Comprehensive Components Monitoring
WARNING: This page is about a different car, the 2004 Kia Rio. However, it is still accessible from the selected car via links, so may be relevant.
Any input or output components that can affect emissions or any input or output component used to monitor any other monitored component/system is monitored.
The lack of circuit continuity and rationality, and out-of-range values to ensure proper operation of the input devices, are monitored for proper response to ECM commands.
