Title: Omega Starting Problems
Post by: Scotty on 13 September 2007, 09:16:16

How do everyone,

I have recently had a few starting problems with my Omega 2.2 Auto.

Having had the RAC out to my car outside my house he was 90%
certain that the cause was a faulty camshaft sensor even though no
warning light was not appearing on the dashboard.

I took the gamble and had a new camshaft sensor fitted and now the
car is starting first time. However, when the car is now started
for the first time the warning light (this looks like a spanner on top of a car)
now appears. If I stop and restart the car the warning light disappears.

I was wondering why the light was not coming on in the first place to
suggest the camshaft was indeed faulty? and why when the new sensor is now fitted
does the light come on intermittently?

Does the warning system need to be reset as you would do with a PC when a new
device fitted??

I would very grateful if anyone has any answers to the questions above.



Thanks in advance.


Andy

seen a few where the cam sensor is faulty, but not flagging it.

As to EML now, need to get codes read to find out what it is unhappy with...

Just a thought. Does this happen every time you start the engine or only intermittently? Does it only happen on cold starts?

Mine did this, worse on damp mornings, I used to pull over and restart the engine. The Tech2 suggested a throttle issue. Marks DTM thought that this could be a loose connection in the drive by wire set up.

Fiddled with relays and wires and so far no further problems. Maybe a loose connection somewhere?

As said, just a thought and by no means a diagnosis.  :y
