Catalytic converter examination: start out the engine and let it warm up till it reaches its ordinary functioning temperature. Raise and preserve the engine RPM during the 2000-2500 range after which you can utilize a electronic automotive pyrometer to acquire Take note on the inlet temperature and outlet temperature of the catalytic converter.
Your Echo’s exhaust incorporates hydrocarbons, carbon monoxide, as well as other destructive gasses. Catalyst system effectiveness is The proportion of such substances faraway from the exhaust process. Oxygen sensors measure these pollutants.
Analysis: The most typical reason behind Nissan P0420 is a bad catalytic converter, but it could be a result of everything from a defective oxygen sensor into a rich or lean running affliction, or misfires.
Nonetheless, if you don’t, there’s a quite simple Option that could come in useful irrespective of for those who’re a specialist or maybe anyone who would like to really know what is Erroneous with their automobile Every time it starts to exhibit indicators of malfunction.
