Oxygen sensor - collar around it??

silly question, when you start TS, did you open the drop down menu at the top of the screen: Setup/VIM select - and choose your X-horse VCM? You have to do that before trying to connect.

Yes, Torque should show Fuel Trim data (as well as A/F and O2 sensor data).

 

1. Yep, I use the drop-down menu for Setup/VIN select. Techsteam remains elusive, despite all the time I've put into trying to get it to work.
2. Good to know Torque should read Fuel Trim Data & A/F. I changed Bank 1, Sensor 2 (02) a while back thanks to Torque specifying the ODBII code for it. Easy to change (compared to Bank 1, Senor 1).
Thanks again!

Carid has a thin walled socket for 13++, and a Denso A/F sensor for 136++, or the TRQ version for much less.
