@jay see if you download NDS I for android or for windows you will be able to check out codes etc you should also be able to check out the readings from the o2 sensor as well. I have been using ndsII for a while for checking stuff and it's great to use. The android app will only read ECU . The windows version reads ECU and TCM
Only thing you will need is a consult I plug either usb for windows or bluetooth for android.
Maybe a member around you has one to borrow?
Alternatively you can get an adapter from consult to obdii style as well
