How are sensors used in the modern aircraft?
Whether it is civil or military aviation, modern aircraft are equipped with electronics systems. Accurate feedback systems and ease of control of aircraft systems are enabled by electronic sensors. Sensors help in measuring various parameters like monitoring, control and navigation.
Which is the most common sensor to be replaced?
The catalyst monitor needs good inputs from both the upstream and downstream O2 sensors to check the operating efficiency. Oxygen sensors are one of the most often replaced sensors. Inputs from the O2 sensors are used by the engine management system to adjust the fuel mixture. This is critical for maintaining low emissions and good fuel economy.
Why do I need to change my sensor system?
As mentioned, a dead battery is another reason why you should change your sensors. Of course, depending on the type of sensors, you may have to replace the entire system or individual sensors.
How does the onboard diagnostic system work on a car?
The Onboard Diagnostic (OBD II) system is capable of detecting most sensor faults if a sensor is not reading within its normal range or if the signal is lost altogether. If a fault is detected, the OBD II system will set a code and turn on the Check Engine light to alert the driver that something is amiss.

When to replace the air inlet temperature sensor?
It should match the air inlet temperature (IAT) reading when the engine is cold, and gradually increase as the engine warms up. The sensor’s resistance also can be checked with an ohmmeter and compared to specifications for various temperatures. If the sensor is not reading correctly, it needs to be replaced.
When to replace the oxygen sensor in your car?
This, in turn, can cause emissions, performance and drivability problems. Except for some early 1980s vintage oxygen sensors, most sensors have no factory recommended replacement intervals. They work until they don’t. In other words, they are designed to last the life of the vehicle or until they fail.
