Method for Troubleshooting the P0420 Indicator Light Fault
Oxygen Sensor
Check the voltage of sensors and whether the oxygen sensor is damaged, and inspect for any faults in the wiring.
Appearance and Sound
When abnormal noise is heard, please check whether the appearance and carrier of the catalytic converter are damaged, blocked, burned, etc.
Exhaust System
Check if there are any faults in the exhaust system, such as exhaust leaks or blockages in the exhaust pipe.
Fault Code
You can use a diagnostic tool to clear the fault codes. After clearing them, restart the vehicle and check the malfunction indicator light.
The Reasons for Initial Failure
Excessive Temperature
If excessive exhaust emissions occur, the HC and CO entering the catalytic converter will undergo transitional oxidation reactions, leading to an excessively high temperature within the catalyst；When a gasoline engine is operating normally, the temperature at the exhaust outlet can reach 1292°F, which may exceed the optimal operating temperature and reduce its lifespan.
Chronic Poisoning
Sulfur(S) and Plumbum (Pb) in gasoline, as well as Phosphorus(P) and Zinc(Zn) in lubricating oil, form oxide particles after combustion in the engine, which adsorb onto the surface of the catalyst. This prevents the catalyst from contacting the exhaust gas, thus losing its catalytic activity.
Surface Carbon
When a car operates at low temperatures for an extended period, the catalytic converter fails to activate. Smoke emitted from the engine will adhere to the surface of the catalyst, preventing it from coming into contact with CO and HC. Over time, this causes the pores of the substrate to become clogged, affecting its conversion efficiency.
Oxygen Sensor Circuit Malfunction
If the fuel contains lead or silicon, it can lead to oxygen sensor poisoning. Additionally, improper usage can cause oxygen sensor carbon buildup, ceramic fracturing, heater resistor wire burnout, internal wiring detachment, and other malfunctions. Oxygen sensor failure can result in improper air-fuel ratio and reduced catalytic converter efficiency.

This catalytic was a great value for the price. It installed perfectly. The only drawback was 2 of the included bolts were the wrong thread pitch so I had to pickup a couple from my local hardware store

Like tittle says. It doesn't fit it. Doesn't even match. Bought another one besides this one and same issue. I don't know why Amazon fit says it fits when it clearly doesn't

La verdad se lo instaló mi mecánico y quedó a la perfección no tengo queja solo que me marca un sensor que ya conseguir pero a funcionado de maravilla.

Ne ressemble pas trop au catalyseur sur la photo et aurait pu mettre au moins les 4 bolts au lieu de juste 2 mais compatible malgré tout
