Aug 2006 at 08:05 Have you tried the paperclip test to confirm it is still the Lambda sensor playing up. Maybe able to check for you later if its any help to you. Have a spare off the car at the moment I maybe able to tell from that.

If the sensor is the correct type I'd say:

white x 2 can connect to red and white, either way round.
Grey to yellow.
Black to black.

However I've got a feeling you may need the other type of sensor.

Some Vx use a 4-wire Titania Oxygen Sensor some use a 4-wire Zirconia Oxygen Sensor

Have a look round here: http://www.gendan.co.uk/category_111.html

I think it usually takes about 30 good starts before the code is cleared.

Hi

For info concerning the Lamba (oxygen) sensor, check out Marks DTM excellent guide here:

http://www.omegaowners.com/forum/YaBB.pl?num=1155557056

I would strongly recommend replacing your sensor (assuming that it needs replacement) with an OE unit NOT aftermarket.

Are you sure that the connections are good and that you have a good electrical ground?

Just had a quick look and looks OK to me. I am guessing that you have the 2.0 16V engine (the X20XEV). This, I know, has a heater element. I don't think that the ones on the V6 (there are two on this engine!) do.

I have read elsewhere that Vauxhall Spares Centre are good so you should be in luck.

Have no idea what the main dealer price is, but £64 looks good to me.

As to resetting the ECU - what you have been told about the battery disconnection is TBH rubbish. You will need to reset the fault codes not the ecu! This can be done with a code reader called Tech 2. Some members on here have this and would possible do it for you.

Gunsons also do a code reader, available in Halfords, but I am not sure about it's ability to reset faul codes.
