1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of the SAE TRW 42607-0C070 Tire Pressure Monitoring System (TPMS) sensors. These sensors are designed to monitor tire pressure and transmit data to your vehicle's onboard system, alerting you to under-inflated tires. Adherence to these instructions is crucial for optimal performance and safety.
2. Product Overview
The SAE TRW 42607-0C070 TPMS sensor kit includes four individual tire pressure sensors and associated service components. Each sensor is a critical part of your vehicle's safety system, designed to provide accurate tire pressure readings. The sensors are pre-programmed for specific vehicle models and operate at a frequency of 315 MHz.

3. Compatibility
These TPMS sensors are compatible with the following Toyota vehicle models and years:
- Toyota Sequoia: 2008, 2009, 2010, 2011, 2012, 2013
- Toyota Sienna: 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014
- Toyota Tundra: 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014
Verify your vehicle's make, model, and year against this list to ensure proper fitment. Consult your vehicle's owner's manual or a qualified technician if you are unsure about compatibility.
4. Package Contents
Each SAE TRW 42607-0C070 TPMS sensor kit typically includes:
- 4 x TRW 42607-0C070 TPMS Sensors
- 4 x Service Kits (including valve stems, caps, nuts, and washers)
5. Safety Information
Warning: Installation of TPMS sensors involves working with vehicle tires and wheels. Improper installation can lead to tire damage, sensor malfunction, or serious injury. It is highly recommended that installation be performed by a certified automotive technician using appropriate tools and safety procedures.
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure the vehicle is properly supported on a lift or jack stands before removing wheels.
- Follow all tire manufacturer and vehicle manufacturer guidelines for tire removal, mounting, and balancing.
- Do not attempt to disassemble the TPMS sensor.
6. Setup and Installation
The installation of TPMS sensors requires specialized tools and knowledge. Professional installation is strongly advised.
General Installation Steps:
- Prepare Vehicle: Safely lift the vehicle and remove the wheels.
- Deflate Tire: Completely deflate the tire.
- Break Bead: Break the tire bead from the rim using a tire changing machine.
- Remove Old Sensor: Carefully remove the old TPMS sensor from the wheel. This usually involves unscrewing a retaining nut and pushing the sensor through the valve stem hole.
- Install New Sensor: Insert the new SAE TRW 42607-0C070 sensor through the valve stem hole from the inside of the rim. Ensure the sensor body is correctly oriented within the tire. Secure it with the new retaining nut, tightening to the manufacturer's specified torque (typically 4 Nm or 35 in-lbs).

- Mount Tire: Mount the tire back onto the rim, taking care not to damage the sensor.
- Inflate Tire: Inflate the tire to the vehicle manufacturer's recommended pressure.
- Balance Wheel: Balance the wheel and tire assembly.
- TPMS Relearn Procedure: After installation, the new sensors must be registered with the vehicle's TPMS control module. This typically involves a 'relearn' procedure, which varies by vehicle model. Common methods include:
- Automatic Relearn: Driving the vehicle for a certain period at a specific speed.
- Manual Relearn: Following a sequence of steps using the vehicle's dashboard controls.
- OBD-II Relearn: Using a specialized TPMS scan tool to program the sensor IDs into the vehicle's computer.
- Verify Operation: After the relearn procedure, ensure the TPMS warning light on the dashboard is off and tire pressures are displayed correctly (if your vehicle has this feature).
7. Operating Instructions
Once properly installed and relearned, the SAE TRW 42607-0C070 TPMS sensors will continuously monitor your tire pressures. If a tire's pressure drops below a predetermined threshold (typically 25% below the recommended pressure), the TPMS warning light on your dashboard will illuminate. This indicates a significant loss of tire pressure in one or more tires.
What to do if the TPMS light illuminates:
- Safely Pull Over: Reduce speed and pull over to a safe location as soon as possible.
- Check Tire Pressures: Manually check the pressure of all four tires using a reliable tire pressure gauge.
- Inflate Tires: Inflate any under-inflated tires to the vehicle manufacturer's recommended pressure (found on a sticker inside the driver's side door jamb or in the owner's manual).
- Drive Vehicle: After adjusting pressures, drive the vehicle for a short period (e.g., 10-20 minutes at 25 mph or higher) to allow the system to update and the light to turn off.
- Seek Professional Help: If the light remains on after adjusting pressures and driving, or if it flashes, there may be a system malfunction. Consult a qualified technician.
8. Maintenance
TPMS sensors are generally maintenance-free, but certain practices can prolong their lifespan and ensure accurate readings:
- Regular Tire Pressure Checks: Even with TPMS, manually check your tire pressures monthly.
- Service Kit Replacement: When tires are replaced or serviced, it is recommended to replace the TPMS sensor service kit components (valve stem, cap, nut, washer) to prevent leaks and corrosion.
- Battery Life: TPMS sensors are powered by internal batteries that typically last 5-10 years. When a sensor battery dies, the sensor will stop transmitting, and the TPMS warning light will illuminate. The sensor must be replaced as the battery is not serviceable.
- Avoid Tire Sealants: Some tire sealants can damage TPMS sensors. Consult the sealant manufacturer's instructions regarding TPMS compatibility.
9. Troubleshooting
If you experience issues with your TPMS system after installing the SAE TRW 42607-0C070 sensors, consider the following:
- TPMS Light Remains On After Inflation: Ensure the relearn procedure was completed correctly for your vehicle. Drive the vehicle for an extended period to allow the system to reset. If the issue persists, a sensor may be faulty or not properly programmed.
- TPMS Light Flashes: A flashing TPMS light typically indicates a system malfunction, not just low pressure. This could be a dead sensor battery, a damaged sensor, or an issue with the vehicle's TPMS control module. Professional diagnosis is required.
- Incorrect Pressure Readings: Verify readings with a known accurate tire pressure gauge. If discrepancies exist, the sensor may be faulty or the relearn procedure was incomplete.
- Sensor Not Detected: This can occur if the sensor was not properly installed, is faulty, or if the relearn procedure failed.
For persistent issues, it is recommended to consult a certified automotive technician with TPMS diagnostic capabilities.
