VIDEO: Slow Or Lazy Oxygen Sensor Maintenance
Andrew Markel explains how coolant leaks and oil consumption can lead to a slow, lazy or dead oxygen sensor. Sponsored by Robert Bosch.
Finding Failing O2 Sensors
Oxygen sensors are some of the most often replaced sensors. Inputs from the O2 sensors are used by the engine management system to adjust the fuel mixture. This is critical for maintaining low emissions and good fuel economy. If an O2 sensor gets “lazy” because of old age or contamination, the computer may not be able to adjust the fuel mixture quickly enough as the engine’s operating conditions change. O2 sensors that are failing tend to read lean, which causes the fuel system to run overly rich to compensate. The result is increased emissions and fuel consumption.
Catalytic Converter Replacement Commandments
Catalytic converter replacement can be one of the most arduous repairs a shop takes on. It is not that the repair itself is overly complicated; it is the paperwork, laws and warranty issues that can be the real headache.
Getting the Complete Picture on Converter Efficiency
Engine management systems compensate for changes in engine speed, loads and temperatures by adjusting the amount of fuel injected, spark advance/retard and even when the intake and exhaust valves open. These adjustments can only do so much. Tailpipe emissions are cut further by exhaust gas recirculation (EGR) and secondary air injection systems. The last line
Diagnosing Catalytic Converter Failure Symptoms
Although construction can vary according to engine application, the common three-way catalytic converter contains a reduction and oxidation stage. To create maximum surface area, each stage is generally a ceramic or stainless steel honeycomb substrate covered with a rough silica and alumina wash coat. Both stages of the converter are coated with precious metal catalysts

Using oxygen sensors to identify emissions efficiency
The ASE X1 Certification Test has a section (8 questions) focused on emissions system diagnosis. For that section, among other things, you will need to: • Identify failed catalytic converter(s); determine cause of failure; determine needed repair. • Identify failed oxygen sensor(s) (O2S/HO2S) component(s) and circuitry; determine cause of failure; determine needed repair. • Inspect
