I have now replaced The ecu with à "new" one. Still no better. Exactly same Fault codes.



Find one person with same problem and codes:
http://oldsite.omegaowners.com/forum/YaBB.pl?num=1313139703/0

As vauxhall/opel garage experts have adviced me To replaced egr and ecu. (I did)
I still believe its The CAM sensor. Iam gonna talk with them this monday. And demand them To replace it altough they say its nothing wrong with The CAM sensor.

To be Continue.

Perhaps it is the cam position sensor that needs to be warm 

I imagine you have already done so but I would check all the connectors around the ECU & battery (including the big circular connector and all the earthing wires).

Unplug the connectors, quick squirt of water dispersant, and plug back together (making sure that the locking ring is done up on the circular connector).

Unbolt earth leads, clean off any rust and bolt them back on with a smear of copper grease.

.. and an ECU fails so rarely it's not even worth considering. Mechanics suspect that when their (limited) diagnostic capabilities are exhausted because it's complicated and expensive.

ECU failed in 02 Saturn 3.0, which is Omega engine, even ECU fits both cars. I used ECU from Catera. Random codes are sign of ECU problem or ECU ground.
BTW I replaced throttle body in the Saturn first, which didn't help.

This looks like a problem with the DBW throttle system, so throttle position sensors or pedal position sensors or associated wiring playing up perhaps?

Need to check all 4 (2 sensors in each) using live data, IMHO.

I have done all that. The new ECU got the same fault codes as before.
The opel/vauxhall garage have now replaced cam sensor. (as i told them to do in the first place)

The car now works normally. And shows only one fault code. p0700. (mil req gearbox).
How do i remove that code?

Only i have done is cleaning the contacts to gearbox (ofcourse without battery in).

So tired of this now, the car seem to be working as normal but stil electrical spanner light in dash. and p0700. =(

Regards.

That may be a remnant of the cam sensor issues as it often throws up transmission codes, it may clear not sure but can be cleared with a reader but I would have thought Vaux would have done it. Glad the running problem is sorted

They have tried cleared the p0700 but it still comes back, i have no idea why.
Where could the problem be? Iam gonna try connect the old ECU back to see if the code dissapear.

Yes the car operates normal and there is no limp mode. (should p0700 set the car in limp?)

Thanks for the help everybody.

[leebron]

Iam not gonna say that the car is 100% cured but today it works and there is no more fault codes.
Had to clear fault code p0700 in automtic gearbox ecu first then clear it in the engine ecu.
The car now operates normal and iam positiv and hopefully there is no more now.


Just wanna thank all for reply and say that you all has been more helpful then the vauxhall/garage who made me pay for lots of unnecessery parts to finally get them to fix the fault (the camsensor).

I now have one extra throttle body, egr and ecu as spare parts.

[Rods2]

Unfortunately, making customers pay for parts they don't need where the Vauxhall mechanic hasn't a clue how to interpret the fault data is all too common.

mate had same car and problems-he scrapped it
