Cant remember the name now, but it was about £40. my car is a 99 Type R and a CEL is a "Check Engine Light" so I have just ordered one from Camskill, hope this one will work as it should.

 

Will you report back when you receive it?

I think i'm going to try the one at £60. The guy said you get 12 months warranty, so if I experience problems similar to you, i'll ring the people up and demand a refund.

Don't think mine has a CEL light (being a '95) think it's just a red ENGINE sign.

 

I will report in when it arrives, wont take long to fit

 

If it's correct to your vehicle spec, It should have a long flat block connector with all the connector pins in a row, not a conventional square type block connector.

 

Heres a really idiots question for ya, does the car still have a lambda sensor if it has a decatted downpipe?

My 95 wrx is using a bucket load more fuel that it used to but am due to get a decat downpipe on soon, would this help and stopped the need for buying a new lambda sensor?

I know im stupid

 

Yup fraid so, a Lambda Sensor is essential, wether or not you have a cat fitted.

 

You can see in most decent pictures, the hole where the lambda sensor sits - even in a decat pipe... See it right near the top end...

How do you know that?

 

because your car should have the sensor in the headers etc..

Cheers

 

I've justhada look at that 'Camskill' sensor posted in this thread, and it too has the square connector block:




Seen as my sensor is in the headers, can anyone tell me where it plugs/unplugs - so I can double check the connector type before ordering?

An engine bay pic with an arrow would be ideal.

I only ask, as I work office hours, so it'll have to wait till weekend (because it's dark when i'm not working) if i'm to crawl under the car and trace it back by myself.

 

you need to alter the wiring for either the camskill one or the universal one as the lead (longer) and plug are different on your car..

Simon

 

Any ideas which wires goto which?

 

Sorry Bro but your wrong.

The Lambda is n the Header, I followed the wire up and you can see it in this picture - it's got yellow tape round near the end of the wire:




Her's a closer shot:




You do have a point about making sure the wiring is long enough though...

 

On my 93 wrx I had the one that is fitted to the headers with a sqare plug like yours, however when I fitted a decat downpipe I relocated the lambda sensor to the downpipe.

 

does it matter if the sensor is in the header or the downpipe?? I replaced mine not so long ago, obv in the headers, but it made no difference at th mot, still maxed out the emissions machine!!!! does it need a cat for the emissions generally???
sorry for the slight hijack, it is kinda on topic!!! lol

 

no different just lasts long in the downpipe.

if the garage does the correct test for the earlier car then it is possible to get through without a cat but they have tightenned the emissions right up

 

Where does the sensor from the headers plug into the wiring loom, i have just fitted my headers but i cant find where the plug connects back under the bonnet?? Doh

Cheers
Chris

 

assuming minty this is on you 98 with 96 engine then the plug will be under the tmic by the bulk head as you using the 98 loom.. therefore needs to go in the downpipe

 

How confusing i guess you got my recent PM then. Cheers

I have already got the one from the down pipe plugged in and i think it's there too, so i guess the one in the headers is a backup/spare

Cheers
Minty.

 

yes but remembered from you posting about it

I will reply a bit later to pm as just off out

would be worth removing and putting a bung in as the sensor will clog without the heater wiring connected, then keep it as a spare.

 

cool, i will do cheers.

no worries on the reply, just let me know if you need it sooner.

Cheers
Chris.

 

Guys - i'm confused.

On Friday night I connected the two black connectors behind the dash, and turned the ignition to 'On' in the hope of seeing the error code saying the Lambda sensor was faulty.

However, the Check Engine Light flashed steadily, indicating no error.

I'm confused, do you think it is my Lambda that's faulty or not? Should I bother replacing it or not, bearing in mind the mechanic said mine was 'Lazy' when cold.

 

very very rare for the ecu to see a faulty lambda as the sensor range is 0 to 1volt all of which is valid.. therefore unlikely for it to log an error

Simon

 

Definitly worth replacing it then? In your opinion, is there something else that could be causing this rough idle, an inconsistent idle, when cold? AND increased MPG?

 

Anyone?

 

you cant really go wrong by replacing the sensor, at least you know then its good. If it doesnt change your issues then look at something else.

 

That's what i'm saying though, I don't really have the money to waste.
I'm skint at the minute and can't afford the sensor really.

I don't have any credit cards or anything, so have to make the money i've got last.

If there's something else, boost solenoid or something, that could be causing these symptoms?

Just need an expert to say, I know it's difficult without seeing the car, if it's the Lambda that needs replacing. Would resetting the ECU by connecting the green connectors behind the dash help?

 

Tried PM'ing you but your inbox is full. This is my reply to the questions you asked me.

My car is a '96 WRX with an STI engine. I have an Apexi PowerFC ecu and commander so I can check the voltages on the sensors such as the Lambda,that's how I managed to find the fault.

I don't think a failed Lambda sensor will give an error code but i'm not 100% sure about that.

I got my universal Lambda from here: Just Lambda, Suppliers of Bosch and NTK lambda sensors including zirconia and titania sensors by post

It's the LS02 that you want,second one down on the list I think.

I think you can get a Bosch LS02 sensor cheaper from Brown Brothers or similar.

Hope this helps you.

Simon.

 

Just thought I’d give you people interested an update on my lambda sensor predicament…

I bit the bullet and rang a local parts company, Andrew Page. Gave the kind gentleman my reg and he said “The sensor we have listed for that car is £79.60 including VAT, do you want me to order it in? It’ll be here Friday.” So I picked it up Saturday.

Opened the box, had a look at the sensor and it’s blatant the wires aren’t long enough. I rang back the idiot that’d sold me this ‘Direct Replacement’ lambda and he said “Oh…”. I asked if I cut the wires and extended them, would it invalidate the warranty. Ofcourse it will I’m afraid, was the reply.

So now…. I’m trying to get them to find out the correct part. They do stock a Bosh universal one, that I’ve been told from members on here will fit no problems, and guess what, it’s cheaper than the supposed ‘Direct Fit’!

Can anyone on here who’s replaced the Lambda sensor that’s in the headers (not the down pipe), please tell me which sensor you used and how much it cost?
