Title Cause of error Check point & Normal condition
Check Point
1. Estimate the resistance of each sensor.(Unplugged)
2. Estimate the voltage of each sensor.(Plugged)
3. If the resistance of the sensor is 0 kΩ or ∞, then sensor is abnormal.
If the voltage of the sensor is 0 V or 5Vdc, then sensor is abnormal.
