Fault text
Oxygen sensor behind catalytic converter, bank 2, signal

Fault description
O2 Sensor Slow Response - Rich to Lean (Bank 2 Sensor 2)

Condition for fault identification
Test condition:
* Determination of dropout time between 67%
(K_LANK_OBD_SLOPE_F_MAX) and 35%
(K_LANK_OBD_SLOPE_F_MIN) of initial sensor status
* Attempt averaging dropout times using 3
K_LANK_OBD_SLOPE_CNT
* Check whether dropout time >
KF_LANK_OBD_SLOPE_ML_T, then diagnostic fault
code log
Terminal condition: Engine running
Voltage condition:
none

Condition for fault memory entry
The oxygen sensor's drop-out time is monitored and
averaged during K_LANK_OBD_SLOPE_CNT_IO SA
phases

Action in service
1. Check exhaust system for leaks
2. If OK, replace post-cat oxygen sensor LSNK B2

Fault effect and breakdown warning
MIL on after engine runs 2x / no effects on drivability

Driver information
Warning light:
