WebSep 23, 2024 · The first step in troubleshooting a crank sensor is physical inspection. The sensor is at either the front or the back of the crankshaft, so it’s usually located either on the transmission bellhousing or behind the crankshaft pulley. There should be a small air gap, usually about a millimeter or two, between the sensor and the reluctor. WebMar 7, 2024 · Chipped radio-frequency identification (RFID) sensor systems have been studied for structural health monitoring (SHM) applications. However, the use of chip in sensor tags and its standardized narrowband operation contribute shortcomings in cost, durability, and detection capability. This paper presents a novel use of the frequency …
