Hi all

 

My left o2 sensor is reading on average 0.17v but when I rev it goes up to o.6 or so the right one is steady at 0.6 or so.

 

Do i need a new left o2 sensor?

IMO, it is better to change both O2 sensors at the same time.

Thanks buddy but do I need to change them? As in does it sound knackered?

remember seeing this might be worth a read 02

so it seems the stuck one is the shagged one.

If its not fluctuating then its not working, I personally would replace both.

Thanks mate thats really helpful.

 

It looks like I have left bank running lean and right bank running rich?

If its not fluctuating then its not working, I personally would replace both.

 

They are both fluctuating so I'm guessing they are working just fine. Although I'm a bit confused as to why the left is running lean and the right is runnning rich.

They will fluctuate very slightly even if they are bust. I would just replace the 2.

Ok thanks mate
