Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
TPMS Reset Procedures
When a tire pressure falls below 25 psi (172 kPa) after the vehicle has been driven about 30 seconds over 25 mph (40 km/h), a pressure switch within the sensor is activated. An electronic signal is transmitted to the receiver/control module, which will illuminate the LOW TIRE PRESSURE warning light and store a diagnostic code for that ignition cycle.
When the LOW TIRE PRESSURE warning light illuminates, adjust tires to the specified pressure. This warning light will remain illuminated until ignition is turned off, even if tires are inflated while vehicle is running.
