mhoughton439@yahoo.com Posted September 3, 2016 Share Posted September 3, 2016 I. Using the Torque Pro app to diagnose my P0420 CEL code on my 03 Outback 2.5. I can't seem to get it to graph bank 1 sensor 1. Bank 1 sensor 2 seems to graph fine (seen below) though. For giggles I tried the same thing on my 02 Legacy L 2.5 and got the same thing (this car is also throwing a P0420 but has a new upstream o2 sensor). What am I missing? Is it possible neither o2 sensor is functioning is functioning at all? Does anyone have any ideas how to make Torque graph properly? Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted September 4, 2016 Share Posted September 4, 2016 If the car has California emissions it may be equipped with a front A/F sensor rather than a plain oxygen sensor. IIRC A/F sensors are listed separately in the torque app. Quote Link to comment Share on other sites More sharing options...
