Prius Catalytic Converter Repair

A catalytic converter reduces toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction).

What Causes The Catalytic Converter To Go Bad? 

When your internal combustion engine starts to misfire or burn excessive amounts of oil, the contaminants will not only foul up your Oxygen sensors, they will also clog or burn up your Catalytic Converter. This is why having a check engine light diagnosed immediately is key. Your $300 repair might turn into a $2500 repair! In some cases, your Prius might need a new engine, but don't wait! Keep burning oil and you will need an engine & catalytic converter!

Why Protect The Prius Catalytic Converter?

Unfortunately...the Toyota Prius Catalytic Converters have precious metals inside that are valuable. This has made them a target for thieves throughout California. Another issue is that these cannot be replaced by an aftermarket catalytic converter because of strict California exhaust laws. If your insurance will not cover this, it is best to install a Cat protection shield. It's not a guarantee that thieves won't steal the Catalytic converter from your vehicle but it is a great theft deterrent.

What are the signs you need a new catalytic converter? 

  • Check engine light with a code of P0420
  • Failing smog check
  • Poor engine performance
  • The vehicle will not start or starts for short periods only
  • Excessive noise coming from the exhaust
