Oxygen Sensor
On the B230F engines, the oxygen sensor (Lambda-sond) is electrically heated. The use of a PTC
(Positive Temperature Coefficient) element to heat the Lambda-sond ensures a shorter warm up time
and continuous operation at its working temperature.
This type of Lambda-sond does not require periodic replacement.
Catalytic Converter
This is a supplementary device in the exhaust system, designed to reduce exhaust emissions.
This device is mainly a container with a ceramic material insert, designed to let the exhaust gases pass
through channels in the insert. The channel walls are covered by a thin layer of platinum and rhodium.
These metals act as catalysts, permitting a chemical action to occur without actually taking part in it.
The carbon monoxide content will increase if the Catalytic Converter is damaged.
CAUTION:
Vehicles with Catalytic Converter must use unleaded fuel only. Otherwise the Catalytic Converter will
become damaged and ineffective.
Torque catalytic converter mounting bolts
The Catalytic Converter mounting bolts should be re-torqued at the 600-1,200 mile (1000-2000) km
inspection.
