摘要：
A method and system for monitoring an exhaust gas adsorber includes a comparison module comparing the first exhaust gas constituent signal corresponding to an amount of exhaust gas constituent in an exhaust conduit and a second exhaust gas constituent signal corresponding to an amount of exhaust gas constituent in the exhaust gas adsorber. The system includes a fault module generating a fault in response to comparing in the comparison module.
