1. Introduction to TPMS
The Tire Pressure Monitoring System (TPMS) is a safety feature designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. It provides real-time tire pressure information to the driver, enhancing safety and fuel efficiency.
Why TPMS is Important:
- Distress Signal: Continuously monitors tire pressure and notifies you if pressure falls 25% below recommended inflation, helping prevent blowouts or flat tires.
- Saves Money: Properly inflated tires reduce tire wear and improve fuel economy.
- Keeps You Safe: Underinflated tires are a significant cause of vehicle crashes.
- Improves Car Performance: Optimal tire pressure enhances traction, handling, steering, stability, and braking.
- Reduces CO2 Emissions: Better fuel mileage translates to reduced carbon emissions.

5. Installation Instructions
This section details the removal of old sensors and installation of new clamp-in type TPMS sensors. Refer to a professional for assistance if unsure.
Tools Required (Not Included):
- Valve core removal tool
- Tire changing machine
- T-10 tool (for snap-in sensors, if applicable)
- Schrader TPMS Application Guide & 20142 Mounting Nut Torque Tool (for clamp-in)
- Standard TTV tool (for snap-in)
- Rubber mallet (for snap-in)
- Approved valve core tool
Sensor Removal (Clamp-in Type):
- Remove Valve Core: Remove the valve core to allow all air to escape. Discard the old valve core.
- Remove Mounting Nut: Remove the mounting nut from the stem and allow the sensor to fall into the wheel/tire assembly. Discard the old nut.
- Break Bead: Bounce the wheel/tire to ensure the sensor has fallen free. Break the bead free from the rim on the shallow side first, then from the deep side.
- Sensor Location (if installed): If a sensor is already installed, locate and mark its position on the tire. Position the Tire/Wheel Assembly so that the sensor is located at 6 and 12 o'clock positions when breaking the bead.
- Tire Removal: Liberally lube the bead and position the wheel assembly such that the mount/demount head is slightly ahead of the sensor. The tire should dismount without coming in contact with and causing damage to the sensor.
- Inspect Sensor: Remove the sensor and inspect for damage. If re-installing, clean and dry the sensor.
Sensor Installation (Clamp-in Type):
CAUTION: NEVER RE-USE OLD COMPONENTS. Always use a new grommet, mounting nut, special nickel-plated valve core, and sealing cap.
- Insert Sensor: Insert the sensor through the rim hole with the flat side of the sensor facing toward the wheel.
- Tighten Mounting Nut: Tighten the mounting nut to the specified torque as defined in the Schrader TPMS Application Guide, using the 20142 Mounting Nut Torque Tool.
- Tire Installation: Position the rim so that the sensor is 90° to the right of the mount/demount head. Liberally lubricate the beads of the tire. While the machine is rotating, maintain pressure on the tire between the starting point of the sensor and the mount/demount head to keep the bead of the tire in the drop center of the wheel. This allows the tire to be installed without damage to the sensor. All tires are mounted with the sensor installed in the wheel.
- Valve Core: DO NOT re-use the removed valve core. Always replace with a new electroless nickel-plated valve core (aluminum stem). Tighten core with an approved valve core tool to 0.23Nm - 0.56Nm (2 in-lbs. - 5 in-lbs.). Do Not Over tighten!
6. Vehicle Relearn Instruction
After installing new TPMS sensors, the vehicle's system needs to learn the new sensor IDs. Verify application fitment before proceeding.
Method 1: Automatic Relearn (Driving)
- Activate parking brake. Adjust tires to vehicle placard pressure.
- Insert key, turn ignition ON (engine off), and then OFF.
- Exit vehicle and allow to sit for 15 minutes.
- For the system to learn new TPMS sensor IDs, the vehicle must be operated for several minutes at a speed of 15 mph (25 kph) or more.
Method 2: OBDII Relearn (Using Scan Tool)
To avoid driving the vehicle, an OBDII relearn is possible with some OBDII TPMS scan tools.
- Activate parking brake. Adjust tires to vehicle placard pressure.
- Follow TPMS scan tool prompts for vehicle application. Trigger the left-front TPMS sensor at the valve stem using the TPMS scan tool trigger. Repeat for remaining sensors in the following order: right-front, right-rear, left-rear.
- Turn ignition to ON (engine off). Connect the OBDII cable to the vehicle's OBDII port and the TPMS scan tool.
- When the OBDII connection is made, the scan tool will display that sensor IDs are uploading (or similar). This process may take up to 1 minute.
- If the OBDII procedure fails (not all TPMS scan tools are capable), the vehicle must be driven to complete the relearn process (Method 1).
7. Operating Principles and Best Practices
TPMS Light Indicator:
- Solid Light: If your TPMS light comes on and stays solid, it indicates that one or more tires have low air pressure (20% below recommended placard pressure).
- Flashing Light: If your TPMS light comes on and flashes for 60-90 seconds before staying solid, it indicates a system malfunction (e.g., dead sensor battery, missing sensor, broken sensor, or incorrect sensor type).
Step-by-Step Best Practices:
- Check for the Light: The TPMS indicator light should illuminate on the dashboard during start-up and then disappear. If it stays solid, add air. If it flashes, replace/relearn sensor.
- Inspect Valve Caps: A missing or improper valve cap can lead to corrosion. Ensure a sealing valve cap is always installed.
- Check TPMS Sensors: Use a TPMS scan tool to test each installed sensor to confirm alerts.
- Access Vehicle's Computer: Use a TPMS scan tool to check for Diagnostic Trouble Codes (DTCs) related to the TPMS system.
- Review Audit Report: After service, provide a detailed "audit report" showing the status of the TPMS system.
8. Maintenance
- Regular Tire Pressure Checks: Even with TPMS, it's good practice to manually check tire pressure periodically.
- Valve Cap Inspection: Regularly inspect valve caps for damage or loss. Replace any missing or damaged caps with proper sealing valve caps to prevent corrosion and debris entry.
- Sensor Replacement: TPMS sensors have batteries with a finite lifespan (typically 5-10 years). If a sensor battery dies, the entire sensor unit must be replaced.
- Professional Servicing: When tires are serviced (e.g., rotated, replaced), it is recommended to have the TPMS sensors inspected and serviced by a professional. Compression forces, high temperatures, and corrosion can damage sensor components. Serviceable parts (grommets, nuts, valve cores) should be replaced anytime a tire is removed from the wheel.
9. Troubleshooting
If your TPMS light illuminates or you suspect a problem, follow these steps:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Solid TPMS Light | One or more tires are underinflated (20% below recommended pressure). | Add air to all tires to meet placard recommendations. Drive for a few minutes; light should turn off. |
| Flashing TPMS Light (then solid) | System malfunction: dead sensor battery, missing sensor, broken sensor, or incorrect sensor for vehicle type. | Replace the faulty sensor(s) and perform a vehicle relearn procedure. Consult a professional if unsure. |
| TPMS Light remains on after tire pressure adjustment/sensor replacement | Vehicle has not completed the relearn process or there's another system fault. | Ensure the vehicle relearn procedure (driving or OBDII) has been completed successfully. If the light persists, use a scan tool to check for DTCs or consult a professional. |
| Inaccurate pressure readings | Faulty sensor, incorrect sensor type, or interference. | Verify sensor compatibility. Replace suspected faulty sensor. Ensure proper installation. |
10. User Tips
