I was just about to fit a lambda link and i noticed that there isn't a sensor. I was under the impression that all Scoobs had these and that they are positioned just behind the Turbo on the top of the downpipe but i have a bolt in its place.

My cars and MY94 WRX JDM.

Are all scoobs surposed to have them and does it matter if it doesn't?

Thanks for any info.

Dave

ps. Of out for the day so pick messages up tonight.

 

Yours is in the headers, if you look down the drivers side of you engine you will see it.
The wire runs up the head and plugs in just by the power steering pump.
Rob

p.s. take the connections at the ECU though.

 

P.P.s

All JDM cars up to 96 have the lambda in the headers/manifold

Rob

 

Cheers Rob, Ill take a look at the weekend

Yes Dave, it's like what Rob said, MY96 or Ver 2's Lambda sensor is located in the headers. If I recall correctly, it's on the driver side (assuming RHD) under the Air cleaner thereabouts.

I have fitted a number of these from MY96 to MY00 and you don't see Subaru adopting the same method like that did with MY96 or earlier and for good reasons. The temps in the manifold are said to run much hotter than exiting gases in the downpipe. If you're running an aftermarket (downpipe) one, there would already be plug for the lambda sensor. I suggest you have it relocated to the downpipe.

Is relocating a straight forward swap, or would i need to rewire anything.

Dave

 

Whether or not you need to rewire depends on the make of Lambda sensor from Subaru dealership. I have come across two different designs kinds: one with short wires while the other has longer wires intended for use in your type of vehicle. From personal experience, I've found the wire pins to be different and I recall switching the color codes myself so it's not a difficult thing to accomplish. You would also need a bolt to ensure a good seal on the manifold after you've relocated to the downpipe. All the best.

 

Cheers, Ill have to take a better look at the weekend.

Thanks
Dave

 

I'm going to have a look at fitting this tonight as ill be home from work about 4.

Could someone tell me which wire on the ECU to connect the lambdalink to.

Cheers

 

Regarding moving the sensor, your original one will reach the downpipe although it will be tight, I've done this on both my cars, a MY95 WRX and a MY94 WRX wagon.

If you already have an aftermarket downpipe then you can use the bung in the dp to block off the headers.

If however you move it when you also purchase a dp (most do not have the bung) then the thread is M18 x 1.5, which is the same as a pinto spark plug.

 

cheers, Ill have a go at a straight swop over,

Anyone an info on fitting the lambdalink.

 

DO a search for ecu pin outs, it will give you a link to www.saxonfields.freeserve.com
or something like that, find the ecu pin outs and connect the LL wire to the lambda signal wire, earth the LL to the ecu frame for best results..

Rob

 

Look HERE and HERE Plug B43 terminal 6

Hi, i spoke to someone about this at the Ace Cafe last night. He was saying that it should always be connected straight to the Lambda sensor and earthed to the engine blocl for best results.

Whats the Difference in the way it performs?

 

Sorry to hijack this thread.I've just had my garage put an after market down pipe onto MY94 WRX JDM and when they removed my cat they said that they could not get the lamba sensor out (i seen this and it was stuck solid).I have ordered a lamba sensor to replace this.My question is the sensor was after the cat on a long wire which was protected by a wire sheath, is this the lamba sensor or not??

Cheers
Brian

 

no, it's the cat temp sensor

 

Can the car run ok without the cat temp sensor Roojai??

 

Yes.
