6. EPA Not all monitors are supported by all vehicles and the exact number of monitors in any vehicle depends on the motor vehicle manufacturer s emissions control strategy Continuous Monitors Some of the vehicle components or systems are continuously tested by the vehicle s OBDII system while others are tested only under specific vehicle operating conditions The continuously monitored components listed below are always ready 1 Misfire 2 Fuel System 3 Comprehensive Components CCM Once the vehicle is running the OBDII system is continuously checking the above components monitoring key engine sensors watching for engine misfire and monitoring fuel demands Non Continuous Monitors Unlike the continuous monitors many emissions and engine system components require the vehicle to be operated under specific conditions before the monitor is ready These monitors are termed non continuous monitors and are listed below 1 EGR System 5 O2 Sensor Heater 2 O2 Sensors 6 Secondary air 3 Catalyst 7 Heated Catalyst 4 Evaporative System 8 A C system OBD II Monitor Readiness Status OBDII systems must indicate whether or not the vehicle s PCM s monitor system has completed testing on each component Components that have been tested will be reported as Ready or Complete meaning they have been tested by the OBDII system The purpose of recording readiness status is to allow inspectors to determine if the vehicle s OBDII system
