An oxygen sensor, also known as a lambda sensor, measures the oxygen concentration in exhaust gas. In compatible vehicles, this information helps the engine management system understand the combustion mixture.
Depending on the sensor type and vehicle configuration, its signal can support air-fuel mixture control and emissions management. The required sensor design depends on the specific engine and exhaust system.
Monitors oxygen concentration in the exhaust gas.
Provides sensor information to compatible engine control systems.
Sensor type and specifications must match the intended application.
Oxygen sensors provide important exhaust gas information for compatible automotive engine management systems.
Measures the oxygen present in exhaust gas to help determine combustion mixture conditions in the engine.
In compatible closed-loop systems, the sensor signal helps the engine control unit adjust the air-fuel mixture.
Oxygen sensor information can support the operation and monitoring of compatible exhaust emissions control systems.
An oxygen sensor responds to the oxygen conditions in the exhaust stream and produces an electrical signal according to its design. A compatible engine control system can use this information to monitor the combustion mixture.
The sensing element is exposed to exhaust gas at its specified installation location.
The sensing element responds to the oxygen concentration or oxygen-related conditions according to its sensor type.
A compatible control system interprets the signal to help manage the air-fuel mixture and related functions.
Oxygen sensors are used in compatible automotive exhaust and engine management systems. Correct selection depends on the engine, exhaust configuration, sensor technology and vehicle manufacturer's requirements.
