The lambda sensor is typically located in the exhaust manifold or downpipe before the catalytic converter.
You may need a wrench or socket set, penetrating oil, and an OBD-II scanner.
It is recommended to replace the lambda sensor every 60,000 to 100,000 miles, but follow the recommendations for your car make and model.
It is not recommended to clean the sensor; replace it if it's faulty.
If the sensor fails, it can lead to poor fuel economy, increased emissions, and reduced engine performance.
The 4-pin connector provides power to the sensor's heater and transmits the oxygen level data to the engine control unit (ECU).
Use an OBD-II scanner to read the error codes. This may indicate a faulty sensor or related issue. Inspect the sensor for damage and check the electrical connections. Replace the sensor if necessary.
