Learn more about Lambda sensor - operation method, diagnosis, causes of faults and replacement intervals.

A lambda sensor is a sensor which measures the residual amount of oxygen in the exhaust gases. It allows determining the air-fuel ratio of the mixture. The engine control unit uses data from this sensor to adjust the process of mixture formation in real-time.

Types

By design, these parts are divided into:

  1. Binary. These sensors can be made of zirconium or titanium. The former type is the most common. Their working temperature is 300°С. Therefore, such devices need some time to heat up and don’t begin working immediately after the engine start. The latter type is durable longevity and requires no atmospheric air for operation. That is why they are often installed on off-roaders, as they can operate even underwater, for instance, when crossing bodies of water.
  2. Wideband. Their design features two sensitive elements. Such sensors ensure more accurate readings. However, temperature variations and condensed water are detrimental to them. The vehicle OBD system monitors this type of sensors; you can read the fault codes with a special scanner.

By the presence of a heating element, there are the following types of lambda sensors:

  1. With a heating element. They last for about 100.000 kilometres. They feature a built-in heater, that’s why they are more efficient and start operating faster.
  2. Without a heating element. Such sensors are designed for 50.000–80.000 kilometres of mileage. They reach the working temperature due to contact with hot exhaust gases. Nowadays, they are used less often, as they take quite a lot of time to heat up.

Depending on the type of housing, these components can be threaded or flanged. Moreover, some of them are sold with the connector, while others use the connector of the old part.

Operating tips

To avoid engine malfunctions, it is recommended to check the lambda sensor every 30.000 kilometres of mileage or every time you have your car serviced and emissions tested. Fill up at proven petrol stations only: vapours of leaded petrol damage the sensitive element of the device. For the same reason, it is not recommended to use silicone-based sealants for mounting exhaust system elements.

Also, try to avoid exhaust system overheating. Properly adjusted and correctly working ignition system is essential for this.

When installing a new oxygen sensor, carefully follow the instructions of its manufacturer and recommendations of the carmaker. Always clean the mounting location. Tighten the threaded joint with a torque wrench and observe the required tightening torque. Some manufacturers recommend greasing the thread. Just don’t let the lubricant get onto the sensitive element of the part.

Symptoms of malfunctions

Usually, all defects of oxygen sensors have the same symptoms. They are reduced engine power and performance, poor acceleration, increased fuel consumption, unstable idling. Sometimes, you might even hear a specific cracking sound near the part location after you stop the car.

Causes of malfunctions

Malfunction of the sensitive element is mostly caused by the formation of carbon deposits on its surface. This occurs when you use additives not allowed by the vehicle manufacturer, or if the engine rotating assembly is worn out, the piston rings and valve oil seals are damaged or the crankcase ventilation system is clogged. Moreover, the sensitive element of the lambda sensor may burn out if the fuel keeps burning in the exhaust system. Wiring malfunctions are often caused by voltage variations in the vehicle mains. Also, wires abrade over time.

How to find out that a lambda sensor is malfunctioning

The signs that help to detect a defective lambda sensor:

  • the vehicle consumes more fuel;
  • the “Check Engine” indicator on the dashboard often lits on;
  • power unit idling is unstable;
  • the power unit loses power and often overheats;
  • slower reaction of the car to the accelerator pedal;
  • the vehicle moves jerkily;
  • pops are heard when the engine is running;
  • exhaust gases have a more distinctive unpleasant smell.
Where are lambda sensors installed?

Depending on a vehicle’s make and model, production year and engine capacity, its manufacturer installs from 1 to 4 devices. They are placed before and after the catalytic converter. Usually, their exact location is specified in the vehicle service and repair manual.

How to test a lambda sensor yourself?

You can make DIY diagnostics of the upstream lambda sensor. We recommend you to visit a garage for testing other sensors.

First, find the sensor using the vehicle’s service and repair manual. Inspect the part. For this, unscrew its fasteners and disconnect contacts and remove the sensor. A part in good condition should not have any mechanical defects and deposits, and its wiring should not have tears, traces of melting and corrosion.

If you have a VOM (volt-ohm-milliammeter), check the part measuring its main operating values. We recommend watching tutorial videos and studying the sensor connection diagram. You will need to:

  1. Start the engine and let it run for a few minutes.
  2. Shut it down and open the bonnet.
  3. Turn on the ignition.
  4. Connect the VOM probes to the heating circuit wires of the lambda sensor and measure input voltage. It should be 12 V.
  5. Check reference voltage by connecting the probe to the signal wires of the sensor. Connect the negative probe to the car bodywork. The received value should be less than 0,45 V.
  6. Check resistance of the sensor heater on an unplugged socket. Its working value varies within 2-10 Ohm. Precise values for your car are specified in the vehicle’s service and repair manual.
  7. Start the engine and connect the VOM probes to the sensor socket. Increase the engine rotation speed to approximately 3,000 rpm. Measure voltage. It should increase by 0,1–0,9 V.
