- Damaged wiring or connectors in the right front side sensor circuit
- Corrosion or moisture infiltration in the sensor connections
- Faulty sensor component
- Previous improper repairs or installations
- Vibration or physical damage to the sensor or wiring harness
Symptoms of B129D Lincoln
- ABS or traction control warning lights illuminated on the dashboard
- Erratic behavior of the stability control system, such as unexpected activation of ABS or traction control
- Loss of stability or control during driving maneuvers
- Inaccurate speedometer readings
- Vehicle pulling to one side during braking or acceleration
