A flame sensor is a safety device used in gas appliances, such as furnaces and water heaters, to detect the presence of a flame. When the flame is lit, the sensor generates a signal that tells the appliance to continue supplying gas. If the flame goes out, the sensor will stop the gas supply, preventing…
A throttle position sensor (TPS) is a sensor used to monitor the position of the throttle valve in an internal combustion engine. It is typically mounted on the throttle body and measures the angle of the throttle valve as it is opened and closed. The TPS is used by the engine control unit (ECU) to…
A knock sensor is a device used in internal combustion engines to detect the presence of knocking, a condition that can occur when the fuel in the engine ignites too early, resulting in a loss of power and potentially damaging the engine. Checking a knock sensor is an important part of maintaining an engine, as…
A crankshaft sensor is a device that monitors the position and speed of the crankshaft in an internal combustion engine. This information is used by the engine’s electronic control unit (ECU) to control the timing of the ignition and fuel injection systems. A faulty crankshaft sensor can cause a variety of problems, including engine misfires,…
A mass airflow (MAF) sensor is a device used to measure the amount of air flowing into an internal combustion engine. It is typically located in the intake manifold, and its readings are used by the engine’s computer to calculate the amount of fuel to inject. A faulty MAF sensor can cause a variety of…
A knock sensor is a device used in internal combustion engines to detect the presence of knocking, which is an abnormal combustion event that can damage the engine. The sensor is typically mounted on the engine block and uses a piezoelectric element to convert the mechanical vibrations of the engine into an electrical signal. The…
Maintaining the cleanliness of your camera’s sensor is essential for achieving high-quality images. Dust particles can accumulate on the sensor over time, causing spots or blurs to appear in your photos. Regularly checking for and removing dust from your sensor is therefore crucial for ensuring optimal camera performance. There are several methods you can use…
An iPhone water sensor is a small indicator that changes color if the device has been exposed to liquid. This can be helpful in determining if your phone has been damaged by water, even if it is not immediately apparent. To check the water sensor, look for a small white or red dot next to…
A manifold absolute pressure (MAP) sensor is a device used to measure the pressure of the air entering an engine. This information is used by the engine’s computer to calculate the amount of fuel to inject and the timing of the spark plugs. A faulty MAP sensor can cause a variety of problems, including: Poor…
