The ECU uses this data to assist in various systems such as stability control, traction control, and power steering.
Common Causes of B3104 Mercury
- Faulty steering shaft position sensor.
- Damaged wiring or poor electrical connections.
- ECU malfunction or communication issues.
- Physical damage to the steering shaft affecting sensor readings.
Symptoms of B3104 Mercury
- Erratic steering behavior or difficulty in steering.
- Stability control system engaging unexpectedly.
- Power steering assistance feeling inconsistent or lacking.
- Illumination of the traction control or stability control warning lights on the dashboard.
How to Fix B3104 Mercury
- Begin by diagnosing the specific cause of the steering shaft position sensor malfunction using a diagnostic scan tool.
- Inspect the sensor, wiring, and connections for any visible damage or issues.
- Replace the faulty steering shaft position sensor if necessary.
- Clear the DTC from the ECU memory and perform a reset to ensure the system recognizes the new sensor.
- Test drive the vehicle to confirm that the issue has been resolved and that the sensor is providing accurate data to the ECU.
Cost to Fix B3104 Mercury
