Posted a few times trying to get to bottom of why check light keeps coming on, its a lambda fault error code that is showing so replaced it with brand new Bosch universal & still after half a mile its back on, been on several forums to try get solution but so far nothing,
The new lambda is working but aint flickering it just sits at 0.3 milli volts so could it be that my 51plate motor dont like the sensor fitted & a genuine subaru one will be the solution, really cant afford to fork out £££££s on sending it to subaru garage but its looking only option

Also had problems with an universal sensor so in the end I had to buy a new Subaru genuine.

Hi Gramas

You would ideally need post a bit more info on your problem, or other wise it will just be guess work by everyone.

Have you had the ecu reset since fitting the new Lambda?

What error code are you getting for the lambda?

Do you have any other codes in the ecu re-occurring? if you do then this can cause the lambda to "flat line" and give off a constant signal.

Is your car standard?... If not have you removed any of the cats? (if you have, then which ones?)

You say that you have used a Bosh Universal Lambda.... Do you know which type was fitted?

Hi mate its a 2001 impreza 2.0 sport (model b4 bugeye) Facelift??? standard no engine mods when did ecu test i got 3 half second flashes followed by 2 quick & think that means error 32? A/F sensor,dont know which bosch uni model it was but will phone up moro for it then post it.there is a slight hick on tick over but revs dont move you can feel it through seats, slight motion. ive changed spark plugs and leads but this failed th sort it, sure its all linked

Gramas

would the light come on after mile even when u had fitted universal lambda, i take it when you bought genuine subaru lambda it solved the problem

Actually I never got a CE light but the emissions were horrible and it didn't pass "MOT". A new Subaru lambda gave perfect emissions.

Did not think the universal ones worked on newage do a search am sure have read this , when mine went on my 2002 sti i looked into this subaru want £340 for a new one ring api or a breakers and i paid £100 for a second hand one still okay 12 months later.

The Bosch universal lambda that was fitted was a 3 wire, LS02 code is 0258986502

Hi Gramas,

I'm afraid I would have to agree with earlier comments about the Universal Lambdas not working with the new age cars, but I have to admit that I am unsure about the non turbo (sport) versions, perhaps someone else could clarify the situation.

Gramas

what are classed as new age? what shape as thought mine was classic shape on 51 plate?

The classic is the 22b styley the bugeye is the fugly one.

new age there 4 wire lambdas mounted in the headers on turbo cars> i assume as he has a 3 wire its a classic on a 51. you quoted error 32 a/f sensor? Have you changed this?

Also as your reading codes from the eml flashing must be a classic

Read the first post.
A/F sensor, oxygen sensor, lambda sensor all the same.

air flow metre is not the same as oxygen sensor/ lambda sensor

the air flow metre or sensor is mounted in the inlet tract and sensing air coming into the engine

the lamda/oxygen sensor is measuring exhaust gases on the way out

Although i havent got a clue what code 32 is> long time since i had a classic

Guy's,

I believe the op missed the R off the end of A/F, he meant A/F/R sensor (Air Fuel Ratio) which is of course in the exhaust.

The Op does however has a classic car so he has an oxygen sensor fitted in his exhaust which has a failier code of 32, not an A/F/R sensor which was fitted on later cars and is much more expensive.

Gramas,

Sorry but miss read the post, you are indeed in a classic car & not a new age one, which means that a universal sensor should work, it seems strange that the light is comming on so quickly, are you sure that you have wired it up correctly?

I always thought that A/F was air/fuel sensor= lambda/oxygen sensor. Air flow sensor was MAF meter as in mass air flow meter.

Gramas

I hope ive fitted it correctly? Whats the correct wiring for it? will check in morning & post what ive connected to what

Gramas

The wires match up so not wrongly wired in but cant get clip to lock in as very tight just will not go? maybe this could be a problem?

maybe yes its not actually connected> its important to make sure you have a good connection there as any resistance in the connection may cause false readings at the ecu. Ive soldered the joints before to ensure perfect connections. its just a bit of a pain when/if you want to remove it.
