Thats definatly the one i bought.

I would buy from them again though because they are some much cheaper than other suppliers.

Although as i said before mine wasn't NTK or Denso as they say it could be at the bottom of this page

http://www.gendan.co.uk/article_11.html

Mine must of been the O.E Branded one maybe MAFFA got a different one to me.

Anyway at £29.95 its worth another try.

EDITED TO SAY
---------------

As per previous post on page 1

Lambda was not at fault. I am currently running another universal lambda from Gendan with no issues.

Definately

I didn't look at the make on mine but I guess you could be right. Either that or you just got unlucky and got a dud?

You will need a 'Zirconia' NOT a 'Titania'. Titania have reference in and out signals and sometimes combined heater/signal wires. Which you do not want.

You need Something like this (I have the 4-wire):

3-Wire

Colour Connection
Black - Signal
White - Heater
White - Heater 11983

Universal Zirconia Sensor
Output 0.1 to 0.9 Volt

4-Wire

Colour Connection
Black - Signal
Grey - Earth
White - Heater
White - Heater 11984

Universal Zirconia Sensor
Output 0.1 to 0.9 Volt

see Just Lambda for UK lambda sensor sales
I went for 1 x 3WU (3 Wire Universal Sensor (NTK))
£41.12 inc VAT and UK First Class Post


Prey it fixes my rich running problem!!!

Hi Folks,
I got one of the 3 wire ones from gendan and gave it to the MOT place to fit. (It had failed the MOT on lambda readings). They fitted the new one but although better, still failed. I took the car away to try and get it sorted myself. What they did was rather than chop the end off the sensor wire to fit the car wiring, they chopped of the plug of the car wiring to fit the new sensor. Still, problem is the lambda light is on, which it never had been before, so i tried swapping the wires around.
The sensor has two white and a black wire, and the car has a red/green and blue/black.
As soon as I disconnected the wire, the light went out, but I want to make sure I've done it right so it doesn't fail the retest.
So, what Im trying to ask is, which wire goes where???
Thanks folks,
Bod

What model and year is the car?

You should have 3 wires coming from the loom of the car, what colours are they?

Hi Craig,
Its a 94 wrx. There are only two wires from the car, one red/green and one blue/black.
Does that make any sense?
Cheers

The Lambda sensor is before the turbo on your model, in the headers/up-pipe (exhaust manifold) are you sure you have the right sensor/sensor wires.

It's just behind the turbo, under the clutch master cylinder.
I dont know what the old wires were as I left that for the garage to get rid of. Doh!
The red/green and blue/black are where they connected the new sensor to, so I hope thats where the old one was connected.

It sounds like you have removed the "cat on fire" sensor not the lambda.

Check your headers/exhaust manifold behind the drivers side wheel and you should see the lambda.

IIRC when you find the lambda sensor (the plug should be above the drivers side head) you should have 3 wires - red, black and white. White is the signal.

On your lamda sensor the single black wire is the signal, the two white are the power - connect one to red, the other to black.

These will all have them

HDC SUBARU

ScoobyTeknix

Grade A

Do a search on eBay for "(subaru,Impreza) breaking" and you will find loads of others.

Let me know what colours the wires are from your loom going to the lambda and i'll tell you how to wire your new lambda up

You dont need a cat sensor, just leave it unplugged and the light will stay out.

Thanks Jay,
I'll go change it in a minute. Just need to sort a cat sensor now, and fingers crossed for the MOT!
Cheers again

This is correct

Dont forget to reset the ECU after you have done it

Just make sure you have the right plug!

Trace the loom back from the lambda sensor, as Heple says its in the headers pre turbo on the drivers side, its best to find it by looking underneath the car and you will see it sticking out from a heatshield.

Good Look Bod

I'd have a quiet word with the garage that attempted to change the Lambda 1st time round

Now ...... Back to work
