TPMS Mercedes Tire Pressure Sensor 407009322R For FIAT LADA Nissan Opel Vauxhall

407009322R TPMS Tire Pressure Sensor For Dacia / FIAT / LADA / Mercedes-Benz / Nissan / Opel / Vauxhall / Smart

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

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:

• ALFA ROMEO

• CHEVROLET

• LANCIA

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 constantly flashing TPMS light (typically for 60 to 90 seconds upon startup) 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. Loss of radio signal from one or more sensors will cause the TPMS light to come on again.

The most common TPMS warning messages include:

• "Tyre press. monitor inoperative"

• "Tyre pressure monitor inoperative"

• "Tire pressure monitor inoperative"

• "No wheel sensors"

Sensors can fail due to battery depletion, damage from road debris, or corrosion. Harsh driving conditions, potholes, or improper tire changes can damage the sensors, leading to malfunctions. 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 6 years under normal operating conditions. The battery is non-replaceable, meaning the entire sensor unit must be replaced when the battery is depleted. When the battery has died or the sensor was damaged, or there are no wheel sensors fitted at all, the TPMS will trigger an error code to be displayed on the dashboard.

Before purchasing, confirm that your vehicle's original sensor carries part number 407009322R (also printed as 40700-9322R on the sensor body). 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

This sensor operates at 433 MHz. Verify that your vehicle's TPMS system requires this frequency before purchasing, as some vehicles may use different frequencies depending on the market.

Important: This sensor features an auto-learning function that significantly simplifies installation:

• No coding is required after replacing the sensor

• Simply install the new sensor and after approximately 30 minutes of driving, the sensor will code itself to the vehicle

• You can replace as many sensors as you want—all four at the same time or just the ones that have malfunctioned

Additional installation notes:

• Scan tool may be required for some vehicle applications to gather sensor information—including the Sensor ID

• Control Unit/Software must be trained/updated for certain vehicle models

• 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 solid rubber valve stem. The sensor comes together with an attached mounting nut.

When installing the sensor, ensure the mounting nut is tightened to the specified torque of 4 Nm to prevent damage or improper sealing.

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 4–6 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

• Suitable for use in various climate conditions

When purchasing replacement sensors:

• Choose sensors that meet or exceed OEM specifications

• Verify the product includes a warranty (typically 12 months)

• Ensure the sensor is supplied new and in original packaging

• Confirm the sensor includes the appropriate valve stem configuration and mounting nut

After installation:

• Drive the vehicle for approximately 30 minutes to allow the sensor to auto-learn

• 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

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

• Make and model

• Year and month of production

• Target market (as frequencies may differ by region)
