Repair Verification
Important: An IC circuit fault condition will result in an engine misfire, and under certain driving conditions could possibly overheat the
3-way catalytic converter.
1. Install any components or connectors that have been removed or replaced during diagnosis.
2. Perform any adjustment, programming, or setup procedures that are required when a component or module is removed or replaced.
3. Start and run the engine. With a scan tool, monitor the IC circuit status parameters. All IC circuit status parameters should display OK.
锟斤拷If another DTC is present, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code
Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle) and perform the appropriate diagnostic.
4. To verify that the performance of the catalytic converter has not been affected by the condition that set this DTC, perform the Repair
Verification for DTC P0420 or P0430. Refer to DTC P0420 or P0430 (See: P Code Charts/P0420).
