Installation Recommendations
Replacement is suitable for experienced mechanics and competent DIYers. The interior temperature sensor is usually mounted in the HVAC housing or behind a dashboard ventilation grille—locations vary by model. Typical replacement steps:
- Park the vehicle on a level surface, switch off ignition and remove key.
- Disconnect the negative battery terminal before starting work to avoid electrical faults.
- Access the sensor by removing the relevant trim panel, glovebox or center console pieces depending on the model; take care with plastic clips and fasteners.
- Unplug the electrical connector and remove the sensor retaining clip or screws.
- Install the new sensor, secure fastening, reconnect the connector and reassemble trim in reverse order.
- After installation, check HVAC operation and verify that cabin temperature readings respond normally during heating and cooling cycles.
Recommended Tools: Trim removal tool set, Torx/Phillips drivers, multimeter for quick signal checks. Allow 30–90 minutes depending on vehicle and access.
Why The Part Most Often Fails
Interior temperature sensors typically fail or give incorrect readings for the following reasons:
- Contamination From Dust And Debris: Dust buildup inside the sensor or grille can insulate the sensing element and impair accuracy.
- Moisture Ingress Or Condensation: Water exposure leads to corrosion of contacts or damage to the sensing electronics.
- Connector Corrosion Or Wiring Damage: Faulty wiring, loose pins or corroded terminals cause intermittent signals or failure.
- Age And Thermal Drift: Over many years the sensing element can drift out of specification, causing incorrect temperature reports.
Notes For Buyers
Search By Part Number: Customers often find this sensor using references 9647527180 or 6445VC. Check vehicle model and year to confirm physical fitment before ordering. Designed primarily for Citroën and Peugeot passenger cars listed above.
Mounting And Coding – Important
– The unit is used and may be paired with the original vehicle (VIN/PIN/keys).
– Options To Commission:
1) Cloning data from the old unit (EEPROM/Flash) – after cloning the unit is plug and play.
2) Virginization and subsequent initialization/telecoding via DiagBox (or online) + key adaptation.
– Recommended to be performed by a technician with PSA service equipment (DiagBox/Lexia/PP2000).
– Always disconnect the battery before removal/installation and follow the manufacturer’s procedure to avoid damaging the unit.
