TPMS Warning Light
One of the first signs of a tire sensor fault is the TPMS warning light illuminating on your dashboard. This light comes on when the tire pressure monitoring system detects an issue with tire pressure or the sensor itself. Common reasons for this include:
- Sensor malfunction:
The sensor may be faulty, unable to read the pressure correctly, or not transmitting data to the car’s computer. - Low tire pressure:
Tires that are underinflated due to leaks or temperature changes can trigger the warning light. - Wiring or control module issues:
Problems with the system’s wiring or control module can also cause the TPMS light to turn on, as these components are crucial for proper communication between the sensors and the onboard system.
Tire Pressure Warning Message
Another symptom of a tire sensor fault is a tire pressure warning message appearing on the instrument cluster or dashboard display. This message is designed to inform the driver that the tire pressure is too low or that the TPMS is malfunctioning. Depending on the fault, the message may:
- Specify which tire has low pressure.
- Indicate a general problem with the TPMS system itself. In either case, this warning should prompt immediate action, such as checking tire pressure or inspecting the TPMS for potential faults.
Inconsistent Tire Pressure Readings
A faulty tire sensor can cause inconsistent or fluctuating tire pressure readings. You may notice that your vehicle’s computer displays different pressure levels each time you check, even if the tires have not been adjusted. This inconsistency can be caused by:
- Faulty sensors:
The sensor may be damaged, preventing it from accurately reading tire pressure. - Weak or dead sensor batteries:
Sensor batteries typically last around 5-10 years, and a weak battery can lead to incorrect or erratic pressure readings. - Physical damage:
A damaged sensor housing from road debris or corrosion can result in inaccurate readings, leading to potential safety hazards.
Persistent Low Tire Pressure Warnings
Even after properly inflating your tires to the recommended levels, you may still encounter persistent low tire pressure warnings. This ongoing issue can be frustrating for drivers, but it typically indicates:

Some drivers may notice that the TPMS warning light or message appears randomly or only at certain times, such as during extreme temperature changes. This may point to a weak sensor battery or sensor degradation over time. - Unresponsive Sensors:
In rare cases, a sensor may stop working entirely, causing the system to fail to detect changes in tire pressure altogether. This can result in a complete lack of alerts, leaving the driver unaware of potentially unsafe tire conditions.
Causes of Ford Explorer Tire Sensor Fault
Several factors can contribute to a tire sensor fault in a Ford Explorer. Understanding these causes is crucial for effective diagnosis and repair. Here are the primary reasons why the tire pressure monitoring system (TPMS) might malfunction:
Sensor Battery Failure
One of the most common causes of tire sensor faults is sensor battery failure. Each tire pressure sensor contains a small battery that powers the device, allowing it to monitor tire pressure and transmit data to the car’s computer. Over time, these batteries degrade and eventually fail, typically lasting between 5 to 10 years. Once the battery weakens or dies, the sensor can no longer function properly, resulting in:
- Inconsistent or inaccurate tire pressure readings.
- TPMS warning light activation on the dashboard.
- Intermittent or total loss of signal from the sensor.
Replacing the sensor battery is often necessary to restore full functionality, although some sensors may require complete replacement depending on the model.
Physical Damage to Sensors
Physical damage is another major cause of tire sensor faults. Since tire sensors are located inside the wheel, they are vulnerable to impact and wear from everyday driving conditions. Common ways sensors can be damaged include:
- Road debris:
Rocks, gravel, or other debris kicked up from the road can hit the valve stem or sensor, causing damage. - Corrosion:
Over time, moisture and dirt can corrode the metal parts of the sensor, particularly around the valve stem. This corrosion can prevent the sensor from accurately measuring tire pressure or communicating with the vehicle’s system. - Improper tire installation or repair:
Sensors can be accidentally damaged during tire installation or when changing a flat tire if the technician is not careful.
Inspecting sensors for visible damage, corrosion, or debris buildup is important when diagnosing a sensor fault.
Faulty TPMS Control Module or Wiring
The TPMS control module and wiring act as the communication hub between the tire sensors and the vehicle’s onboard computer. If there is an issue with the control module or wiring, it can prevent the system from receiving accurate readings from the sensors. Problems with the module or wiring may occur due to:
- Wiring faults:
Loose, damaged, or corroded wiring connections can disrupt communication between the sensors and the TPMS system, leading to inaccurate readings or system failure. - Control module failure:
