Sensor Battery Issues
TPMS sensors are powered by small batteries. These batteries typically last for several years, but they do eventually die. A dead battery in a sensor can lead to inaccurate readings or a complete loss of signal. Unfortunately, you can’t just replace the battery; the entire sensor unit needs replacing when the battery dies. This is a normal part of TPMS maintenance. A mechanic can confirm a dead sensor battery by checking the sensor signal with a diagnostic tool.
Signal Interference
Various factors can interfere with the TPMS signal transmission between the sensors and your car’s receiver. Some common culprits include electronic devices like radar detectors, GPS units, and even some cell phone chargers. Metallized window tint can also block TPMS signals. Try temporarily removing or disconnecting any such devices to see if the problem resolves. If the problem persists, check your tint to see if it is metallized.
Incorrect Sensor Programming/Relearn
After rotating your tires or replacing a sensor, the system needs to “relearn” the position of each sensor. If this relearn procedure isn’t performed correctly, the system might display incorrect pressure readings or fail to register a sensor altogether. Each car model has a specific relearn procedure, so consult your owner’s manual for the proper steps. Some vehicles require a special tool, while others have a built-in relearn process that can be initiated through the car’s menu system or by driving a specific pattern.
Faulty TPMS Receiver
While less common, the receiver module in your car that picks up the TPMS signals could malfunction. This is less likely than a sensor issue, but it’s a possibility. A diagnostic tool is needed to check the receiver module’s functionality.
Damaged Sensors
Physical damage to a sensor, perhaps during tire mounting or from road debris, can also cause it to malfunction. Inspect your tires and wheels for any visible damage to the sensors. They’re usually located behind the valve stem. Damaged sensors need to be replaced.
Extreme Temperatures
Extremely cold temperatures can sometimes temporarily affect TPMS sensor readings. The lower air pressure in cold weather can be misinterpreted by the sensors, triggering a false low-pressure warning. Once the tires warm up, the pressure typically returns to normal, and the warning light should go off. However, if the light stays on, it’s worth double-checking your tire pressure with a reliable gauge.
Using Incompatible Tire Sealants
Some tire sealants can coat the TPMS sensor, interfering with its operation. If you’ve recently used a tire sealant and are experiencing TPMS issues, the sealant could be the culprit. Consult your owner’s manual or a tire professional to ensure you’re using a TPMS-compatible sealant.
Low Tire Pressure (Actual Low Pressure)
Sometimes the simplest explanation is the correct one. Before troubleshooting more complex issues, verify your tire pressure with a reliable gauge. It’s easy to overlook the obvious. Inflate your tires to the recommended pressure listed on the sticker typically located on the driver’s side doorjamb or in your owner’s manual.
