Component Inspection: Notes

Steering Angel Sensor Check
1. Ignition "ON" & Engine "ON".
2. Turn the steering wheel to the left or right.
3. Measure waveform between signal terminal of the steering angle sensor harness connector and chassis ground with oscilloscope.
  Specification : Check the voltage range (HIGH: 2.9±0.1V-4.4±0.1V LOW: 1.2±0.1V-2.1±0.1V) of the sensor signal in case of turning left and turning right.
  
  If normal waveforms such as Figure, Figure are detected in each condition, It is normal.
