Lambda & Oxygen Sensors – Replacement Engine & Exhaust Sensors
Shop replacement lambda and oxygen sensors at Shop4AllParts. Explore vehicle-specific sensors for compatible cars, SUVs, vans and commercial vehicles.
Lambda sensors, also known as oxygen sensors or O2 sensors, measure oxygen in a vehicle's exhaust gases. Their signals help the engine management system monitor combustion and, depending on the sensor's position and the vehicle's design, adjust the air-fuel mixture or assess catalytic converter operation.
Our collection includes replacement lambda and oxygen sensors for a wide range of vehicle applications.
Depending on the vehicle, oxygen sensors may be installed before or after the catalytic converter. Their construction, electrical connectors, cable lengths and operating characteristics vary between applications.
