So my questions are how to know that the problem in catalytic system by reading O sensors

- Park the car with hand brake pulled and the gear shift in P or N position.
- Warm up the engine.
- Rev up the engine till the fuel cut system is activated.
- If it rev up quickly and starts taking jerks at around 4000 rpm- 5000 rpm the catalytic converter is at its best.
- If the engine does not rev up quickly and abnormal sound is heard near the air filter box, the catalytic converter is clogged and it will trigger the DTC P0420.
