Procede Harness causing random 02 Sensor codes

KaiserN54 · 12-19-2013, 06:20 PM

I have replaced all 4 sensors- and am still getting various 02 sensor codes, along with occasional 2DED codes (electric circuit). I cannot figure it out. This happens on any mixture of gas and E85, even 100% gas.

A while ago, I had a lose pin in my Procede patch casue problems with my throttle body acting up. Could this be another harness problem?

Could be your map. I changed to the 9-10 aggressive maps and fiddled with some of the maps and user adjustable settings and threw almost every O2 sensor code. I bought new O2 sensors but ended up plugging in a BT1 OBD thingy that I got and it told me
I was running rich. Installed the maps again without changing any settings and it's running perfectly now.

People have also found recessed pins on the DME side causing O2 (and possibly other) issues. I'd check all connections as well.
