3918025300 SENSOR-CRANKSHAFT POSITION 39180-25300/ Hyundai TG Grandeur
Net weight in plastic bag : 0.061kg
Gross weight in box : 0.083kg
In MOBIS brand, there is Hyundai brand box and Kia brand box.
It’s produced by Continental Automotive Korea. Made in Korea.
I found the manufacturer indication on Kia box. In Hyundai box I couldn’t find it. Some packages have that info and some haven’t. But I guess not only one manufacturer produce it. It’s pretty inconsistent.
More detailed photos of this sensor:
A crank sensor is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on petrol engines.From Wikipedia : https://en.wikipedia.org/wiki/Crankshaft_position_sensor
The functional objective for the crankshaft position sensor is to determine the position and/or rotational speed (RPM) of the crank. Engine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing. In a diesel the sensor will control the fuel injection. The sensor output may also be related to other sensor data including the cam position to derive the current combustion cycle, this is very important for the starting of a four stroke engine.
Those sensor are sold actively in US but not in Middle East and Russia, CIS. I heard that all mechanics in US usually change those sensors when they repair the car. Is it correct? Please comment me if anyone knows about it.
