With a relatively large number of oxygen-sensor suppliers, it can be difficult to get past the sales pitch and find out exactly what sensor technology (not brand) will best match your process, procedures and budget. What's best for neutral hardening is often poorly suited to high %C ...
Resistance measurements send voltage into a circuit and check the amount returning. How does an O2 sensor work? An Oxygen sensor is a chemical generator. It is constantly making a comparison between the Oxygen inside the exhaust manifold and air outside the engine. If this comparison shows littl...
The first ZrO2 square works as an electrochemical oxygen pump, evacuating or re-pressurising the hermetically sealed chamber. Depending on the direction of the DC constant current source, the oxygen ions move through the plate from one electrode to the other, this in turn changes the oxygen con...
There are many solvents available in the market used specifically for dissolving grime and buildup accumulated on various parts of automobiles. These solvents do not damage other parts of the vehicle. So when it comes to how to clean an oxygen sensor, you can use a solvent. The solvents may...
The oxygen sensor in your Chevy Aveo is an important component of your vehicle. It is responsible for regulating oxygen levels in your fuel. This controls your gas mileage as well. If the oxygen sensor fails, your Aveo could run poorly and your gas mileage would go down drastically. You ca...
Leasson learned: probe the oxygen sensor pins if you experience problems: Pin 1-2 is the pre-heating element, and should show around 5-6 Ohm (meaning that the pre-heating must be using around 60W) All other combinations of pins should show a capacitance around 50 pF There is a clear ...
The wide band oxygen sensor responds to changes in the air/fuel mixture in less than 100 milliseconds. The Precision Wideband Controller circuit is intended to be used to directly control the fuel mixture, so it needs to be accurate and repeatable. When tuning an engine on the road or on...
You can also use a voltmeter or digital storage oscilloscope (DSO) to check the sensor's output. Specs vary, but generally a cold coolant sensor will read somewhere around 3 volts. As the engine warms up and reaches operating temperature, the voltage drop should gradually decrease down to ab...
2. Oxygen Sensor A catalytic converter is an important component of a vehicle’s emissions system, which converts harmful pollutants into less harmful substances, such as turning carbon monoxide into carbon dioxide. A problem with the catalytic converter will set off a vehicle’s check engine ligh...
Poor air quality and hazards posed by asphyxiates and toxic gases are some of the most common hazards faced in a confined space. Learn how to identify them in time.
