Got CEL on again today, was originally diagnosed as O2 Sensor, we tried a reset and light stayed off for a week. So time to replace the sensor I think. Anyone know if I will have a 3 wire or a 4 wire sensor as Ive come across this site.
Lambda Sensors - Cats Direct and not sure which to try.

Thanks

Chris

Let me know what you find out. I am in the process of trying to find a Oxygen sensor for a Y Fozzie. Only finding conflicting info the web re appropriate part numbers and if a universal lambda is available for and EJ205 engine.

just done some more reading on here and seen it mentioned a few times that only genuine ones work on newage cars??
Can anyone confirm that they have used a 4 wire universal o2 sensor on a newage? (the one in the headers). And did it work?

Hi Chris,

is it a sensor failure or is it just whinging 'cos you've a non-standard (de-catted ?) exhaust ?

Just asking as mine used to throw a CEL, but stopped after the re-map.

Sorry if off track, but I thought I'd ask....

Not sure to be honest. When Chy at penine subaru read the code he said the sensor was reading correctly, and to try a reset and see how it goes.

He did recommend a new one if it flashed up again though. If a Universal one isnt suitable I may have to bite the bullet and fork out dealer prices

Gonna check all the wiring etc tomorrow, hopefully something simple like a damaged wire

I've just been thru all this stuff recently and ended up getting one from Jap Performance Parts : Home. It's a genuine Subaru part from a wrecked car and was £75. Part No: 22641AA042
It's 4 wire and as said before the universal ones appear not to work with Newage ECU.
Camskill also do one for £150 - Denso one.

Hope this helps! My error code was P0031 iirc and the light went off as soon as the replacement one was plugged in.

Thanks alot mate thats a great help, was hoping to avoid the rip off dealer prices.

So if I read it correctly you didnt require your ecu resetting afterwards?

Thanks again

pmacFTO

nope - light went off as soon as we started the car up...it had been coming on then going off again regularly but then eventually stayed on permanently - I think it does 3 cycles of starting up, driving turning off as a diagnostic then if the error still exists it stays on all the time.

The code seemed to clear itself but will still be recorded in the ECU as a historical error - I believe that can be cleared too but since the car is running fine (and less rich!) I am not too worried

Chris.. Just for info could you post the CEL code you have

Is it P0420 or P0031 as I'm a bit confused.

didnt want to jump on someone elses post but has anyone ever had blue sludge in the coolant overflow im pretty sure its rusty pipes or something i dont think it is hg cause levels fine no coolant in oil, no exhaust smoke or fumes please help. i.e my pipes are vety rusty and the old owner didnt drive it much could this be corrosion in the pipes. sorry for jumping on this thread.

chrisUK300

Not sure on the exact code but it was one of the codes relating to O2 sensor Bank 1 Sensor 1.

Definately wasnt P0420 which i believe is Catalyst Efficiency??

pk4rney

anybody?

Have found an Italian company that manufactures various car parts and they seem to have the near identical part i require.

http://www.facet.it/db_comp/catalogo/catalogo.asp

Did a search using subaru part number 22690AA501 and came back with 10.7805 as the replacement.

Will try to find a retailer here in the UK. Just to compare prices for the oxygen sensor that i require.

would a remap sort it out, mine did the same when I changed the exhaust system

Not sure but Ill soon find out, got a 2nd hand lambda sensor on its way to me, if that doesnt cure it then I may have to push the remap further up my list of things to do

NO ! slippery slope warning....

I replaced my o2 sensor on my bugeye, part no.22641AA042, the Denso part no. is 2349011. I got mine from rock auto in the states, $142 which at the time worked out at £78 inc delivery plus £20 import tax, still under £100 though. I think camskill is the cheapest if you want to buy in th uk at £150.

It's impossible to map out a faulty front sensor.......in any case it's needed by the ECU for open loop fuelling

The fault is usually logged by the ECU as a heating circuit. Faults associated with misfires on Bugeyes may be spurious, particularly the 2001 bugeye with the radio mast in the a-pillar.

Misfire CELS also caused by faulty NPS switches on early bugeye's too

It pays to make sure that it is the front lambda sensor playing up on this model !!

Definately is the front sensor playing up. Got a 2nd hand one on its way to me which I got at a bargain price of £12 .
All wiring has been checked today from ECU to sensor, voltages and resitance readings where fine and all connections cleaned as a precaution.

Can see faulty sensor as only explanation unless someone has any different suggestions?

Sorry to bring up an old thread, Did you sensor fix the prob?
I think my front sensor is playing up to but ive got irregular idle (Hunting)with it, was yours the same?

I also have the same prob on my 02 bugeye wrx.
Im not to sure if its the front sensor or the sensor in the midpipe causing my problems. Can some one please tell me????

The exhaust is fully de-cated.

Can anyone tell me if I can re-route my lambda sensor cables without upsetting the ecu! My import has a 27" cable and the new ones only have ones about 15"
