Powertrain / Under The Hood • Torque PRO and 02 sensors

Replaced all 4 02s a few months back with Bosch upstream and NTK sensors Downstream.

I changed these in an attempt to hopefully gain mileage, hasn't happened still about 16.0 MPG down from 18.3 a few years ago.

The patient is my 200K old 2013 EB Limited.

Oddly and frustratingly, my Torque PRO app does not show any reading for 02B2S1EQ (Oxygen sensor Bank 2 sensor 1) the upstream fuel control sensor nor the voltage output.

Now I'm running an PID upgrade I found for a Ford EB truck, this gave me access to some extra guages not available with the standard Flex, like Tire Pressure, a nice addition.

I've never been able to see any output for Bank 2 upstream 02. I'm suspecting maybe I have a broken wire in the loom. If this is the case, it would possibly explain the fuel mileage drop (not being able to properly control fuel output on Bank 2) and the no gauge reading issue.

Has anyone else experienced a non-reading 02 gauge in Torque?

Then the next question is chasing down the pin-out for the 02 sensor in the wiring loom to see if I can find a break somewhere.

Thoughts ?
