433 MHz TPMS Tire Pressure Sensor 20964159 For Buick Cadillac Chevrolet GMC

This TPMS sensor is cross-referenced with the following OEM part numbers and equivalents:

Note: 20964159 is reportedly a discontinued part number. The alternate numbers listed above may serve as suitable replacements. Always verify your original sensor part number and confirm compatibility with your specific vehicle before purchasing.

This TPMS sensor is compatible with a broad range of vehicles. Below is a comprehensive compatibility list:

This OE part number is also compatible with vehicles from:

• HSV (Holden Special Vehicles) – Senator Signature: 2013 – 2017
• Hummer
• Pontiac
• Saturn

Note: This sensor may also be compatible with additional vehicle models not listed above. Always verify your original sensor part number and confirm compatibility with your specific vehicle before purchasing.

When the TPMS sensor begins to fail or its battery reaches the end of its service life, drivers may experience one or more of the following symptoms:

The most common indicator of a failing sensor is the persistent illumination of the TPMS warning light on the dashboard. If tire pressures are confirmed to be correct and the light remains on, the sensor itself is likely the issue.

A TPMS warning light that blinks when the ignition is turned on (bulb check) or flashes persistently indicates a problem with one or more sensors. This could be due to a low battery, a damaged sensor, or a faulty connection.

The tire pressure display on the instrument cluster may show incorrect values, fail to update, or display dashes (—) instead of pressure readings.

The TPMS system may work intermittently, with the warning light turning on and off randomly during driving. This often indicates a weak sensor battery or internal component degradation. There is a known Technical Service Bulletin (TSB) stating that short range problems can be caused by the coaxial cable being disconnected at the rear window antenna, amplifier, or RCDLR.

The system may trigger warnings even when tire pressures are correct, or show inconsistent readings—or no readings at all.

The vehicle's display may show a specific alert indicating a tire pressure monitoring system malfunction, warning the driver that the system is not operating correctly.

Sensors can fail due to battery depletion, damage from road debris, or corrosion. Valve stem corrosion is a frequent issue, especially in areas that use road salt during winter.

The sensor is equipped with an automotive-grade battery with an expected service life of 4 to 10 years under normal operating conditions. The battery is non-replaceable, meaning the entire sensor unit must be replaced when the battery is depleted.

Before purchasing, confirm that your vehicle's original sensor carries part number 20964159. This number can typically be found:

• Printed on the sensor body itself
• In the vehicle's service documentation
• Through the vehicle manufacturer's parts catalog

Note: 20964159 is reportedly a discontinued part number. The following alternate numbers are known to interchange: 13581559, 13598726, 13598786. Always verify compatibility before purchasing.

This sensor primarily operates at 315 MHz, with a 433 MHz variant also available. Verify which frequency your vehicle's TPMS system requires before purchasing.

Important: This sensor requires proper installation and may require programming for vehicle integration. Key points to consider:

• Pre-programmed Options: Some TPMS sensors come pre-programmed for your specific make, model, and year, allowing for quick and easy replacement.
• Manual Relearn Required: This sensor typically requires a manual relearn procedure using a TPMS scan tool. The relearn procedure for this sensor follows the same process as the vehicle's learn procedure.
• Two Ways to Program: Create a new ID and use any diagnostic tool to relearn a vehicle. Alternatively, manually enter an existing OE sensor ID and skip the relearn process altogether.
• Professional Installation: Installation of TPMS sensors is recommended to be performed by trained professionals. Tire installation specialists should be aware of the sensor's presence to avoid damage during tire mounting and demounting procedures.

This sensor is supplied with a clamp-in metal valve stem. Key considerations:

• Nickel-coated finish
• OE style construction
• Hardware included

Sensors can be replaced individually as they fail, or as a complete set of four. The choice depends on:

• The age of the remaining sensors (if approaching 4–10 years, consider full set replacement)
• Budget considerations
• The specific failure pattern (single sensor vs. multiple failures)

This sensor is designed for any wheel position and does not require position-specific programming. The vehicle's TPMS system will automatically learn which sensor is at which wheel position after driving.

The sensor is designed to withstand extreme operating conditions:

• Operating Temperature: -40°C to +125°C
• Storage Temperature: -40°C to +35°C
• Operating Humidity: ≤90%

When purchasing replacement sensors:

• Choose sensors that meet or exceed OEM specifications
• Ensure the sensor is supplied new and in original packaging
• Confirm the sensor includes the appropriate valve stem configuration
• Look for sensors that have undergone rigorous testing

After installation:

• If using a TPMS scan tool, perform the manual relearn procedure as outlined by the vehicle manufacturer
• Drive the vehicle to allow the sensor to communicate with the TPMS receiver
• Monitor the TPMS display to confirm pressure readings are appearing correctly
• If the warning light persists, a diagnostic scan may be required to identify any remaining issues. Check for potential issues such as the coaxial cable being disconnected at the rear window antenna, amplifier, or RCDLR

When ordering this sensor, provide the following vehicle information to ensure correct compatibility:

• Make and model
• Year of production
• Target market (as frequencies may differ by region)
