What is an NO sensor?
A nitrogen oxide sensor or NO. x sensor is typically a high-temperature device built to detect nitrogen oxides in combustion environments such as an automobile, truck tailpipe or smokestack.
What does a NOx sensor do on a diesel engine?
NOx sensors monitor the level of nitrogen oxide being emitted by a diesel vehicle to ensure compliance with emissions regulations. Most engines feature two NOx sensors: an upstream and downstream sensor.
What does sensor mean on a car?
By The Advance Team. Gone are the days when you could turn a screw on a carburetor to tune up an engine. Today’s engines contain sensors to tell the vehicle’s computer what’s going on. Car sensors check for fuel-air mixture, incoming air temperature, wheel speed, and manifold pressure.
Where are the sensors on a new car?
Newer vehicles will have more than one sensor—one “upstream” and one “downstream.” The upstream sensor will be on the exhaust pipe, closer to the engine, while the downstream sensor is situated closer to the muffler and catalytic converter; the idea is to fine-tune the input the engine computer receives by getting two readings.
What is the oxygen sensor in a car?
The oxygen sensor (or O2 sensor) is a key component of your vehicle’s emissions system and dates back to the earliest days of electronic engine controls. Still, many people are unsure about what the oxygen sensor actually does.
Which is an example of a car sensor?
A good example is the car’s pressure sensor. The pressure sensor will relay some voltage depending on the pressure it registers. If the pressure levels go past a certain limit, it sends the info to the central processor in the engine through a wire connection or new age wireless means.
Where is the air temperature sensor on a car?
The intake air temperature sensor measures the air temperature flowing into your car’s cylinders through the intake pipes. It is often integrated with your MAF sensor, but it can also be externally fitted on your intake pipes, at the manifold or close to the air filter box.
