2. Stationary (Manual)

The stationary or manual method involves using a TPMS tool or scanner to manually program the sensors. This method is more common in older vehicles or vehicles that do not support auto relearn.

3. OBD (On-Board Diagnostics) Relearn

The OBD relearn method uses the vehicle’s OBD-II port to program the TPMS sensors. A TPMS tool or scanner is connected to the OBD-II port, and the tool communicates with the vehicle’s computer to program the sensors.

Important things to keep in mind:

• Compatibility: Ensure the testing method is compatible with your specific TPMS sensor type and vehicle.
• Accuracy: Pre-installation testing doesn’t guarantee 100% performance after installation. Factors like tire mounting and wheel alignment can affect sensor readings.
• Cost: Some dedicated tools or test chambers might incur fees.

Here are some recommendations:

• If buying new sensors: Ask the seller if they provide pre-installation testing.
• For existing sensors: Consider taking them to a tire shop equipped with a TPMS tool for basic functionality check.
• Remember: Pre-installation testing is mainly for confirming the sensor’s basic functionality and not a complete guarantee of perfect performance after installation.

How Do You Test A TPMS Sensor?

Here’s a step-by-step guide on how to test a TPMS sensor effectively and cleanly:

1. Check the Basics First

Ensure that the vehicle’s tires are inflated to the recommended pressure. Check for any visible damage or corrosion on the TPMS sensor, valve stem, or sensor housing.

2. Use a TPMS Diagnostic Tool

Connect a TPMS diagnostic tool to the vehicle’s OBD-II port (usually located under the dashboard).

Battery Check:

TPMS sensors are powered by a battery. If possible, check the battery status of each sensor. Some sensors have a limited battery life, and if they are old or have been in storage for a long time, the battery may be depleted.

3. Check Sensor Data

The diagnostic tool will display data such as tire pressure, temperature, battery status (if the sensor has a battery), and sensor ID.

4. Test Sensor Response

Using the diagnostic tool, send a command to the TPMS sensor to wake it up or request a status update.

5. Test Sensor Signal Strength

Some advanced TPMS diagnostic tools can measure the signal strength of the TPMS sensors. Ensure the signal strength is within the manufacturer’s specified range.

6. Check for Codes

The diagnostic tool can also read and clear TPMS-related fault codes. If any codes are present, address the issues accordingly.

7. Physical Inspection

Visually inspect the TPMS sensor for signs of damage, moisture ingress, or corrosion. Replace any damaged sensors.

8. Pressure and Temperature Testing

Use a pressure and temperature testing device to simulate different conditions and verify that the sensors accurately report pressure and temperature data.

How To Test TPMS Sensor Battery

To test a TPMS (Tire Pressure Monitoring System) sensor battery:

• Remove the sensor from the tire.
• Use a multimeter to measure the battery voltage.
• Compare the reading to the sensor’s specifications.
• If below spec, replace the battery or the entire sensor.

What Factors Affect TPMS Service?

Several factors can affect TPMS service or its ability to function correctly:

• Battery Life: TPMS sensors are typically battery-powered. Over time, these batteries can wear.
• Sensor Damage: Physical damage to the TPMS sensor can lead to malfunction. 
• Sensor Calibration: After tire rotation, and replacement the TPMS may need recalibration or relearn procedures. If not done correctly, the system might not function accurately.
• Environmental Factors: Extreme temperatures, both hot and cold, can impact TPMS sensor performance. 
• TPMS Receiver or System Malfunction
• Tire Age and Wear: Older tires or tires with uneven wear can sometimes cause false TPMS alerts. 
• Aftermarket Modifications: Installing aftermarket wheels or suspension modifications without considering TPMS compatibility can lead to issues.
• Software Updates: Like other electronic systems in modern vehicles, TPMS software might need updates to address bugs or improve functionality.

When To Replace TPMS Sensor: Verify TPMS Before Tires Hit the Road

Here are some common reasons and signs to consider when determining if it’s time to replace a TPMS sensor:

1. TPMS Warning Light

If the TPMS warning light illuminates on your dashboard and stays on (not just a brief flash upon startup), it could indicate a problem with the TPMS sensor or the system as a whole.

2. Low or Fluctuating Tire Pressure

If one or more of your tires consistently shows low pressure or if the pressure appears to fluctuate without any noticeable punctures or leaks, it could be due to a malfunctioning TPMS sensor.

3. Aging Sensor Batteries

TPMS sensors have batteries that power the sensors. Depending on the sensor’s design, these batteries can last anywhere from 5 to 10 years. Once the battery dies, the sensor typically needs replacement.

4. Physical Damage
