Omega Electrical and Audio Help / Re: Code 94 Hall effect switch Voltage high

« on: 08 October 2010, 18:01:59 »

They are right at the top front of the engine. Between the camshafts right next to the metal cambelt cover bracket thingy.

Ok doesn't sound too bad, do I need the cambelt and pulleys off to access it?

Have you checked the wiring as I suggested above.  V6 cam sensors don't fail. Their cables sometimes get caught under camcovers, aux belts etc etc...

Going to pull it apart this weekend will check more wiring at the same time - its a 200 mile drive to work on it! If that doesn't sort it it's for sale as is or by weight!

Hall sensor is the cam sensor. Never seen one fail on V6, thus not sure on symptoms. Check wiring.

Thanks, any ideas on where its located and what sort of a job it is to get to? Tried the earths i could find already.

My Omega has had a wobbly, it will just about run badly when forced to start on straight lpg with the EML on continually but will not run at all on petrol, i've replaced the crank sensor but that made no difference. Now also showing a auto gearbox fault on the matrix, but am assuming this is related to the running problem.
Had a scanner plugged into it while it was running but this was the only continual fault.
It was running fine on 6 cylinders, then turned it off and it wouldn't restart.
The only thing out of the ordinary was when i turned the key the traffic master did a report like you had just pressed the button. 
Any idea which sensor is the hall effect one, had a search and google but didn't turn anything up,
Ideas please???

Omega General Help / Omega 2.5 V6 aircon problems

« on: 19 July 2010, 22:08:22 »

Having problems with my aircon, don't think it has ever worked in the 3 years we've had it. I had it re-gassed but the compressor doesn't kick in, tried to bypass the low pressure switch but it has made no difference, I still don't have a feed to the clutch on the compressor.
I'm assuming the low pressure switch is the one on the top of the pipe with 2 connectors and not the one in the photo below

If anybody has any suggestions i'de be greatful becuase its making a good greenhouse at the moment.
Outside temperature sensor is faulty can this make a difference?
Thanks

Omega General Help / Re: Old Tyre Removal

« on: 19 July 2010, 21:21:50 »

Take valve out to deflate - drive car carefully over tyre (not wheel) to break seal - then use a couple of tyre levers to remove tyres from wheel.

This works well although with a light car to drive over it you may need to leave it on top for a while or move the wheel round a couple of times while adding fairly liquid to break the bead

Omega General Help / Re: 98 elite 2.5 - IDLE PROBLEM DEFIES EVERYONE!

« on: 24 June 2010, 19:04:19 »

I had a similar problem with my V6 - it was fine on gas but on petrol when warm would idle from 1200 upto 2000 rpm then drop abruptly back down to 1200 again increasing back up again, had the plenum off and cleaned everything in sight with lots of carb clean and compressed air, put it back - exactly the same, broke paint seal on idle screw, never been touched before, backed it out (a lot) - problem solved.
