Abstract:
An oxygen storage capacity (OSC) monitoring system for a vehicle having a catalytic converter includes a control module that determines a measured OSC based on an inlet sensor signal (ISS) that is responsive to an oxygen content of exhaust flowing into the catalytic converter. The control module determines a normalization ratio based the measured OSC and determines a PASS/FAIL status of the catalytic converter based on the normalization ratio.
