To replace the sensor, you do not need to remove the mirror; you only need to remove the housing.
Release the sensor from the clip and cut the wire (several centimeters long).
When installing a new sensor, solder the wires.

| 0-5 | 5400 - 6200 |
| 6-10 | 4400 - 5400 |
| 11 -15 | 3700 - 4400 |
| 16-20 | 3000 - 3700 |
| 21-25 | 2500 - 3000 |
| 26-30 | 2100 - 2500 |
| 31-35 | 1700 - 2100 |
| 36-40 | 1450 - 1700 |
