Omega General Help / Omega 3.2 P0130 P0150 fault codes triggered

« on: 07 February 2025, 18:10:10 »

My ecu throw up recently codes P0130 - P0150... i checked and they are connected to the oxygen sensors that are running near the precats so my questions are as follows:

1.
I hear a rumbling noise on startup ,and when accelerating it seems that comes arround manifolds - possibly a manifold to downpipe gasket failure,could this trigger the sensors error?

2. If Yes to 1st question,could it be reason that i am getting a 22 MPG fuel economy on a perfectly straight road doing 80mph,or this sounds like normal consumption... 3.2 estate with auto box...

3. I tried to find on forum,but did not suceed,if anyone has put 3.0 downpipes that have no pre cats,how the car reacted,and what to do with 2 oxygen sensors then,will they trigger the error,or do i need to switch them off in some mapping session or whatever?

Thanks in advance

Omega General Help / Need advice on purchasing 3.2 Estate auto

« on: 17 December 2024, 03:47:39 »

Hi guys!

I am about to see one Omega this weekend,finally i found one that i like,it is good equipped,rear seat heating,sunroof,trailer hitch,etc...

It is 3.2 estate with auto gearbox and the mileage is 156 000 ...

What should i look for,especially regarding auto box? Are they reliable items? Engine mileage ?

-cambelt is changed recently
-although i am driving v6 items for 10 years now(on front wheel drive

)all my v6s have been low mileage ones,and never gave me problems regarding mechanical issues...so my concern is about this 156 000 miles...

Any other quirks i should look for? Thanks

Omega Electrical and Audio Help / X30XE facelift - i need help for correct crank sensor

« on: 05 January 2022, 17:51:52 »

Hi folks!

I recently put x30xe management on my Y32SE...
Before that it had c25xe management and i bought week ago original GM Bosch metal crank sensor with square plug,as stated it fits omega 2.5 V6 94' ,all calibras 2.5 V6,vectra B 2.5 v6...everything worked good until i put 3.0 loom and management

Now with x30xe management i have fault 19.I suposse the ECU doesent like the old metal bosch sensor.
It is facelift 3.0 ECU with letter coding AF.
I need help from experienced owners to confirm me that i dont need Siemens type of sensor,if we reffer to this topic...

Omega Electrical and Audio Help / X30XE ECU differences(automatic car vs manual car)

« on: 21 November 2016, 14:03:56 »

Hi folks...is there any difference between ECUs or are they all the same..for example will x30xe auto ecu work good with manual loom and gearbox?...i noted there are HJ and AF x30 ECUs but concluded that those letter marks are random regardless of auto or manual car....i put manual loom from x30xe but im afraid if i buy ECU from automatic car that it will not work good

« on: 01 October 2015, 14:58:42 »

As you know i transplanted x30xe to calibra..i menaged to bypass the immobiliser..however when i start engine(cold) i got EML staying on after 15 seconds of car working...i get following codes in this particular order when doing paper clip test
12 - initiation of diagnosis
135 - tail light,this is not connected in calibra so its normal to be registered
46 - secondary air injection pump,also not connected in calibra..i welded holes on exhaust manifolds
-----------------''''----
17 -knock sensor circuit 2
129 - egr voltage low
63- inlet manifold valve 1 voltage high
73 - maf sensor voltage low
Car is running like shit,stuttering in neutral and when driving,giving a puff of black smoke when hitting throttle...other than that there is no blue or white smoke at least....
