lambda sensor

[fast5]

quick one, does anyone know how many wires lambda/o2 sensor on the F7P has, i'm assuming the R19 uses the same as a clio 16v?

Would imagine its just like a normal one with 4 wires, two for signal, two for the heater.

and iirc it's 3

 

[skini]

thanks people, would i be correct in thinking its on of the 1st bits to change as i'm gettin shite fuel ecomomy? i know there are loads of factors, like TPS etc, already changed CTS and it helped a bit, but still struggling to get more than 270miles to a full tank

do you get a hesitation in a morning for approx 30 seconds ?

 

[fast5]

no, i take it that would rule out the lambda in closed loop mode?

 

[BRUN]

its usually a clear sign that the heating element in the lambda is fooked, but doesnt mean the sensor itself isnt buggered

i think i'll chuck in a new one after reading that above thread... it'll prob pay for itself in a few days lol
