U89WBD1A
The crankshaft wheel sensor is a magnetic pick-up type and it is supplied with 5 V power. It outputs sine waveform according to the change in magnetic field occurred by rotation of the crankshaft. Then, the position/ speed of the crankshaft can be determined by the current value through the changed resistance value. The crankshaft wheel sensor detects the position of each piston and sends this information to the ECU which then uses this information to set the injection timing and amount.
The water-in-fuel sensor is installed under the fuel-filter. When water enters the engine fuel system, it can damage the high-pressure fuel pump, filter and injector and cause poor engine starting performance and malfunction. Therefore, when water is collected (45cc or more) on the bottom of the fuel-filter, this water-in-fuel sensor sends a signal to the instrument cluster which then turns on the water-in-fuel warning lamp. Make sure to drain water from the fuel-filter in this case.

The crankshaft wheel sensor is a magnetic pick-up type and it is supplied with 5 V power. It outputs sine waveform according to the change in magnetic field occurred by rotation of the crankshaft. Then, the position/ speed of the crankshaft can be determined by the current value through the changed resistance value. The crankshaft wheel sensor detects the position of each piston to determine the injection timing and amount. This sensor is a magnetic pickup type so its N polar and S polar intersect during rotation of the crankshaft to send 60 signals in total. It detects the position of each cylinder by detecting the position without a tooth on the gear.
