Unplug the MAF sensor and see if  the car behaves better. If it does it points to a faulty MAF. However, i've successfully cleaned mine on a number of occassions now by removing the MAF, taking off the plastic 'Portcullis' end and carefully using a soft bristled artists paint brush dipped in Isopropylene Alcohol, cleaning the sensor wire then refitting. It is certainly worth a try before spending your hard earned! :y

Hi my 2.2 did that sort of thing...would not rev and when driving under load sounded like a machine gun...turned out to be the lamda sensor..the first one nearest the manifold...changed that and all was fine.

I would get the codes read again ... i bet the P0340 is still there .
Was it a genuine cam sensor ?

Symes, my cam sensor was from the headington auto parts, not vauxhall, And I;m sorry but I will not be spending more money and getting a vauxhall cam sensor, if its not up to the job, ill break the car, its clearly not worth having as all other cars I have had have taken aftermarket parts and they have worked, if this is what omegas are like then its my last

Hardly a fault with the car if some pattern parts are substandard  ???

Although, given your symptoms, I don't think there is a cam sensor fault at this stage
Title: Re: 2.2 petrol engine fault codes
Post by: Boggy on 10 December 2012, 21:23:01
I just don't understand this fault I have, it ran fine after the head was done, its just gotten worse over time, the air leak was a seal on the injector which was replaced with Vauxhall parts but although it fixed the leak, its amplified the bogging down etc? Symes done the cam timing and now it wont rev over 3000rpm? I don't have alot of money with Christmas to keep buying parts on a whim, if I sold it for spares or repair, I could get a cheap diesel as i just need to get to and from work, luckily I have the neighbors car for the short while into January, shes a learner so not using it through the week. Were you going to pop into symes with a tech 2? He mentioned you, I work odd hours so that's Why Symes has the car at the moment

That your main problem .... "whims" .. it needs PROPER, logical diagnosis.. not "lets try changing this today" ....

IMHO

all parts were based on fault codes, not a tech 2, cant remember what it was now, TBH I don't really care for the car now, Maybe if it gets fixed my interest in it may grow but for now, I have no expectations other than bad news, sad as it may be, I'm a little disheartened I had plans to make it a nice motor even though its already a tidy car already

I needed a cam (or was it crank?) sensor for my Saab recently, a genuine Bosch item was sourced from my local Motor Factors for around fifty squid, you don't have to pay dealer prices for dealer parts all of the time...

Fault codes aren't the entire story. Sadly many garages believe they are.

We'll get her on the Tech2, just not sure when I can get over  :-[

RobG has just answered your question stevo1985 ???

P0340   Camshaft Position Sensor Circuit No Signal
P0340   Camshaft Sensor Incorrect Signal

Your original GM sensor is faulty, as was the Pattern part you bought! :(

No.

The symptoms described are classic symptoms of a blocked fuel tank breather. Next time it happens try loosening the petrol filler cap and see if it sucks a load of air in.

Still battling with this problem still p0340 checked timing ,have genuine  cam sensor checked wiring all ok,
I'm thinking the only other thing would be the ecu, would anyone agree?
Title: Re: 2.2 petrol engine fault codes
Post by: tunnie on 28 December 2012, 19:29:14
No.

You had the cam sensor "checked" but have you purchased a replacement genuine one?
Title: Re: 2.2 petrol engine fault codes
Post by: stevo1985 on 28 December 2012, 21:05:36

I cleared all codes just getting p0340 now, code clears ok but when I go to start car warning light comes back on and code up again! Gearbox isn't changing good either but thought that was down to the engine not revving out properly?
Any help much appreciated

OK, does point to cam sensor.

So, if you are sure the cam sensor is ok, check its pick-up, cam timing, and integrity of wiring back to ecu.

ECU is very robust, so at this stage, I doubt its that.

I have the launch diagun x431 diagnostics
I've checked timing and all ok
Still p0340 code 2day
I have checked wiring from sensor to ecu and testing ok ::)
