Sensor behind catalytic converter

Hi all,
Could someone shed some light on the sensor behind the catalytic converter on my u42t minicab. Is it just a temp sensor or is it an o2/oxygen sensor? Cheers

 

Please fill out your signature and give us some more information. It gives us enough information to give you good advise.

And, it is most probably a thermal switch if your truck has a carburetor.

 

truck is a 1997 Mitsubishi minicab . I’ll work out how to do my signature ASAP
