    Hi All, my Prius has the P0420 code. The CAT was replaced with the React brand but the light has come back on after only 2 months.

    Anyone who has Klarius fitted, has the engine management light stayed off?

    Also is there any other brand people have had successes with?

    Any help will be really appreciated

    Was their additional service when this work was done, like cleaning and inspecting the 02 sensor?

    The O2 sensors were not touched.

    I spoke with Toyota and they mentioned that the sensors have their own fault code, so as it is only P0420 they believe it's the CAT, but obviously don't want to spend £2k
