i think the vauxhall part no. i need is 25133396- 3 wire sensor however according to vauxhall this part is out of service now!!
and to replace it is a 1 wire sensor- part no. 25133607 or 25133396
will this have any affect on my car, by going from a 3 wire sensor to 1????
i have read a old post about it, and from what i can remmber it did not work properly!! but i cant remmeber it properly??
my chasis no. is VSX000073P4317076 if that helps

you need the 3 wire sensor as you have a heating circuit in the sensor

lambda sensors work when there hot, single wire sensors use the exhaust gases to heat them up to temp beofre they work.
3 wire sensors have a heating element in them hence the extra two wires so it heats up in a minute or so. putting a single wire sensor in should still make it work but if it had a three wire sensor you should really put one back in.

ok the new sensor made the car idle very badly with revs randomnly dropping and rising
so i diconnected the 2 white heater wires and left the 1 black wire and the car was fine, no ecu/eml light came on at all and it drove fine ???
will the sensor still work fine and not affect the car in any way for the emmisions on the MOT??

its will fail on the m.o.t. because sensor will be diconnected will not get a reading
I am sure the black wire is ground, as the lambda sensor is power by heat of the exhuast manifold

hmmm would this not bring up a eml light then, if the sensor was detected to be disconnected and or not working??
and i thought the 2 white wires are JUST for the heating element in the senor to warm it up?? which with out is not a big deal as the exhaust gases will warm it up in just few seconds!!
PLUS if i got the sensor from vauxhall, it would have been a 1 wire sensor! as it has changed??

*UPDATE*
ok the eml light did come up and flashed code 23 - no voltage or open circuit in lambda!
however when i took to MOT the lambda reading was ok BUT
the car was smoking more then normal because i just topped up the oil, and maybe a bit too much so he told me too let it cool down and check oil level!!!
what are the limits for each of the emmisions readings???
and would my car fail any of them if its smoking???

yes thats what i thought mate??
ive really had enough of my car and mot garage! 
spent so much on it this month for mot and still dont pass!
what are the limits for the emmsions readings for it too pass??
all i can remember is that the lambda was about 0.82 and co/carbon i think about 1.12

co below 0.30
hc below 200ppm
lambda reading between 0.970 - 1.030
can fail on excessive smoke

i remember the lambda reached lowest point of 0.82 when he revved it
but the co i think it was either 1.12 or 0.12, im not sure, what sounds more realistic????
and would the actual burning of oil/smoke cause the emmisions to be higher in any way, and if so which reading??

oil burning shouldnt affect the emissions, if it failed on co then it 1.12 is realistic as 0.12 would pass.

thats the thing i dunno if the emmsions were ok or not or if he jus failed me again because of the excessive smoke
think my mot mechanic was just being a moody bum, slightest problem i have each year and he fails me, even on things that other people say it should have passed on!!
if it was 1.12, is that fairly out?? and would it need new CAT??

could be the cat, could be something else, 1.12 is quite high, yesterday we had a car in that was over 10% tho lol
try another mot garage

the CAT is new however, i installed it at last years MOT! cant be damaged already!
car does seem to be drinking a lot of oil lately though!!
topped it up too much the other day, so i had to drain some of it out, not sure how much i took back out but now its under minimum mark and ive only driven it about 50 miles! but it is not making the tappy noise yet which is weird as it usually does at this point!!!
i also used bottle of wyns smoke stop oil addctive, this stuff usually stops the smoking dead after a few miles, but its still smoking!!
retest is on Tuesday morning!!
any advice for the oil/smoking??
i was hoping if i just drive it around a bit more till then, the new oil and oil additive will have settled in better, as i notice when i put fresh oil in the car it does smoke for a lilttle while??
