Description
Premium replacement outdoor temperature sensor designed for PSA Group vehicles. The sensor measures outside ambient air temperature and supplies this data to the climate control system and instrument cluster. Accurate ambient readings help the HVAC system regulate cabin temperature correctly and provide reliable temperature readouts on the dashboard. Often searched and fitted by part number 6445F9.
Key Benefits
- Direct fit for multiple Citroën and Peugeot models
- Improves HVAC regulation and dashboard temperature accuracy
- Easy electrical connection for quick workshop or DIY replacement
Common Applications
Compatible with a range of PSA vehicles including Citroën C2, C3, C4, C5, C6, C8, Berlingo, Xsara and Peugeot 206, 207, 307, 407, 807, Partner, among others. Always verify fitment using the vehicle VIN or the part number 6445F9 before ordering.
Typical Failure Modes and Causes
Outside temperature sensors commonly fail due to moisture ingress, corrosion of the electrical contacts, wiring damage, or impact from road debris. Symptoms of failure include incorrect or erratic ambient temperature readings on the dashboard, improper HVAC behaviour, or temperature-related fault codes. Failure does not typically affect engine operation but can impair climate control performance.
Replacement Guide
Replacement is straightforward for experienced mechanics and competent DIYers. Typical steps:
- Locate the sensor (usually mounted at the front of the vehicle behind the grille or bumper area; exact location varies by model).
- Disconnect the battery as a precaution if required by workshop practice.
- Unplug the electrical connector and remove retaining clip or fastener.
- Install the new sensor, secure the fastener, and reconnect the connector.
- Verify operation by checking ambient temperature display and HVAC responses; clear any related fault codes if present.
