Hi guys, over the past few months I've been trying to find the source of an intermittent P1170 code. Unfortunatly I've been able to find the issue. I've replaced a couple things here and there including the front O2 sensor.
I also bought a ELM 327 bluetooth OBDII connector so I could see some live data from my car to help me locate the problem. Well yesterday I decided to log some data and I've plotted the response from both O2 sensors below:
Sorry about the size of the image!
I was hoping some of you around here would be able to tell me if these sensors look like they're functioning normally or if one of them is bad.
And the O2 sensor that was replaced about 4 or so months ago should be the first one (blue line) I believe.
