Description
Multifunction Sensor for Citroën C8 and Peugeot 807
Product Overview
This multifunction sensor is designed for Citroën C8 and Peugeot 807 vehicles and is commonly used inside the HVAC/climate control system to provide accurate cabin environment data. The unit improves automatic climate regulation, supporting comfortable interior temperature control and reliable operation of the air conditioning system. Ideal for professional mechanics and experienced DIYers who service Stellantis vehicles.
Key Features And Benefits
- Direct-fit replacement for original equipment on applicable Citroën and Peugeot models.
- Improves responsiveness and stability of automatic climate control.
- Often searched and identified by part numbers 1489150080 and 6445QX—useful for quick lookup.
- Compact design for simple integration into existing sensor mounts and wiring harnesses.
Applications
Designed for Citroën C8 and Peugeot 807 models (commonly fitted on model years 2002–2014). Typically installed in the dashboard or inlets related to the HVAC system to measure cabin conditions used by the vehicle’s climate logic.
Installation
Replacement is straightforward for a trained technician or competent DIYer with basic tools. Typical steps:
- Disconnect the vehicle battery before starting work to avoid short circuits and control module issues.
- Remove the relevant dashboard trim or ventilation grille to access the sensor location (location varies by model and trim).
- Unplug the electrical connector and remove the sensor from its mounting (clip or screw, depending on version).
- Install the new sensor, secure the mounting, reconnect the harness and reassemble the trim.
- Reconnect the battery and verify proper operation of the climate control (automatic mode) and that there are no error codes related to the sensor circuit.
Installation Recommendations
- Use appropriate trim tools to avoid damage to dashboards and clips.
- Check connector terminals for corrosion before fitting; clean if necessary to ensure solid electrical contact.
- After installation, run the climate system through automatic cycles to confirm stable temperature regulation.
Why The Part Fails
Failures are typically caused by long-term exposure to moisture, contamination or dirt ingress, connector corrosion, thermal stress, or internal electronic component degradation. Mechanical damage during previous servicing or impact to the dash area can also affect sensor function. Symptoms of failure include incorrect cabin temperature readings, poor automatic climate control performance, or related HVAC fault codes.
