P0453 Toyota - 2006 4Runner

Question

My car, a fairly used was purchased in April and is being used in Nigeria. It showed this fault code through OBDII Scanner. The EVAP Control Emission Control was replaced with a 2005's but it now shows fault code P0430 which is Catalyst System Efficiency Below Threshold Bank 2. What should I do?

Answer 1

HI there,

These codes are completely unrelated. P0430 is for the bank 2 catalytic converter below threshold. This means the converter is not working as it should. This means you either have a problem with the converter or possibly the rear O2 sensor on bank 2.
