go to this link for fault code P0420
all this read the catalytic converter is most likely worn out.
This Definition of P0411 is : Secondary Air Injection System Incorrect Flow Detected
What does this mean? u have a electric air pump that pumps fresh air into the exhaust system during cold start, this reduces exhaust emissions, that pump is defective, replace it.

Check this possible causes:
- Air leaks present in the exhaust manifold or the exhaust pipes
- Fuel pressure is too high (i.e., causing a rich air fuel mixture)
- HO2S may be contaminated (due to improper fuel or silicone)
- HO2S signal high or low reference circuit has high resistance
- HO2S heater element has failed, or the heater circuit is open
- PCM has failed
Test wires and harnesses. Hope helps.
