Multifunction Sensor Citroën Peugeot 1489150080 6445QX

Description

Multifunction Sensor For Citroën C8 And Peugeot 807

This multifunction sensor is designed for the HVAC system of Citroën C8 and Peugeot 807 vehicles. Supplied with reference codes 1489150080 and 6445QX, it is commonly used as an interior temperature / climate sensor to provide accurate cabin readings to the automatic climate control unit. It is a direct-fit replacement part for mechanics and DIY enthusiasts who need reliable climate regulation and easy identification by product number.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C8, Peugeot 807
• Product Codes: 6445QX, 1489150080
• Other Numbers: NFP

Function

The sensor supplies the vehicle’s climate control with cabin temperature data and other environmental inputs required for automatic HVAC regulation. Accurate readings allow the climate system to control blower speed, blend doors and compressor operation to maintain the selected interior temperature. When the sensor provides faulty or intermittent signals, occupants may experience incorrect temperature, constant compressor cycling or reduced comfort.

Fitment And Compatibility

Intended for Citroën C8 and Peugeot 807 models (typical production years 2002–2014). Compatibility is commonly checked by the product codes 1489150080 and 6445QX — these numbers are frequently used by technicians when searching for the correct replacement.

Replacement Procedure

1. Park the vehicle on a level surface, switch off ignition and disconnect the negative battery terminal to avoid short circuits.
2. Remove the necessary trim pieces to access the dash / HVAC housing area where the sensor is located. Location varies by model — usually behind the glovebox, center console or within the HVAC housing.
3. Unplug the electrical connector from the sensor. Inspect the connector for corrosion or damaged pins.
4. Remove the sensor from its mounting (clips or screws), fit the new sensor in the correct orientation and secure it.
5. Reconnect the electrical connector, reassemble trim, reconnect the battery and perform a basic system check: verify that the climate control responds and that cabin temperature readings are sensible.

Mounting Recommendations

• Always disconnect the negative battery terminal before starting work.
• Handle the sensing element carefully; avoid touching the sensor opening or exposed components.
• Ensure connectors are clean and free of corrosion. Use dielectric grease sparingly on connectors if long-term protection is needed.
• Secure wiring to prevent chafing and ensure the sensor is mounted in the correct orientation for accurate readings.
• After installation, allow the climate control a few minutes to stabilize; in some cases, a vehicle electrical reset (battery disconnect) will clear stored faults.

Most Common Failure Reasons

Failures are most often caused by moisture ingress, dust accumulation, connector corrosion, thermal stress from long service life, or accidental damage during dashboard work. On older vehicles (typically 10+ years), sensors can degrade and produce inaccurate readings leading to poor climate control performance. Replacing a faulty sensor usually restores correct automatic HVAC behavior.

Choose this direct-fit multifunction sensor when you need a reliable replacement identified by part numbers 1489150080 or 6445QX — suitable for professional workshops and competent DIYers working on Citroën C8 and Peugeot 807 HVAC systems.
