Code B1255 Mercury Description
The B1255 diagnostic trouble code (DTC) for Mercury vehicles indicates that the left rear tire pressure sensor and transmitter assembly is not programmed. This means that the tire pressure monitoring system (TPMS) in the vehicle is unable to communicate with the sensor in the left rear tire. The TPMS is a crucial safety feature that monitors the air pressure in each tire and alerts the driver if there is a significant drop in pressure. When a sensor is not programmed, the system cannot accurately monitor the tire pressure, potentially leading to unsafe driving conditions.
Common Causes of B1255 Mercury
- Improper installation of the left rear tire pressure sensor and transmitter assembly.
- Faulty sensor or transmitter in the left rear tire.
- Communication error between the sensor and the TPMS module.
- Electrical issues within the TPMS system.
- Corrosion or damage to the sensor or transmitter assembly.
Symptoms of B1255 Mercury
- TPMS warning light illuminated on the dashboard.
- Inaccurate tire pressure readings displayed on the instrument cluster.
- Loss of communication with the left rear tire pressure sensor.
- Increased risk of driving with underinflated tires.
How to Fix B1255 Mercury
- Begin by checking the tire pressure in all tires, including the left rear tire.
- Inspect the left rear tire pressure sensor and transmitter assembly for any visible damage or corrosion.
- Attempt to reprogram the sensor using a TPMS programming tool.
- If reprogramming is unsuccessful, replace the left rear tire pressure sensor and transmitter assembly with a new unit.
- After replacement, reprogram the new sensor to sync with the vehicle's TPMS module.
Cost to Fix B1255 Mercury
The cost of repairing a left rear tire pressure sensor and transmitter assembly not programmed can vary depending on the make and model of the vehicle, as well as the labor rates in your area. Typically, the cost of a new sensor and transmitter assembly ranges from $50 to $200, with additional labor costs of $50 to $150. Therefore, the total repair cost could range from $100 to $350. It's recommended to contact local auto repair shops for accurate pricing based on your specific vehicle. Labor rates typically range from $80 to $150 per hour, but can vary based on location and shop.
