5. Installation Instructions

Professional installation is highly recommended. The following steps outline the general procedure for TPMS sensor removal and installation. Refer to your vehicle's service manual for specific details.

TPMS Sensor Removal:

1. Remove Valve Core: Remove the valve core to allow all air to escape from the tire. Discard the old valve core.
2. Remove Mounting Nut (Clamp-in sensors): If applicable, remove the mounting nut from the stem, allowing the sensor to fall into the wheel/tire assembly. Discard the old nut.
3. 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.
4. Mark Sensor Location (if band-mounted): If a band-mounted sensor is present, mark its location on the tire prior to removal. Position the tire/wheel assembly so the sensor is at the 6 and 12 o'clock positions when breaking the bead.
5. Dismount Tire: Liberally lubricate the bead. Position the wheel assembly so the mount/demount head is slightly ahead of the sensor (or the mark on the sidewall if band-mounted). Dismount the tire without contacting or damaging the sensor.
6. Inspect Sensor: Remove the sensor and inspect for damage or tire sealants. Replace the sensor if necessary. If re-installing, clean the sensor thoroughly.
7. Remove Old Rubber Valve Stem (Snap-in sensors): Use a 20140 tool to remove the old rubber valve stem from the back of the sensor. Then, use a standard TTV tool to pull the old rubber valve stem through the hole and discard.

TPMS Sensor Installation:

1. New Components (Clamp-in sensors): When installing a clamp-in sensor, always use a new grommet, mounting nut, special nickel-plated valve core, and sealing cap. NEVER RE-USE OLD COMPONENTS.
2. Insert Sensor (Clamp-in sensors): Insert the sensor through the rim hole with the flat side of the sensor facing toward the wheel. Tighten the mounting nut to the specified torque as defined in the Schrader TPMS Application Guide, using the 20142 Mounting Nut Torque Tool.
3. Assemble Snap-in Sensor: For snap-in sensors, attach a TTV tool to the valve stem. Insert the valve into the sensor body, aligning the flats on the brass stem to the flats on the receiving hole of the sensor body. Use a valve pull tool to prevent the valve from spinning. Use the T-10 tool to assemble the valve to the sensor body before inserting the assembly into the wheel rim hole. NEVER RE-USE OLD COMPONENTS.
4. Install Sensor into Wheel: Use a standard TTV tool to pull the stem straight through the rim hole. To avoid damaging the stem and/or sensor, a rubber mallet or similar device may be placed between the tool and rim flange to ensure the valve is pulled straight.
5. Mount Tire: Position the rim so 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.

CAUTION: DO NOT re-use the removed valve core. Always replace with a new electroless nickel-plated valve core (aluminum stem). Use of non-electroless nickel-plated cores with aluminum valve stems can result in galvanic corrosion and loss of tire pressure. 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

Before beginning installation and vehicle relearn, verify application fitment. 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 through a "re-learning" process.

Driving Relearn Procedure:

1. Activate parking brake. Adjust tires to vehicle placard pressure.
2. Insert key, turn ignition ON (engine off), and then OFF.
3. Exit vehicle and allow to sit for 15 minutes.
4. 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.

OBDII Relearn Procedure (with compatible scan tool):

To avoid driving the vehicle, an OBDII relearn is possible with some OBDII TPMS scan tools:

1. Activate parking brake. Adjust tires to vehicle placard pressure.
2. 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.
3. Turn ignition to ON (engine off). Connect the OBDII cable to the vehicle's OBDII port and the TPMS scan tool.
4. When the OBDII connection is made, the scan tool will display that sensor IDs are uploading (or similar). The process may take up to 1 minute.
5. If the OBDII procedure fails (not all TPMS scan tools are capable), the vehicle must be driven to complete the relearn process.

7. Operating Principles of TPMS

The Tire Pressure Monitoring System (TPMS) continuously monitors your vehicle's tire pressure and alerts you if a tire pressure falls 25% below the recommended inflation. This system is crucial for safety and vehicle performance.

How Direct TPMS Works:

TPMS sensors are installed in each wheel and send pressure information to a receiver located in your vehicle. When the system detects low tire pressure or a malfunction, it causes the TPMS indicator light to appear on your dashboard.

TPMS Light Indicators:

• 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). Solution: Add air to meet placard recommendation.
• Flashing Light: If your TPMS light comes on and flashes for 60-90 seconds before staying solid, it indicates a system malfunction, such as a dead sensor battery, a missing sensor, or an incorrect sensor for the vehicle type. Solution: Replace sensor, relearn sensor.

Benefits of TPMS:

• Safety: Prevents blowouts and flat tires by alerting to low pressure.
• Saves Money: Properly inflated tires reduce tire wear and improve fuel efficiency.
• Keeps You Safe: Reduces the risk of vehicle crashes caused by underinflated tires.
• Improves Car Performance: Proper tire pressure optimizes traction, handling, steering, stability, and braking.
• Reduces CO2 Emissions: Improved fuel economy leads to reduced carbon emissions.

8. Maintenance and Troubleshooting

Step-by-Step Best Practices in TPMS:

1. Check for the Light: Observe the TPMS indicator light during vehicle start-up. It should illuminate briefly and then disappear. If it remains solid or flashes, there's an issue.
2. Inspect Valve Caps: Missing or improper valve caps can lead to corrosion and limit sensor serviceability. Always ensure a sealing valve cap is installed.
3. Check TPMS Sensors: Use a TPMS scan tool to test each installed sensor. This confirms alerts from the dashboard.
4. Access Vehicle's Computer: Use a TPMS scan tool to check for Diagnostic Trouble Codes (DTCs) related to the TPMS system. This helps view sensor history and identify system faults.
5. Review Audit Report: After service, request a detailed audit report. This report shows the status of the TPMS system, including notes on physical inspection and service recommendations.

Types of TPMS Sensors and Serviceable Parts:

TPMS sensors typically come in two main types: Snap-In (with a rubber valve) and Clamp-In (with an aluminum valve). Compression forces, high temperatures, and corrosion can damage components like valve caps, cores, nuts, and grommets. It is crucial to replace these serviceable parts whenever a tire is removed from the wheel to prevent slow tire leaks and ensure proper TPMS function.

9. User Tips

• Verify Fitment: Always confirm the OE number (part number) before purchasing and ensure it matches your original parts. If unsure, contact the seller or a professional.
• Professional Installation: While sensors are pre-programmed, installation and activation (relearn) are best performed by trained professionals to ensure correct function and avoid damage.
• Correct Scan Tool: For OBDII relearn procedures, ensure you use the correct scan tool compatible with your vehicle's make and model.
• Regular Checks: Periodically check your tire pressure manually and be aware of your TPMS indicator light behavior.
