Reseting the Lambda Light OBD II

[cameron]

After a mad dash over to Lancaster the other day, The Friday before my old man passed, i was calming down to the usual 30mph when the Lambda light came on

It didnt bother me at first as i though hey ho pop the bonnet and use the Self Diagnostic unit to reset it

EH NO !!!!!!!!!!!

Got home and realised i couldnt as it was the OBD II port instead

Is there a way of resetting it without going into the expense of a garage visit ?

Sorry if this is an old question, i have used the SEARCH facility but i cant find anything, probably not looking really

Cheers guys

take the bulb out!!!
my dash is lit up like a bloody christmas tree at the moment but it still runs fine.
i think these are a bit too eager to throw faults up...

[cameron]

That was an option but id rather leave it in and just turn it off

Hi lee was good to have another meet the other day, if there isnt a problem with the car it should go out on its self with a birt of time other thing to do is dissconnect the battery for 10 mins and see how it goes from there i would cheack all hoses first with booting the car one could be loose

I would sort the problems the code/s are indicating before trying bulb removal which is a definate no no imho. Fuel trim problems can cause codes to be thrown up with no apparant alteration in performance. The codes are thrown up for a reasonso it is best to sort them when they appear.

the bulb removal bit was meant to be a joke
but some cant afford to go running off to the dealers or specialists everytime the car throws a light up

un plug the lamber sensor clean the connectors, brake cleaner or WD40, and plug it back together, my lamber light came on after i drove through a ford, about a week later, the light went out about 1 hour after i cleaned the connector.
check all the hoses for a leaks as this is a common problem split hose.

t5pete informs me running an MBC and by-passing the BCS will throw the light on
so thats me sorted

Probably a air induction leak as you dropped speed...
I would remove the ECM overnight myself and expect the light will go out, or
follow the link from Wambatbom using either a LED or analog meter...., a digital meter will be too slow to delete the code...
A 2-3-x code would be my bet

just disconnect the battery for an hour, and light will be out, if fault is still there light will come back on. Just make sure you have radio code b4 disconnecting battery
