Circuit Operation
- The front propeller shaft speed sensor generates 0 <=> 5 volts pulse signal when the front propeller shaft rotates. The pulse signal frequency increases with a rise in front propeller shaft speed.
- The front propeller shaft speed sensor is connected to the transfer-ECU (terminals 7 and 18) via the front propeller shaft speed sensor connector (terminals 1 and 2).
- The transfer-ECU detects the front propeller shaft speed by the signal input to terminal 7.
- The front propeller shaft speed sensor generates the pulse signal as the hole in the front output shaft pass the magnetic tip of the sensor.
