2. Setup and Installation
2.1 Important Safety Warnings and Cautions
- Professional Installation Only: These TPMS sensor assemblies are replacement or maintenance parts for motor vehicles that have a factory-installed TPMS only. Failure to follow installation instructions may result in the failure of the motor vehicle TPMS sensor to operate properly.
- Vehicle Compatibility: Each TPMS sensor is designed to operate in specific motor vehicle makes, models, and years using the proper frequencies (315MHz for this model). Only install sensors designated for your specific vehicle. Improper installation or use of unauthorized sensors will cause the TPMS system to fail.
- Wheel Condition: Do not install TPMS sensors in damaged wheels.
- Original Equipment Wheels/Tires: These sensors are designed to operate in Original Equipment wheels and tires only. If non-OE wheels/tires are used, the TPMS system may not function correctly. It is the vehicle owner's responsibility to ensure the TPMS is working correctly with non-OE components.
- Failure to follow installation instructions or the use of improper TPMS sensors may result in the motor vehicle TPM system failure causing property damage, personal injury, or death.
2.2 Installation Process
The following steps outline the general procedure for TPMS sensor removal and installation. Refer to your vehicle's service manual for specific details.

Figure 2: TPMS Sensor Removal and Installation Guide
- Remove Valve Core: Remove the valve core to allow all air to escape. Discard the old valve core.
- Removing a Clamp-in Sensor Before Dismount: Remove the mounting nut from the stem and allow the sensor to fall into the wheel/tire assembly. Discard the old nut.
- With Sensor Removed: 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.
- With Sensor Installed (Band Mounted): Locate and mark the sensor's position on the tire. Position the Tire/Wheel Assembly so the sensor is at 6 and 12 o'clock positions when breaking the bead.
- With Sensor Installed (Tire Removal): Liberally lube the bead. Position the wheel assembly so the mount/demount head is slightly ahead of the sensor. The tire should dismount without contacting the sensor. Repeat for the bottom bead.
- Sensor Inspection: Remove the sensor and inspect for damage. If reusing, clean thoroughly.
- Snap-in Sensor Removal: Remove T-10 screw from back of sensor. Use a standard TTV tool to pull old rubber valve stem through the hole.
- Installing a Clamp-in Sensor: Use a new grommet, mounting nut, special nickel-plated valve core, and sealing cap. Insert the sensor through the rim hole with the flat side facing the wheel. Tighten the mounting nut to the specified torque (e.g., 10 Nm).
- Assembling a Snap-in Sensor: Attach TTV tool to valve stem. Insert the valve into the sensor body aligning the flats. Use a T-10 tool to assemble the valve to the sensor body.
- Installing Snap-in Sensor into Wheel: Use a standard TTV tool to pull the stem straight through the rim hole. A rubber mallet can be used between the tool and rim flange.
- Tire Installation: Position the rim so the sensor is 90° or ¼ turn to the right of the mount/demount head. Liberally lubricate tire beads. Maintain pressure on the tire between the sensor's starting point and the mount/demount head to keep the bead in the drop center of the wheel.
- Valve Core Caution: 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!
Note: The Tire Pressure Sensor is 100% new and comes pre-programmed specifically for your vehicle. It needs to be activated by a scan tool or "re-learning" procedure.
3. Operating Instructions
3.1 Vehicle Relearn Procedure
After installing new TPMS sensors, the vehicle's system must be relearned to recognize the new sensor IDs. There are two common methods:
Method 1: Driving Relearn
- 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 (with compatible scan tool)
- 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 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).
3.2 Understanding TPMS Indicator Lights
Your vehicle's TPMS indicator light on the dashboard provides important information about your tire pressure system.
- Solid Light: If the TPMS light comes on and stays solid, it indicates that one or more tires have low air pressure (typically 20% below recommended placard pressure). Add air to the tires to meet the placard recommendation.
- Flashing Light: If the TPMS light comes on and flashes for 60-90 seconds before staying solid, it indicates a system malfunction. This could be due to a dead sensor battery, a missing sensor, a broken sensor, or an incorrect sensor for the vehicle type.
4. Maintenance
Regular maintenance of your TPMS sensors and related components ensures optimal performance and safety.
- Inspect Valve Caps: A missing or improper valve cap can lead to corrosion, limiting the serviceability of a TPMS sensor. Always ensure a sealing valve cap is installed. Avoid chrome-plated plastic caps, non-sealing caps, and vanity caps.
- Check TPMS Sensors: Periodically, use a TPMS scan tool to test each installed sensor. This helps confirm proper function, especially if the indicator light has been active.
- Replace Serviceable Parts: Compression forces, high temperatures, and corrosion can damage TPMS components (grommets, nuts, valve cores). These parts should be replaced anytime a tire is removed from the wheel to prevent slow tire leaks. Never reuse old valve cores; always replace with a new electroless nickel-plated valve core.
5. Troubleshooting
If you experience issues with your TPMS, consider the following troubleshooting steps:
- Flashing TPMS Light: As noted in the Operating section, a flashing light indicates a system malfunction. This requires further investigation.
- Access Vehicle's Computer: Use a TPMS scan tool to check for any Diagnostic Trouble Codes (DTCs) related to the vehicle's TPMS system. This can help identify specific system faults. You can also view sensor history.
- Review Audit Report: After any service on the TPMS, a detailed "audit report" from a scan tool should be provided. This report shows the status of the TPMS system and can include service recommendations.
- Re-check Installation: If issues arise after installation, re-verify all installation procedures, especially torque specifications for mounting nuts and valve cores.
