P0420 - P1420 Catalyst Error Warning Problem

If the warning light of your car turns on due to the inefficiency of the exhaust catalyst, this problem could be solved with our mini catalyst.
The issue is certainly related to an inefficiency of the lambda sensor or the catalyst, which after several attempts to verify that the carburation remains within the target values set by the manufacturer, not seeing them respected in the allowed time, turns on the warning light.
To solve the removal of the warning light, the most drastic route is to replace both the catalyst and the lambda sensors with a very substantial cost.
While our suggested solution instead is to install this Minikat, a small catalyst that tries to extinguish and solve this error as it increases the catalysis right near where it is measured, namely the lambda sensor.
It should be added that for gas-powered vehicles this Minikat is really a godsend as in our tests it has allowed 90% of the catalyst efficiency error to be permanently extinguished with gas operation where this error is usually more likely to appear.
