2.5 Omega Engine Management Light

Jan 29, 2005 4 Replies

Earlier today after accelerating to overtake in my 1999 2.5 Vauxhall Omega the engine management light came on and has been on ever since. The engine is running smoothly with no loss of power. It starts, revs freely, idles and stops just as sweetly as ever but the engine management light is still on. I have made several trips today with no problem except that the engine management light does not go out.



I am booking it in to my local vauxhall dealer this week to have it checked, but in the meantime does any one have any idea what it can be.



Thanks.........


Hi,

I've only got experience of Cavalier ECUs (few of them good!), but usually you can short a couple of pins of the ECU connector plug to make the ECU light flash a code on the dash to tell you what's bothering it.

This web site should be able to help:

HTH,

Just got back from the Vx dealer.

Turns out that the Air flow plug had become disconnected.

Good news. Significantly cheaper than a broken air-flow sensor!

Cheers,
