P0420 THREE WAY CATALYST FUNCTION
DTC LogicINFOID:0000000001670968
DTC DETECTION LOGIC
The ECM monitors the switching frequency ratio of heated oxygen
sensor 1 and heated oxygen sensor 2.
A three way catalyst (manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of heated oxygen sensor 1 and heated
oxygen sensor 2 approaches a specified limit value, the three way
catalyst (manifold) malfunction is diagnosed.
