Ford Ranger Tire Pressure Monitoring System(TPMS) Reset
The tire pressures are also on the tire inflation pressure label (located on the edge of driver door or the B-Pillar). As a driver assistance feature, your vehicle has a tire pressure monitoring system. A warning lamp will illuminate when one or more of the tires are significantly under-inflated. If the low tire pressure warning lamp illuminates, you should stop your vehicle as soon as it is safe to do so, check the tires and inflate them to the correct pressure. Driving on under-inflated tires can:
•Cause them to overheat.
• Lead to tire failure.
• Reduce fuel efficiency.
• Reduce tire life.
• Affect vehicle handling or stopping ability.
The system is not a substitute for correct tire maintenance. You must maintain the correct tire pressures, even if low tire pressure has not illuminated the warning lamp. The tire pressure monitoring system has a system malfunction indicator to warn you when the system is not operating correctly.
The malfunction indicator and low tire pressure warning lamp have a combined function. When the system detects a malfunction, the warning lamp will flash for approximately one minute and then remain illuminated. This sequence will occur every time you switch the ignition on while the malfunction remains. The system has detected a fault that requires service. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressures. A malfunction may occur for a variety of reasons, including the installation of a replacement tire or wheel that prevents the system from functioning correctly. Always check the tire pressure monitoring system malfunction warning after replacing one or more tires or wheels on your vehicle. Make sure the replacement tires or wheels allow the system to continue to function correctly.
Changing Tires With a Tire Pressure Monitoring System
Note: Each road wheel and tire is fitted with a tire pressure sensor located inside the wheel and tire assembly cavity. The pressure sensor attaches to the valve stem. The tire covers the pressure sensor and it is not visible unless the tire is removed. Take care when changing the tire to avoid damaging the sensor.
