I have a Denso one fitted to mine that looks the same based upon the part numbers. I paid nearer the Import Car Parts price though. Denso is the factory spec equipment only difference is you can get it with a subaru parts label for a lot more cash

Ricky, you cannot turn off the precat sensor even running a decat as this is how you measure the stoich point whilst running off boost. The second lambda sensor is a check sensor so can be disabled as this may throw a fault code if you run a decat.

 

Great thanks for clearing that up mate. Will order it later and get my hands dirty at the weekend

 

Contact this company,this company selling Denso Lambda sensor for good money

Thanks Jura, going to order one from them later today

 

If you need a big spanner give me a shout and I'll sort Ricky's number out for you

I have one in the garage if he's not available

 

Thanks Jon

 

Just go from the top to do it mate.


Peel back the arch lining and hey presto.


Steve

 

There's a small panel on the drivers side arch liner that you remove for easier access as it is usually in the headers rather than the downpipe on a bug, unless it's been moved and rescaled when the exhaust was fitted

 

Thanks for the "how to" guide guys it sounds more awkward than difficult. I didn't get around to ordering it today so will sort it tomorrow for a Saturday delivery. Fingers crossed the weather stays dry.

 

Weatherman says 24 degrees on Saturday

Fiddly is right, difficult it certainly isn't

 

hopefully it won't take much longer than an hour as long as I can get the old one out

WD40 and brut force will be the order of the day me thinks

I have found a 19" spanner so far, is the enough room for an adjustable spanner?

 

I recall buying a large ring spanner because the adjustable wouldn't fit

 

I have just read a how to guide with pics and it is pretty tight down there so you are right about the adjustable not fitting. It also said that a 22mm spanner is needed to remove it.

 

22, 24, what's 2mm between friends

If you need one I have the right size because I've done mine

 

I thought that was the one Martin was on about. It went on the blink on mine a couple of months ago.

 

Please refer to post 35

 

 

lol

 

Sensor all ordered should be here tomorrow

Will the CEL light go off once I fit the new sensor?

 

It will eventually once the fault has gone away - on vauxhalls you have to restart the car three times. It would probably be better to reset it with a reader if you can get access to one again.

 

Great, will see how it goes next week and if no joy give brownpantsracing a shout

 

Question: what effect will the sensor in the headers going kaput have, apart from a fault code, and the same question for the sensor in the second cat?

 

The first is used as a part of the closed loop with the MAF to regulate the fuel mixture off boost to keep the ratio at the stoich level (14.7:1 - air:fuel). Without this car can run lean or rich.

The second sensor is a check sensor to confirm the emissions coming out of the CAT and will identify if the CAT is on it's way out. For cars with a decat any codes relating to the second sensor can be disabled

 

Martin, sorry to hijack here.

Jon, in theory then, as I have a decat I can have the check sensor o/p disabled with no effect? Also, and more importantly, as i have the PSI3 now, should I see AFR at idle as you have indicated above, 14.7:1? Would any wildly lower or higher figure indicate the sensor at the headers is on its way to the bin?

 

Think mine is running rich because of the sensors progressive failure, used a quarter of a tank of fuel just getting to uxbridge and back when I met Steve the other night and that was driving conservitavley!!!

 

You can cancel the codes for the check sensor - I have without any ill effect.

On the PSI3 you should see a lambda reading of 0.97-1 at idle (and arguably whilst driving off-boost) but nothing much beyond that - those figures also represent the tolerance required for an MOT pass. The readings will be very different from those under either boost conditions (it will run richer) or whilst engine breaking (it will run lean).

 

That is quite normal as running lean is more dangerous that running rich because of the likelihood of det, limp mode will add a 'touch' more fuel as a safety measure to avoid det.

 

Thats reassuring to know. Will post up how I get on with it.

 

If you need to remove light again after fitting mate let me know.


Steve

 

Thanks Steve will do, you might even be able to get your car out this time
