Question 1

Denso Lambda Sensors

Accepted Answer

The Lambda sensor measures the amount of oxygen in the exhaust gas and sends this information to the car’s computer, the computer then works out if the engine is running too rich (too much fuel) or too lean (too much air) and adjusts to compensate. Because the sensors are exposed to very high temperatures when the engine is running, even if the vehicle is parked and idling, they will begin to deteriorate over time. As one of the world's foremost developers and manufacturers of original vehicle parts and systems, DENSO's understanding of lambda sensor technology is unrivalled. Since they were first produced in 1977, DENSO has become one of the leading lambda sensor suppliers in the world, with several hundred million of devices in cars worldwide. As the automotive industry continues to improve its emission standards, DENSO's engineering advances ensure the improvement their Lambda sensors, featuring pioneering sensor technologies that help cars to burn fuel more efficiently and produce fewer emissions.

Question 2

Buying & Fitting Guide

Accepted Answer

To ensure that you get the correct lambda sensor, it is best to check the size and shape of the one currently installed so you can compare with the listed sensors. Some important information for selecting the correct lambda sensor is the type of exhaust system, fitment; sensor may be fitted before or after the catalytic converter (upstream or downstream respectively), whether the sensor is heated or non-heated, sensor type (narrowband or wideband) and date limitation of the unit (The number and location of the lambda sensors are specific to every vehicle's year, make and model).

Question 4

Helpful Tips

Accepted Answer

An oxygen sensor may get damaged due to normal wear and tear. However, over time, carbon deposits may build up over the sensors, preventing them from functioning properly. The sensor can also become contaminated with silicon content from the coolant or anti-freeze. When the oxygen sensor begins to fail, it will exhibit symptoms such as; rough engine idling, poor fuel economy, increased emissions and misfiring of the engine. Having your oxygen sensor regularly cleaned for impurities can ensure their proper function. Some cars have a special O2 sensor light on their dashboard that indicates when to check the oxygen sensor. Unheated sensors usually last 30,000 to 50,000 miles, while newer oxygen sensors need to be replaced at about 100,000 miles however, it should be checked at regular intervals to ensure that it is working properly (approx. every 30,000 km).
