am interested to understand the p0420, among the other codes

 

My mech says we should chnge the catalytic converter is this true?

 

Could be but you could try the kinds of things others have posted about (this forum / this site). Search will get you ideas that are much cheaper if they pan out.

 

thanks

 

Does Kenya have a tight emissions inspection?

If not, you can gut the cat, and add "cheaters" to the downstream sensors for much less than that convertor will cost.

 

It shows a code for a faulty o2 sensor on that bank, if it is bad then the bank cannot be read correctly by the computer. It may be a just in case code if it cannot monitor the true data. You can try swapping the B1&B2 downstream sensors and see if the codes swap banks also.

 

we removed the honeycomb from the cat since it had melted. seems okay for now
