rb25det series II o2 sensor - where to get?

[paulr33]

hi guys,

i think my o2 sensor is dead. my fuel economy sucks (250k's ish on a full tank) and my apexi pen timer doesn't read the o2 sensor value at all. my fuel economy has always been like this so i thought it was normal but reading some threads and doing some searching and it appears my o2 sensor is dead. i wasnt sure if the apexi pen timer was working properly cos it has never read the o2 value always displays "---" but ive checked the wring and it seems fine.

also when i had a dyno run on the dyno bbq day i got 141rwkw and it was running very rich and had some black smoke puff out

does anyone know where to get a new / 2nd hand o2 sensor from? how much?

any help would be great, thanks

Yea you can buy new ones for like ummmm around 150 i think but dont quote me! You can get second hand ones easily from workshops around the place usually like 80 or so not that expensive just make sure its ok before you buy it!

I remember reading here somewhere that an EL falcon sensor is the same (bosch?) and costs about $70 as opposed to the $150+ nissan genuine item. You have to splice the wires in tho. do a search and check it out.

dunno but the 33 ones have 3 wires, im looking at my old one right now, I got a second hand one for like $80 from a workshop up here i know...check around you'll find one easy, they have heaps of them lying around!

Just put it the same way the old one was ..

[paulr33]

it looks like it doesnt have a plug so i can't rejust remove the old and put the new one in. ill need some way to match the wires. will check tonight when i get home

[paulr33]

ok the wires being matched is easy but getting the actual sensor out is a bitch. theres hardly any room to get any tools in there

[gtstcruiser67]

There's a socket specific for removing sensor's.It has a groove up the side of it to allow for the wiring. An auto electrician or mechanic should be able to help out.

[paulr33]

yeah i was thinking of doing that, plus my radiator overflow pipe snapped off somehow and that needs to be replaced, looks likes its been glued previoulsy

If you want to be anal raped HARDDD...

Get a 300zx sensor like, comes with a V. LONG tether for the funny VG30 block, standard Nissan plug. I got 400km out of tank and THIS INCLUDED high speed, high rpm. tuning so....

Oh well... live and learn.

[paulr33]

nah its cool, ive already got a new o2 sensor just a bitch to fit and ive got really shit tools here. will organise with a mechanic to fit it for me and swap for a new radiator

[paulr33]

hi all, have gotten the o2 sensor fitted and done. the ford el one did it fine. the apexi timer now shows the o2 value and it fluctates from 0.30 to 0.20 and 0.10 is this correct? upon de-acceration it goes to 0.02 and 0.01. however if i goto a/f it shows "---" still. am i missing something?

will update when i check my fuel consumption

[Sumo]

yeah mate, let us know how it goes.

[paulr33]

the light for o2 goes from green to orange to red mainly at green when idle and orange when midrange accel and occasionally a spot of red if i stick it. ive only seen the highest about 0.40 shouldn't it be up near 0.60 ? the range as far as i know was 1.00 to 0.00 correct?

0.50 would be midrrange?

as in not lean and not rich

[wilch]

how's the fuel economy now?
