Hi i have a 1992 k reg saff 4x4 just wondering should it have had a lambda sensor from new?There's not one in it now but could that be down to having a mongoose exhaust fitted and no boos included in the downpipe? can't find any straggling wires for a sensor.

 

i think a K reg one shoud!but not 100% sure is yours a green top lump?

 

If the ecu needed(and had) one and now it didn't have it, it would run like a bag of poo, so if running ok I would say no.

If its a green top engine it would of had the lambda sensor mounted in the turbo exhaust housing as standard from the factory.

 

My k reg has one fitted in the turbo as richie said.

 

It is a green top but wondering because it was chipped when i had it along with a mongoose exhaust whether somebody has done away with the lambda sensor as its chipped anyway kinda thing

 

What? mine is a green top and no longer has a lambda sensor and runs fine thank you very much

 

there is your answer, obviously the chip used was probably not capable of utilising the lambda sensor so it must have been binned.

 

but according to your sig yours has been live mapped lol, my guess is tabetha is refering to if the car still had the origional software, however even if it did and the lambda was missing i doubt it would make a massive difference to the feel of the car, possibly to the fuel consumption and the cats if they where still there.

 

Just got to find the wires for it now then,can anyone tell me or show me what they should look like?

 

black triangle plug,red core...around the brake pump assy/bulkhead area .

 

Cheers i'll have a gander now

 

nope can't find it

 

please stop giving out wrong info

 

check all the way along the bulkhead, it comes from the engine loom, over through the bulkhead under the abs unit, you should also have a purge valve by the power brake unit, connected to the carbon canister under the o/s wing.... via a vaccum hose

maybe, your car has had an older loom fitted,which didnt have a lambda....take the ecu plug off and make sure pins 1 and 2 are present and wired up.... one of these is lambda signal,cant remember which,,,,1 iirc








you can never assume a green top should use a lambda sensor, most tuners dont utilise closed loop,so its not needed when chipped....just like older L8 4x4s...

 

I can see some kind of valve down there,I'll have another look tomorrow gone dark now cheers jtechsaff will let you know

 

if the purge vallve is there and is plugged in, you have a green top loom,and should be able to find your lambda plug somewhere....

 

silky16v,
If you read the thread as I did it sounded like the question was asking if it should have a lambda and if someone had removed it purely because they had fitted a different exhaust, in which case I stand by my answer.
I am sorry I can't be as perfect as you, but I am too busy paying my bills.

it doesnt fit in the exhaust...its in the ex housing.....

 

Found it dangling down the chassis rail



there should be somewhere on the exhaust housing for the lambda sensor to screw into yeah?

 

Sensor goes into one of these?

 

yes and yes.....

the plug does have a bit of red in it lol...

the hole with the bolt in it is the one you want...

i do have a year old lambda sensor to fit,if you want to buy it...they are a smaller thread to normal ones.....it just hasnt got a plug on it...can buy 3 pin plugs easy....pm me if you want it
