Overview of the Ford Taurus Tire Pressure Monitoring System (TPMS)
The Ford Taurus TPMS uses sensors in each wheel to monitor tire pressure. When the system detects a problem, like low tire pressure or a faulty sensor, it shows a “Tire Pressure Sensor Fault” message on the dashboard. Common causes of this issue include:
- Malfunctioning or damaged TPMS sensors
- Sensor battery expiration (usually after 5-10 years)
- Interference or electrical issues within the system
- Calibration issues, especially after tire rotation or replacement
Step 1: Check Tire Pressure
Start by confirming that all tires have the correct pressure to rule out a low-pressure alert. Here’s how:
- Use a Tire Pressure Gauge: Check each tire’s pressure manually with a gauge. Compare the readings to the recommended PSI (found on the driver’s side door sticker or in your Ford Taurus manual).
- Inflate as Needed: If any tires are under-inflated, inflate them to the correct PSI and drive for a few miles. If the “Tire Pressure Sensor Fault” warning persists, it’s likely a sensor issue.
Step 2: Attempt a System Reset
A reset can sometimes clear the fault if there’s no real sensor damage. Ford Taurus owners have several ways to do this:
- Drive at Moderate Speed: A short drive (about 10 minutes) above 20 mph may prompt the TPMS to recalibrate and clear minor errors.
- Use the TPMS Reset Option (If Available):
- Turn the car to the “On” position without starting the engine.
- Navigate to the TPMS settings on the dashboard screen and select “Reset TPMS.”
- Disconnect the Battery: Disconnecting the car battery for a few minutes, then reconnecting it, can sometimes clear system faults.
Step 3: Identify and Replace Faulty TPMS Sensors
If resetting doesn’t work, one or more sensors may be faulty. Here’s how to check and replace them:
- Use a TPMS Tool or Visit a Mechanic: Many auto shops or TPMS tools can scan each tire’s sensor to find the faulty one.
- Check Sensor Battery Life: If your Taurus is older, the sensor battery might be dead, requiring a replacement.
- Replace the Faulty Sensor: If the tool indicates a faulty sensor, replacing it is necessary. Ensure the replacement sensor is Ford-compatible to avoid further issues.
Step 4: Relearn the New Sensor (If Replaced)
When a TPMS sensor is replaced, the Ford Taurus needs to recognize it through a relearn procedure:
- Initiate Relearning Mode:
- Turn the ignition to the “On” position without starting the car.
- Press and hold the TPMS reset button (if your Taurus has one) or follow your manual’s instructions to start the relearn process.
- Follow On-Screen Instructions: The Taurus will guide you to train each sensor in sequence. Once complete, the system should recognize the new sensor, and the warning should clear.
Additional Tips for Ford Taurus TPMS Care
- Seasonal Changes: Temperature drops can trigger low-pressure warnings. Check your tires regularly, especially in colder months.
- Maintenance During Tire Rotations or Changes: After rotating or changing tires, check that the sensors are correctly re-calibrated.
- Consistent PSI: Maintaining the recommended PSI can help prevent premature sensor wear and keep TPMS alerts accurate.
