O2 Codes

Hey folks,


I've recently started seeing O2 codes appearing out of nowhere. This is accompanied by somewhat rough idle and a few misfires here and there. There have been zero drivetrain changes in the last year as I've been working on suspension and brakes.


Here is what I am getting rather frequently:


2C7E Lambda probe behind catalytic converter, trimming control
Error will cause a warning light
Error is not currently present
Test conditions have been completed
Signal or value below threshold


Freeze Frame Information
Event 1Odometer 66688kms 41438miles
voltage Lambda probe behind catalytic converter bank 1 0.06 V
voltage Lambda probe in front of catalytic converter bank 1 1.80 V
Lambda shifting return valve 1 0.00 -
input signal return valve 1 0.00 V



2C6C Lambda probe behind catalytic converter 2, system check
Error will cause a warning light
Error is not currently present
Test conditions have been completed


Freeze Frame Information
Event 1Odometer 66688kms 41438miles
voltage Lambda probe in front of catalytic converter bank 2 1.58 V
resistor Lambda probe behind catalytic converter bank 2 1,792.00 ohm
Engine speed 3,040.00 rpm
voltage Lambda probe behind catalytic converter bank 2 0.63 V





I recently had to install the DP Fix to pass emissions and I am wondering if I somehow mixed the signals from the O2 sensors.


Any suggestions and ideas?
