A car's oxygen sensor (or lambda sensor) measures the ratio of oxygen (O2) to fuel, ensuring the efficient performance of the engine. Over time, carbon and other residue can build up on the sensor, leading to inaccurate readings. This can have a knock-on effect on other components of the car.

What is the lambda sensor?

A car's oxygen sensor (or lambda sensor) measures the ratio of oxygen (O2) to fuel, ensuring the efficient performance of the engine.

Where is the lambda sensor located?

The o2 sensor is always located in the engine system, often between the catalytic converter and the exhaust manifold.

Faulty Lambda Sensor Signs

Over time, carbon and other residue can build up on the sensor, leading to inaccurate readings. This can have a knock-on effect on other components of the car, such as:

  • The engine warning light will illuminate on your dashboard.
  • Your vehicle may jerk when starting.
  • Poor engine performance.
  • Higher fuel consumption and exhaust emissions.

Before you get a lambda sensor replacement, your vehicle may need a lambda sensor cleaner.
