Description
Product Overview
High-quality Outdoor Temperature Sensor designed for PSA group vehicles, sold under part number 6445F9. This direct-fit replacement restores accurate outside air temperature readings used by the vehicle’s climate control and driver information systems. The unit is commonly sought by its product number 6445F9, making correct identification fast for mechanics and DIY enthusiasts.
Key Benefits
- Direct-fit replacement for multiple Citroën and Peugeot models, reducing installation time.
- Improves accuracy of the outside temperature display and climate control logic.
- Compact, durable design manufactured to withstand typical under-bumper and exterior mounting environments.
Function and Symptoms of Failure
The outdoor temperature sensor measures ambient air temperature and feeds that signal to the vehicle’s climate control module and instrument cluster. When the sensor fails or gives incorrect readings, common symptoms include inaccurate outside temperature display, unpredictable HVAC behavior (incorrect automatic climate adjustments), and occasional fault codes related to the climate system.
Typical Causes Of Faults
- Water ingress or corrosion on connector pins caused by prolonged exposure to the elements.
- Physical damage from impacts or road debris.
- Wiring harness wear, connector corrosion or intermittent electrical connections.
- Internal sensor element failure due to age or thermal cycling.
Replacement And Installation Notes
Replacement is straightforward for a competent technician or an experienced DIYer. The sensor is typically mounted in the front bumper grille, behind the badge, or in/near the exterior mirror depending on the model. Typical steps:
- Switch off ignition and ensure a safe working environment; consult the vehicle manual for specific safety steps.
- Access the sensor by removing the relevant trim or grille panel.
- Disconnect the electrical connector, unclip or unscrew the sensor from its bracket and fit the new unit.
- Reconnect the connector, reassemble trims and verify the outside temperature reading on the dash. If fault codes are present, clear them with a diagnostic tool and confirm correct operation.
