has a Koltec Egi installed.
Can anybody enlighten me, I would be ever so gratefull !!

Newbie Welcome Area / My "New Car"

« on: 20 May 2009, 10:59:20 »

Hallo everybody, I'm living in the southern part of the Netherlands, close to the Belgian border (thanks heaven) where it is a lot cheaper to get fuel than it is on this side of the border.
I'm 62 years, an electronics technician, selfemployed.
My car, (an Opel Omega station car 1998) has an Koltec Egi system, so, apart from the dreaded roadtax, it's quit cheap running.
I have this car only since beginning februari and I'm trying  to find out as much as pos. about it so i 'm able to do as much maintenance as pos. myself.
Sofar, I've replaced the sparkplug leads, cleaned and fitted a revision set to the gas distribution unit, replaced faulty dynamo, replaced burned out instrument bulbs in the dashboard panel and found out how to do the paperclip trick.
I still like the car, drives like a dream if all is well.
however, there have been some moments that i cursed the bloody thing and wished i'd never set eyes on it , so it's a little bit love/hate affair.
anyway, I'm happy to have found this forum and it has already given me lots of info, thanks for that !
Grtz, Ed
