Right so as my Lamdba has not been working for aaaages now, I went and got myself a new one, but not a normal one, got the idea from 'The Dash'.
Pretty impressive to note I have gotten 400+ miles from a tank without a working lamdba :stuart:
The stock sensor earths itself through the manifold and the grounding strap that is normally present at the end of the downpipe, now most people upgrade to stainless manifold and rarely put the the grounding strap back on.
Stainless is a shit conductor so the lambda is basically not earthed, now the new sensor I have has a separate wire for an earth
Heres what I have;
1 scissor jack achieves this :clown:
Removed the old sensor, possibly the 14yo original
With its 3 wires 2 Heater (White) and 1 signal (Black)
The New sensor
Comes with everything you need
4 Wires
1 Black - Signal
2 White - Heater
1 Grey - Earth
(Kinda missed a few pictures)
Old vs New
The new connection and the extra wire
Finished with a ring terminal and some heat shrink
With the new lambda installed, the wires sat right by the earthing points on the back of the inlet so I have earthed it there
Taking the car out shortly so will see how it is now
