Hey guys - Trying to chase down a o2 code gremlin.
Getting the code 2C3D "Lambda probe in front of catalytic converter, control failure".
The O2 sensors and my Single Turbo setup are both 4k miles old and have not presented any issues until now.
Symptoms:
- When I clear the code, AFR1 and AFR2 are live and both reading as expected. Eventually the code comes back up and AFR in Bank 1 goes to 20. My thought is that the O2 sensor in Bank 1 is working as expected as the same issue persists when I changed the O2 sensor to a spare one I had.
-The code specifies "Line Fault" or "Control Failure"
-SES Light is on
Attempted Fixes:
-Swapped O2 sensor in Bank 1 with another working O2 sensor, code persists
-Checked JB4 Harness and wiring, looks OK
-Reset Adaptations multiple times via JB4/MHD
Setup:
-JB4 with custom MHD Backend Flash
-DocRace 6266
-Eldor Coils/ NGK 95706 @ .20
Any help would be appreciated, working on getting logs when it's not wet outside.
