2000 Honda Odyssey CODE PO420.WHAT NEED TO BE REPLACE? ANSWER XXXXXXXXXXXXXX Code PO420 is catalytic converter efficiency low bank 1, sensor1. You did not state as to the year,make and model of the car as well as the engine size. I am a member of IATN and the majority of there fixes was related to someone installing an AFTER MARKET converter. There is a big difference. I strongly suggest that you go to a repair shop with the proper equipment as well as a very good tech to diagnosis the problem. You could replace parts and never fix the problem.jd1709
Probably the bank 1 catalytic converter needs replacement.
For example the ammonia production; the magnetite catalyst is the most common.
It has to do with your cars exhaust/emissions system, more specifically, your Catalytic Converter (Catalyst). If it is 'below threshold', then it is basically worn out and needs to be replaced. The Catalytic Converter super-heats the exhaust gases to reduce emissions into the atmosphere. Take it to your local auto repair shop to have it inspected to be sure. There is usually no charge to look at it. Be prepared to spend anywhere from $250 to over $1000 to replace it, depending on what type of Converter your car has. Hope this helped
The work done by the catalyst is to change the mechanism of a reaction, actually the alternate way using the catalyst needs lesser energy to the same reaction without the catalyst.
Needs to be serviced/repaired
The minimum amount of stimulation a person needs to detect a stimulus 50 percent of the time is called the absolute threshold. This threshold differs for each individual based on their sensory abilities and can vary depending on factors such as noise levels and attention.
Neither Marques nor Leland needs his bike repaired.
Perhaps it is broken and needs to be repaired.
your transmission needs repaired
Ozone needs to be repaired. For this we need to stop using CFC's.
Depends on what needs to be repaired, how much of the fence needs repairment, and who is doing the repairs.
For it to solidify it needs a catalyst of some sort, and the relatively rough (compared to the rest of the liquid) edge of the bowl serves as that catalyst.
