ignition type engines, the available monitors are different too.
The following monitors are to be used for spark ignition engines only
1. EGR System
2. O2 Sensors
3. Catalyst
4. Evaporative System
5. O2 Sensor Heater
6. Secondary air
7. Heated Catalyst
The following monitors are to be used for compression ignition
engines only:
