Quick AnswerMost TPMS warnings on these vehicles come from low tire pressure, a dead sensor battery, a sensor that lost its learned ID, or RF interference—not automatically a failed wheel sensor. Check pressures first, then use a TPMS scan tool to read sensor IDs, activation response, and 433MHz signal consistency before replacing parts.
Start With Pressure and Scan Data
A solid TPMS light usually points to low pressure or a stored pressure warning. A light that flashes for roughly a minute and then stays on often indicates a sensor or communication fault. Inflate tires to the cold-pressure spec on the door placard, drive briefly, and see whether the light clears. If it returns with correct pressure, scan all four sensors.
Look for one wheel with no ID, no activation response, weak signal, or repeated dropouts. Do not replace the TPMS module until the sensor data proves the module is the problem.
Dead Sensor Battery Symptoms
TPMS batteries are sealed inside the sensor, so a
