Peace, mercy, and blessings of God be upon you. May God bless you. A link that simulates a catalytic converter to solve the P0420 and P0430 code problem after emptying the converters. It is necessary for the sensor to be sound to give the sensor a correct reading, reduce the carbon smell and fuel consumption, and turn off the check engine light. If it is malfunctioning and you wish, we can provide it within a month from China at a competitive price. Contact me. The part is installed on the rear sensors only after the catalytic converter. When the codes turn off, the following problems often improve: 1- Carbon smell 2- Fuel consumption 3- Starting problem afterwards. The product was recently imported. I noticed that 8-cylinder car owners did not benefit in terms of carbon and consumption, only the light turned off, and a Lexus owner claims he benefited. However, for 6-cylinder cars, some improved fuel consumption and carbon smell, and some did not benefit. The number of customers is very small and not enough to judge the product, and there are many videos praising it. I am only talking about my customers' experience. This product is non-refundable, you might benefit or you might not, and your purchase of it is a risk you bear the consequences of or benefit from its gains. Therefore, do not buy unless you know someone who has installed it on your car and benefited, and ask other sellers, perhaps they can help you.
