- Variations in oxygen levels help the engine control module (ECM) adjust fuel mixture for optimal efficiency.
- Different sensor types (heated/non-heated) are used for different locations in the exhaust system.
- Location variations may exist based on engine variants.
Catalytic Converter Sensors
- Sensors monitor the efficiency of the catalytic converter in reducing emissions.
- Catalytic converter sensors measure the effectiveness of the catalytic converter in converting harmful gases.
- These sensors often work in conjunction with O2 sensors.
- Data from these sensors helps the ECM adjust parameters for emissions control.
- Failure of these sensors could indicate issues with the catalytic converter.
