What does a lambda sensor on a car do?
A lambda sensor, or oxygen sensor, is a vital element in your car’s emissions systems, ensuring that your fuel mixture has the right amount of oxygen for efficient and environmentally-friendly combustion. In this blog post, we’re going to briefly look at what a lambda sensor is, how it works, when you should check it and how to replace it.
How often should I Check my lambda sensor?
To check the lambda sensor, check the tension at the signal wire (in general black color). Usually, after the engine is warm and under normal operation the measurement should alternative between 0.1 and 0.9 volts around two times per second at 2000rpms.
Is the Denso Lambda engine management system trusted?
Denso’s lambda sensors, part of its extensive engine management system range, are said to be trusted by European and Asian vehicle manufacturers (VMs), as well as by customers in the aftermarket.
What is the operating range of a lambda regulation engine?
Thereby when the engine is working, the proportion L is constantly varying in the range 0.9 – 1.1 and this is the lambda regulation operating range.
What do you need to know about a damaged lambda sensor?
A damaged lambda sensor or fault in the fuel system can result in a high air to fuel ratio producing black soot which damages the lambda sensor. Measure exhaust gases to ensure the fuel system is functioning correctly. Check the lambda sensor heater control and sensor heater, rectify any faults before replacing the sensor.
Can a check engine light code be troublesome?
Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes.
Can a fuel additive block a lambda sensor?
Excessive use of any engine or fuel additive can contaminate or block the lambda sensor. Again, address the root cause of the failure before replacing the Lambda Sensor. In this case cleaning the fuel system prior to replacement is required.
Where is the lambda sensor on a Volvo?
The lambda sensor is a small probe first developed by Volvo in the 1970s. The lambda sensor location is the same on every car and it can be found on the car exhaust, between the exhaust manifold and the catalytic converter. In principle, the lambda sensor is the same as an oxygen sensor.
A Lambda sensor measures the amount of unburned oxygen in a vehicle’s fuel exhaust. If the oxygen level is too high or too low, the Lambda sensor sends a signal back to the vehicle’s computer that tells it to adjust the air/fuel mixture so that the vehicle can perform optimally and within emission control …
Why does the Check Engine light come on on my Lambda?
The “Check Engine” light may come on. A vehicle owner will have to have a reputable technician check the code. A cold engine with a faulty Lambda sensor that has unburned oxygen in the catalytic converter may emit a “rotten egg” smell. A malfunctioning Lambda sensor may send an erroneous signal that the air/fuel mixture is too rich.
How does the lambda sensor work on a Hella?
The lambda sensor determines the remaining oxygen content in the exhaust emission, and provides the engine control with an electric signal to control the air-fuel ratio. Scroll through this page and find out about the variants, how they work, test methods, and important information on the correct replacement of lambda sensors.
Can a faulty lambda sensor cause a rotten egg smell?
A vehicle owner will have to have a reputable technician check the code. A cold engine with a faulty Lambda sensor that has unburned oxygen in the catalytic converter may emit a “rotten egg” smell. A malfunctioning Lambda sensor may send an erroneous signal that the air/fuel mixture is too rich.

Can the O2 sensor cause a car to smoke?
When operating properly, the O2 sensor cannot cause your engine to smoke. If the sensor is defective, however, it can cause your car to run either rich or lean. If your car is running excessively rich, you may notice black smoke coming from your tailpipe.

Can a leak from the exhaust damage the sensor?
However, this could be shorter depending on numerous factors that can damage it, mainly because of anomalies coming from the engine. Leaks from the exhaust can also damage the probe. If you notice one of the signs stated above, we recommend you visit a mechanic who can test if the fault is coming from the lambda sensor.
