Code B1479 Description
The B1479 diagnostic trouble code (DTC) indicates a failure in the wiper washer fluid level sensor circuit. This sensor is responsible for monitoring the level of washer fluid in the reservoir and sending this information to the vehicle's computer system. When the sensor circuit fails, it can lead to inaccurate readings or a complete lack of communication with the system, resulting in issues with the washer fluid level display on the dashboard.
Common Causes of B1479
- Faulty washer fluid level sensor.
- Damaged wiring or connectors in the sensor circuit.
- Corrosion or debris affecting the sensor's functionality.
- Issues with the vehicle's computer system interpreting sensor data.
- Low washer fluid level leading to sensor misreadings.
Symptoms of B1479
- Dashboard warning light indicating low washer fluid level stays on even when the reservoir is full.
- Inaccurate or erratic readings of the washer fluid level on the dashboard display.
- Wipers not operating when washer fluid is low, even if there is fluid in the reservoir.
- Intermittent or complete loss of communication with the washer fluid level sensor.
How to Fix B1479
- Begin by locating the washer fluid level sensor, typically found in or near the washer fluid reservoir.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion.
- Test the sensor's functionality using a multimeter to check for proper resistance readings.
- Replace the sensor if it is found to be faulty, ensuring the new sensor is compatible with the vehicle.
- Clear the DTC from the vehicle's computer system using a diagnostic scanner to reset the warning light and ensure proper operation.
Cost to Fix B1479
The typical repair costs for addressing a wiper washer fluid level sensor circuit failure can range from $100 to $300, including parts and labor. However, it is important to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type.
