oxygen sensor questions..

[padrickz88]

ok so my oxygen sensor has gone to a better place.... and i need a new one, so here is the questions
1. if i was happen to get hold of a L67 oxygen sensor, would it be a direct swap? (i read somewhere that it is but id rather confirm with you guys before i go spending money)
2. roughly what would be the price of one? the supercharged and the stock replacement?

sorry if this seems like a n00b question but i couldn't find it anywhere and thought if it's a direct replacement, then why not put something better in

thanks alot

New ones stock replacement is about 30-40 bux. Theirs to different types, a single wire and a double wire. Make sure you get the correct one.

I recently had my exhaust replaced. One issue was that the oxy sensor was not fitted in the exhaust system. Should I get one fitted? I don't have any issue with power from the V6

It will not be a direct swap as you have a series 1 VN which means you'd have a 1 wire oxygen sensor. Series 2 onwards had 2 wire oxygen sensors. (VS might have been different again anyway but were atleast 2 wire).

VS have 4 wire O2 sensors so i would assume that the L67 has these also.

if you have a S1 VN you would need the single wire as mentioned above. however you can fit a 2 wire if you wish, just wire the extra wire to earth (block or chassis), should in theory give a better signal to the ecu (there is a reason they fitted 2 wire sensors to later models)

you should. you may not have lost any power but it will effect your economy

Yeah i'm using a 2 wire one in my VN which had a 1 wire one to start with. i had a brand new 2 wire one laying here which i didnt want to waste. all you have to do is wire the black wire to earth.

[padrickz88]

ahh nice will do then... thanks for the answers people

ill get my mate to get a price on a 2wire o2 sensor from his work.... thanks again...

[PREDATR]

22 wire ones are cheaper than the 1 wire ones! so i dont see the point when a 2 wire will do the job!

[Anthraxnz]

In Summation

The 2 wire ones are better than the 1 wire ones?

[PREDATR]

In theory yes. 2 wire has its own earth. 1 wire earths through the extractors / block etc.. which all heats up. heat = resistance in electronics.

In Summation

The 2 wire ones are better than the 1 wire ones?

YES. why otherwise would holden fit em if they weren't better? as i mentioned above. all sensors need a good clean earth, that way they provide the best consistant signal to the ecu. if you have poor earthing it's going to provide a erratic signal to the ecu as the resistance changes/fluctuates . this is true for any sensor fitted to the engine

Are you sure? The 1 wire o2 sensors were cheaper than the 2 wire ones at Repco, Holdens may be different I guess?

[PREDATR]

Motor traders prices i'm talking. which are genuine.

[lukas pukas]

how many oxy sensors? cause i can only find 1 on my vp

[1991_Vn2nV]

There is only 1.

[lukas pukas]

awesome, always thought there might be 2 cause of the v configuration

[immortality]

VS V6 onwards have 2
