Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Catalytic Converter Operation
All models use a dual bed monolithic-type converter with "downstream" air injection. The injection of air between the 2 beds allows more complete oxidation of HC and CO in the closed loop mode. In order for this converter to be effective, precise control of the oxygen content of exhaust gases entering the converter is necessary; thus, the need for the oxygen sensor, MCU and feedback carburetor.
