O2. Sensor again

Previously I was not getting a reading so I decided to take it out...

Right so managed to get it out gave it a clean. Notice the wire was broken too! The red one. Soldered it up put it back together.

and now am getting a reading (using a Nissan software called tecu)

Now I'm driving my car it feels worser there is no top end power after 5500rpm!

Sensor voltage is hard to read as there is a delay. It goes up and down though..

What voltage reading should I get at idle?

My doubts are..
. Not tightened the sensor hard enough,
the washer needs replacing,
need to set my boost controller again(i'm not getting more than 0.9 used to get 1.1)
Sensor is fcuked

Red wire damaged!!

This link gives you detail how to check it

Brilliant Spike. The information is really useful. But is z32 our car?

Also says we have two sensors?

No z32 is off a 300zx .... i think he means testing wise or method will be the same ..

Ahh yeh got you. Cheers guys

Mines acting very similar, my 02 sensor looks spot on and the wires are intact, I don't get any power and it struggles to rev to 5k

Is your 02 sensor working? I am in power till 5k then its pants

Turns out it was a boost leak for elliots car mate but had similar thing to you ...
