The catalytic converter in these vehicles is of a three way type that oxidizes as well as reduces the emissions of hydrocarbons, carbons mono oxide and oxides of nitrogen into nitrogen, carbon di oxide and water thereby eliminating the dangerous exhaust constituents. Although the system is self-monitoring and draws minimal current there would be occasions that will necessitate the inspection of the system, such as when the vehicle is being lifted, or the exhaust system is being serviced. All connections in the exhaust pipe assembly must be examined for looseness as well as the clamps or fasteners of any harmed or cracked part. Also, the plastic converter housing should be inspected for dents or any other signs of damage that may affect the function of the device and the metal protector plate beneath it and the heat insulator on top in terms of damage and loose screws.
