Q: Faulty low air pressure sensor.

asked by on January 11, 2016

My low air pressure sensor is on, even though the tire pressure is okay.

The tire pressure monitoring system will only trigger a warning light for three reasons including a low tire pressure. The other two reasons are if the computer does not detect a signal from a sensor due to it being missing or if a sensor has a low battery. Assuming that all of your sensors are still present the most likely cause is a low battery in one of the sensors. Unfortunately, these batteries are not replaceable and the whole sensor must be replaced to correct the issue. I would recommend taking your vehicle to a place that services tires as these sensors can be very difficult to replace without a tire mounting machine. I would not attempt to replace a sensor on your own. Have a mechanic inspect the problem before you have the sensor replaced to make sure that you are not replacing anything unnecessary.
