Oxygen Sensor - Function: Monitors the oxygen level in the exhaust to help the engine management system maintain an optimal air-fuel ratio, improving combustion efficiency and reducing emissions. - Compatibility: Designed for standard automotive exhaust systems with common oxygen sensor connectors and mounting threads. Check your vehicle’s service information to match the correct model and connector type. - Size and material: Compact sensor assembly with a durable housing and protective coating suitable for heat and vibration in engine bays. - Performance: Provides fast response to changing exhaust conditions and reliable readings within typical operating temperatures, contributing to consistent engine performance and catalyst protection. - Benefits: Supports accurate fuel metering, can improve fuel efficiency, and reduces emissions when functioning correctly. - Use scenarios: 1) Replacing a faulty O2 sensor during routine maintenance to restore fuel economy and emissions performance. 2) Installing after exhaust repairs or upgrades to ensure proper sensing and engine calibration. 3) Diagnostic replacement when the check engine light or diagnostic codes indicate an oxygen sensor issue.
