DTC Description
DTC DETECTION LOGIC
The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the air fuel ratio (A/F) sensor 1. The oxygen
storage capacity of the three way catalyst 1 causes the longer
switching time. To judge the malfunctions of heated oxygen sens ...
