Circuit Operation
- The rear propeller shaft speed sensor generates 0 <=> 5 volts pulse signal when the rear propeller shaft rotates. The pulse signal frequency increases with a rise in rear propeller shaft speed.
- The ear propeller shaft speed sensor is connected to the transfer-ECU (terminals 9 and 18) via the rear propeller shaft speed sensor connector (terminals 1 and 2).
- The transfer-ECU detects the rear propeller shaft speed by the signal input to terminal 9.
- The rear propeller shaft speed sensor generates the pulse signal as the hole in the rear output shaft pass the magnetic tip of the sensor.
