3s-gte o2 sensor wire help

[BlitzRacing]

Hi guys,
Need some urgent help.
This is from my mr2, but im sure it applies to most 3sgte motors.

I have a burnt out o2 sensor wire, without plugs.

I am needing to know if the wire I am pointing at in the picture is for the o2 sensor.

BTW My o2 sensor has only 1 wire.. So i am presuming this to be it.. any confirmation? anyone with a mr2 and can confirm?

Thanks a million..

is this an Mr2 motor or a gt4 ? edit fool re read i would think it would be

where is the o2 located ? is the other end on the o2 or is it gooonez
i cant check now i just relised as my mr2 loom is goonsiks

sorry i didnt give a more definitive response

get a multi-meter and check continuity between the wire indicated above and the O2 connection in the diagnostic port - should be close to 0 ohms between them if the wire is the O2 sensor.

^^ thanks

Im fairly new to toyata... but how do I actually use the diagnostic port? . is there a pin for the o2 in there? or read the cels for diagnostics?

Ill might just check for connectivity to the ecu's ox pin.. thanks for the idea...!
