02 sensor fault

can an air leak cause consult to flag up an 02 sensor?

 

borrowed consult off work and driving along it falgs up intermitently with a 02 error (S1?)

 

checked the wires and conectors all good, i know i've got a few major leaks as z1 didn't deliver ,my silcon in time so its got the old craked pipes on at the mo...

 

any one got any thought?

    Not sure on a zed but on modern cars it can for sure - if there is an airleak in the system then the O2 sensor can lean right out so it doesnt switch, the ECU sees this & flags an O2 sensor fault.

     

    As said - not sure if the zed ECU detects fault in this way or if it is just looking at the circuit of the O2 sensor as it is not as sophisticated as later OBD cars.

     

    Worth looking into however if you suspect an airleak! :)
