B106B Mercury Code - Tire Pressure Sensor Low Battery
Quick Answer
If there is a fault in the Tire Pressure Monitoring System (TPMS), such as a damaged or missing sensor(s), damaged module or a communication issue within the vehicle, DTCs are set in the Smart Junction Box (SJB), the TPMS warning indicator will flash for 70 seconds and then remain ON solid when the ignition switch is turned to the ON position and the message center (if equipped) will display TIRE PRESSURE SENSOR FAULT. Common causes include Faulty Tire Pressure Sensor(s), Tire Pressure Sensor Battery. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Frequently Asked Questions about B106B Mercury Code
1. What are the common symptoms of OBDII code B106B in a Mercury related to tire pressure sensor low battery?
- The common symptoms include a tire pressure monitoring system (TPMS) warning light illuminated on the dashboard, inaccurate or missing tire pressure readings, and potential issues with the TPMS functionality.
2. What typically causes the OBDII code B106B in a Mercury for tire pressure sensor low battery?
- The most common cause of this code is a low battery in one or more tire pressure sensors, which can lead to a loss of communication with the TPMS module.
3. How can I diagnose the tire pressure sensor low battery issue in my Mercury triggering the B106B code?
- A diagnostic scan tool capable of reading TPMS sensor data can help identify which specific tire pressure sensor has a low battery. Alternatively, visiting a mechanic with specialized equipment can also pinpoint the problematic sensor.
4. Can I replace the tire pressure sensor battery myself to fix the B106B code in my Mercury?
- Replacing the tire pressure sensor battery can be a delicate process that requires specific tools and expertise. It's recommended to consult a professional technician to ensure proper installation and calibration of the new battery.
5. Are there any temporary solutions to address the OBDII code B106B related to tire pressure sensor low battery in my Mercury?
- In some cases, simply driving the vehicle for an extended period can recharge the tire pressure sensor batteries. However, if the issue persists, a battery replacement may be necessary.
6. Will driving with the B106B code for tire pressure sensor low battery in my Mercury cause any safety concerns?
- While driving with the code may not pose an immediate safety risk, it's important to address the underlying tire pressure sensor issue promptly to ensure accurate monitoring and early detection of potential tire issues.
7. How much does it typically cost to replace a tire pressure sensor battery in a Mercury to resolve the B106B code?
- The cost of replacing a tire pressure sensor battery can vary depending on the model of your Mercury and the labor rates of the repair shop. Generally, it can range from $50 to $200 per sensor.
8. Can a faulty TPMS module trigger the B106B code for tire pressure sensor low battery in my Mercury?
- While it's rare, a malfunctioning TPMS module can sometimes misinterpret low battery signals from the tire pressure sensors, leading to the B106B code. It's advisable to have the entire TPMS system checked for proper functioning.
9. How often should I expect to replace tire pressure sensor batteries in my Mercury to prevent the B106B code from recurring?
- Tire pressure sensor batteries typically last between 5 to 10 years. However, factors like driving habits, temperature fluctuations, and sensor quality can affect battery life. Regular TPMS system checks can help anticipate and address battery issues before triggering the B106B code.
10. Is resetting the TPMS system necessary after replacing a tire pressure sensor battery to clear the B106B code in a Mercury?
- Yes, resetting the TPMS system is crucial after replacing a tire pressure sensor battery to recalibrate the sensors and ensure proper communication with the TPMS module. Consult your vehicle's manual or a technician for specific reset procedures.
