Yeah I always do my own services and buy good parts tbh but anyway eill really go over it tomorrow as got day off and take out and clean everything and check the pipes etc again and report back eith any findings if nothing then will change out the 02 sensor as sepulchrave suggested 👍

 

Be sure to let us know how you get on!

Hoping I find a bad connection or eire on the 02 sensor at least its straight forward just a pia changing that front sensor glad I have the split socket for it lol.

I always chop the wire off the one I'm replacing so I can use a proper deep socket because the split sockets are pants for removing seized sensors.

Good idea will do that 👍 

 

Ok so done a rescan and had a check under the bonnet but I found a sub section on my scanner and its throwing up 3 codes these are

p0130

p1176 o2 sensor correct behind catalyst B1 limit attained

p0171 system running lean

Seems more to this than I thought any ideas please guys.

Thanks in advance.

Not really, it's still all pointing at the pre-cat lambda probe.

 

If anything it's confirmation!

OK thanks mate I'm going to order one now thanks for all your advice 👍

If it's any consolation I have to fit a new one on my 2.0 every two years just to get it through the MOT, it's because the engine core is so ancient, I guess yours is a 1.4 MPI so it's no surprise to me, both our engines barely met Euro 3 emissions when brand new!

Yeah and typically my mot is due in 2 weeks so im scrabbling to fix this issue always the way it seems lol.

Replace the sensor, then clear all the codes and go for an hours drive.

I mean, I'd recommend that he "gies it laldy" as well. Clear any other crap out as a result.

The links sepulchrave put up also have the leak side I forget to put, exhaust, the blow to the hiss of inlet, a spray around with carb cleaner or other may highlight a leak (gasket, joints (i don't know what you have there).

 

Only other thing as highlight in links is computer wobbles.

 

I'm not keen on committing to replacement by cutting the wires, just in case some sort of clean up can be done, but if the sensor's low cost then the hassle might not be worth it.

 

What make of sensor is fitted now?

 

For future reference, if you didn't already know, an MoT can be done up to one calendar month before the expiry date and still keep preserving the anniversary of the expiry date - but if it fails you're without MoT until you can pas a retest.  As long as you don't mind losing the months you could have the test months before to move it to a more convenient (warmer, lighter) time of the year.

You obviously haven't had to remove a lambda probe that's welded itself into the exhaust system before.

 

Snip the wire, use a deep 22mm impact socket on a long bar and replace the sensor, tightening it into place with a ring spanner or a split socket.

 

You can't successfully clean the old one because the heater element has usually failed rendering the old probe useless.

Yeah I get that mate point is it won't pass the mot eith this issue the emissions will be in the crapper until its fixed and I'm not sure what make is in atm I'm trying to find somewhere uk with good delivery but struggling to find one atm 

I had a good spray about eith carbon cleaner but no leaks showed up snd the revs never changed so no leak I think I'm going to swop out the sensor as soon as I can find one.

You can buy NGK, Beru, Denso parts as well as Bosch, Delphi etc.

 

Expect to pay about £55, any more is excessive.

 

There are many, these are generic parts with custom wiring and plugs for the specific application.

No lambdas on very old British Leyland cars but very occasionally there's an odd dusting of rust on them and their fittings. 🙂

 

I've no doubt getting such out will be "fun" and stock levels of time and/or patience can often be out of stock, my lot of can-be-arsed is often on back order.

 

But you can't know for sure, despite the possible odds, if the probe has actually failed, it could be tested before removing or cutting of wires.

 

The hard work is getting it out so I can see as I put before the saving in hassle just to replace it if it's not considered expensive but IIRC this one's only been in two years of low mileage and they can often come pre-coated with anti-seize.

 

With parts you can often get different brand labels put on the same units and a brand that makes or buys in good parts x may not make so good part y, I've no idea of the service like of a lambda sensor but I'd hope for more than two- years of low mileage.

It's fifty quid and it'll take ten minutes, I'm not sure how you value time but I dislike wasting mine, especially at MOT time.

Stewartasb, sorry missed your posts, I was thinking of next year's MoT for you and myself as I left the Fabia so late at his year, day before, and ended up with a very distressing "distress purchase".

 

No sucks or blows is good in one way and at least you know at next to no cost.

£50's worth a lot more outside of the south. 😉

 

If it's only 10-minutes work to replace then it's only a little longer to check it, remove it, clean it, put it back in, my concern is that it doesn't become another £50 and 10 minutes that is unnecessary or doesn't resolve the issue if which case it hasn't saved time and it's not just £50 but an additional £50.  I've spent my fair share with the parts cannon and more than that in helping keep the world economy turning with my car costs.

 

There's a good chance it's the lambda and you'll be able to rightly say you said so - but it's not certain, yet any way.

 

I did have a mid year mot date but had that pesky 6 month extension in covid so now it's winter time and thanks wino I've got it ordered now mate. Thanks all again and hopefully this resolves the issue I popped out in it today and it was drinking fuel like an audi r8 on steroids  so might just leave it parked up till new sensor comes trouble I have is the missus likes to keep borrowing my other motor 😡

If you seek certainty then good luck with that, I live in a probabilistic universe.
