How the Lambda Sensor Works and How to Clean It

Model: (Various brands) Various
Part: Oxygen sensor

In this video tutorial, see how to clean the lambda sensor. The lambda sensor is responsible for fuel mixture, located above the catalyst. It detects the air components inside and sends a signal to the ECU to adjust the mixture. If the sensor is not functioning, it may send incorrect signals, leading to hesitation during acceleration or jerky starts. At this point, take a 22mm spanner and unscrew the sensor; once the sensor is loosened, disconnect the connector using a flat screwdriver. Once the connector is detached, you can finish unscrewing the sensor by hand. To clean the lambda sensor, you can also use an ultrasonic cleaner. Once cleaned, the sensor can be reinstalled in the vehicle.
