How to Tell Which TPMS Sensor is Bad?

TPMS Sensor

If your car’s tire pressure monitoring system (TPMS) is giving you trouble, it may be time to replace one or more of the sensors. How do you know which sensor is bad, and how do you go about replacing it? In this article, we will walk you through the process of diagnosing TPMS problems and replacing TPMS sensors.

How to Spot a Faulty TPMS Sensor?

The first step is to check the air pressure in all your tires. If one or more of the tires is low on air, then you will need to add air to that tire. The TPMS sensor for that tire should reset after it has been inflated to the right pressure. If the TPMS system does not reset after inflating the low tire, there is a problem with the sensor for that tire.

If all of your tires are properly inflated, the next step is to check the TPMS sensors. You can do this by using a TPMS service tool or disconnecting the battery for about five minutes. Once you have reset the TPMS system, drive around and see if the light comes back on. If it does, then one of the sensors is probably bad. At this point, you will need to remove the bad sensor and replace it with a new one.

How to Replace the TPMS Sensors?

Once you have located the bad sensor, you will need to remove it and install the new sensor. The process for doing this will vary depending on your vehicle, so consult your owner’s manual or a service manual for specific instructions. In general, however, you will need to use a special tool to remove the old sensor from the tire valve, and then you will need to use the same tool to install the new sensor.

Once the new sensor is in place, you should be able to drive around without any TPMS problems. In addition, you should also have a working knowledge of how to check and reset the TPMS system if necessary. This will come in handy if you ever have to replace a TPMS sensor again.

To Conclude

If your TPMS system is giving you trouble, don’t despair. With a little patience and some basic mechanical knowledge, you should be able to diagnose and fix the problem yourself. And if you’re not sure what you’re doing, there’s no shame in taking your car to a professional for help. Either way, you’ll be back on the road in no time.
