Tire Pressure Monitor Fault
Ford Vehicle
Severity: MinorWhat it means
Tire Pressure Monitor Fault means the TPMS system itself has a problem — not that your tires are low.
A sensor battery has died, a sensor was not relearned after tire rotation, or there is a receiver fault.
Check all tire pressures manually and have the TPMS sensors tested.
Affected Models
- Ford F-150
- Ford Explorer
- Ford Escape
- Ford Edge
- Ford Fusion
- Ford Bronco
- All Ford vehicles (2008+)
Common Causes
- TPMS sensor battery dead (lasts 5-10 years)
- Sensor not relearned after tire rotation or new tires
- TPMS receiver module fault
- Aftermarket wheels without TPMS sensors
- Sensor damaged during tire mounting
How to Fix It
-
Manually check all four tire pressures with a gauge.
The TPMS fault means the system is not working — you cannot rely on it.
Check pressures manually until the system is fixed. -
If tires were recently rotated: the sensors may need relearning.
Some Ford models require a relearn procedure after tire rotation.
A tire shop or dealer can perform this with a TPMS tool. -
Have the TPMS sensors tested.
Most tire shops can test TPMS sensors with a handheld tool.
Dead batteries are the most common cause — sensors must be replaced. -
Replace dead sensors.
TPMS sensors cost $30-$80 each.
The tire must be dismounted to replace the sensor.
Frequently Asked Questions
What is the difference between TPMS warning and TPMS fault?
TPMS warning (solid light): a tire is low on pressure.
TPMS fault (flashing then solid): the TPMS system itself has a problem.
How long do TPMS sensor batteries last?
5-10 years depending on driving habits.
The battery is sealed inside the sensor and cannot be replaced — the entire sensor must be replaced.
