It converts around 98% of the harmful fumes produced by a car engine into less harmful gases. It is composed of a metal housing with a ceramic honeycomb-like interior with insulating layers.
Here are five signs that something may be wrong with your catalytic converter: 1  Your vehicleâs fuel efficiency suddenly drops. 2  Your vehicle doesnât accelerate when you step on the gas pedal. 3  Your vehicle may refuse to start.  Your vehicle fails an emissions 1  test. The MIL or Check Engine light comes  on.
