Catalyst System Efficiency Below Threshold (Bank 1) (P0420)
MONITOR DESCRIPTION
The ECM uses sensors mounted in front of and behind the Three-Way Catalytic Converter
(TWC) to monitor its efficiency.
The first sensor, the air fuel ratio sensor, sends pre-catalyst information to
the ECM. The second sensor, the heat ...

CAUTION / NOTICE / HINT
HINT:
Use the same procedure for the LH side and RH side.
The following procedure is for the LH side.
If the sensor rotor needs to be replaced, replace it together with the
front drive shaft assembly. ...
