    Default lambda question

    Does the vectra ecu recognise a dying(slow)lambda or will it just throw a fault when the lambda stops working altogether? As I have read that some cars will recognise a slow lambda and others wont....thanks

    Would have thought you would get the spanner light come on. Best bet is to take it to a dealer and ask em to Tech II it.

    I would have thought you would get the light come on too. This is my theory. The ECU has set perameters. If the Lambda is not working correctly it will tell the ECU incorrect data. If the ECU listened to the incorrect data ( and re-learnt it). you might find that it could tell it to over fuel and that eventually would distroy the CAT. Or even make the car run badly.

    What sort of things have you noticed that make you think it is the lambda..

    I'm sure the emissions light will come on rather than the spanner one

    What about disconecting the wire from the Lambda and see if the same warning light comes on.

    No guys Im not getting any light, A while after I got the car the emissions light came on. The garage I got it from ran a diagnostic and got a [sensor 1 bank 1]fuel trim so they cleaned the lambda.Have been told off of vauxhall that cleaning them can poison the lambda. Since then the car judders a bit like its missing when in slow moving traffic or low revs in any gear ,I was just wondering if anyone knew if the vec ecu would recognise if the lambda was not working correctly and a tech2 would only pick up a dead lambda.

    You been mis guided by VX again. The process of cleaning them WILL NOT poison them. The cleaning fluid might though! If you insist on cleaning it, then use a bit of petrol only. The sensor will be poisoned by phosphurous and sulphur.

    I don't think the ECM will detect a drifting lambda sensor until it goes out of range, then it will throw the light on, and revert to default settings (but not limited operation, I don't think) acceleration will be down, smoke will be up and so will fuel consumption.

    If you have a FC for oxygen sensor, then it's really best to replace it.
