Transmission Speed Sensor: Description and Operation
SPEED SENSOR 2DESCRIPTION
- The speed sensor 2 is a magnetic pick-up type revolution sensor.
- This sensor is installed on the transmission converter case and detects the transmission output gear rotation speed.
- 8 pulses are sent to speedometer per rotation of speed sensor driven shaft.
CONSTRUCTION
The speed sensor 2 consists of a magnetic resistance element, magnet ring, driven shaft, spring, etc.
OPERATION
1. As the driven key rotates, the magnet turns to change the magnetic field of the coil
2. The coil generates power corresponding to a change in the magnetic field.
3. One turn of the driven key in the speed sensor sends 8 pulses of AC signal to the combination meter.
