Description
Interior Air Temperature Sensor for Citroën and Peugeot vehicles.
The Interior Air Temperature Sensor (part number 6436G4) is a direct-fit replacement component designed for Citroën and Peugeot HVAC systems. It measures cabin air temperature and provides the climate control unit with the signal required to regulate heating, ventilation and air conditioning precisely. This sensor is commonly searched by its part code 6436G4 and is suitable for both professional workshops and experienced DIY mechanics who service Stellantis group vehicles.
Key Benefits
- Accurate cabin temperature feedback for stable climate control operation
- Direct replacement for OE-specified units with the 6436G4 code
- Simple, time-saving installation for mechanics and home repairers
- Helps restore proper HVAC regulation and passenger comfort
Compatibility / Typical Applications
Fits various Citroën and Peugeot models. Common applications include:
- Citroën C4
- Peugeot 3008 I
- Peugeot 307
- Peugeot 5008 I
How The Sensor Is Replaced
The interior air temperature sensor is typically mounted in the HVAC housing, near the air intake or evaporator area, or behind trim panels such as the glovebox or center console depending on the model. Typical replacement steps:
- Access the sensor location by removing the necessary trim panels or glovebox according to the vehicle model.
- Disconnect the electrical connector from the sensor.
- Release any retaining clips or remove the small screws holding the sensor in place and pull the sensor from its housing.
- Install the new sensor, secure clips or screws, and reconnect the electrical connector.
- Reassemble trim and verify proper operation of the climate control system (set different temperatures and observe response).
Installation Recommendations
- Always follow the vehicle manufacturer’s disassembly sequence to avoid damage to trim and fasteners.
- Disconnect the battery before beginning work to prevent short circuits and protect vehicle electronics.
- Inspect the sensor connector and wiring for corrosion or damage and clean or repair as necessary before installing the new sensor.
- After installation, confirm correct HVAC behavior and that the sensor wiring is properly routed and secured away from moving parts.
Why This Part Most Often Fails
Interior air temperature sensors commonly fail due to:
- Moisture ingress and condensation inside the sensor housing leading to corrosion or short circuits.
- Connector corrosion or poor electrical contact from age or exposure to humidity.
- Contamination from dust and debris in the HVAC system affecting the sensing element.
- Mechanical damage during previous repairs or from impact to surrounding trim.
