2. Inspect and clean the left rear wheel speed sensor
3. Check the gap between the sensor and the setting ring (the norm is 0.3–1.5 mm depending on the model)
4. Measure the resistance of the sensor and wiring with a multimeter
5. Inspect the drive ring for damage
6. Replace the sensor or fix the wiring problem
