Signs Of A Bad Catalytic Converter

  • A catalytic converter is the part on a car that
    deals with the emissions and it's main aim is to
    reduce pollution. 
  • The catalytic converter is usually an oval shaped
    metal shell, inside it is an element made of a
    ceramic honeycomb core
  • The job of the catalytic converter is to simply
    control and reduce emissions, it does this by
    catalyzing a redox reaction.
  • A catalytic converter can fail and will then need
    to be replaced.

There are a few tell tale signs when a catalytic
converter is started to fail.
  • 1. A reduction in power, this could be because
    the catalytic converter is blocked.

2. Engine light comes on and when scanned tells
your the catalytic converter is the cause. 3. A
smell of rotten eggs is always a big sign there
is an issue with the catalytic converter, not a
pleasant smell at all! 4. If you can here a
rattle in the exhaust the chance is it is either
the heat shield or the catalytic converter
5
  • 5. Tap test, you can tap the catalytic converter
    and then tap the still exhaust pipe next to it,
    if they sound the same your catalytic converter
    is empty and will need replacing.

  • Whenever we buy a scrap car the first thing we do
    is the tap test, you should here a hollow noise
    if it is empty and a heavy noise if full.
