Product Overview

The Interior Air Temperature Sensor 6445ZT is a direct-fit electrical component designed to provide accurate cabin temperature readings to the vehicle climate control system. Commonly referenced by part number 6445ZT, this sensor helps the HVAC module manage heating, ventilation and air conditioning for stable cabin comfort and efficient climate regulation.

Key Features & Benefits

• Accurate Cabin Readings: Provides the climate control with the temperature input required for reliable automatic climate regulation.
• Direct Fit: Designed for easy replacement in compatible Citroën and Peugeot models.
• Improved Comfort And Efficiency: Helps reduce oscillation of blower speed and unnecessary compressor cycling by giving precise temperature feedback.
• Part Number Search Friendly: Frequently searched by product code 6445ZT for fast identification.

Technical Information

• Additional Numbers: 6445.ZT

Technical Details

Interior temperature sensors of this type typically use an NTC (Negative Temperature Coefficient) thermistor element to convert air temperature into a voltage or resistance signal for the climate control unit. The sensor is located in the HVAC intake area or dashboard ducting to measure cabin air rather than exterior temperature. Electrical connector and pinout vary by model — ensure proper alignment of the mating connector during installation.

Installation Recommendations

• Preparation: Park the vehicle on a level surface, switch ignition off and remove the key.
• Safety: Disconnect the negative battery terminal before starting work to avoid electrical damage or fault codes when handling HVAC components and connectors.
• Access: The sensor is usually mounted in the HVAC housing or air recirculation duct behind the dashboard or glovebox. Remove trim panels as required to reach the sensor location.
• Removal: Unplug the electrical connector, release the retaining clip or screws and extract the sensor carefully to avoid damage to the duct or housing.
• Installation: Fit the new sensor into the original seat, secure clips or screws, reconnect the electrical connector and reassemble interior trim. Reconnect the battery and run the vehicle to verify proper HVAC operation.
• Recommendation: Use proper trim tools to avoid damaging interior panels. If fault codes remain after replacement, perform a diagnostic scan to clear residual faults and verify sensor signal under live data.

Why This Part Fails

• Contamination And Moisture: Dust, humidity or water ingress can alter sensor readings or corrode the connector.
• Connector Corrosion Or Wiring Damage: Poor contacts or broken wires cause intermittent or no signal to the climate control module.
• Thermistor Drift Or Failure: Ageing of the sensing element can lead to inaccurate readings and poor climate control performance.
• Physical Impact Or Improper Handling: Forceful removal or impact during dashboard work can damage the sensor housing or element.
• No Scheduled Replacement Interval: The sensor is replaced when faulty symptoms appear, such as incorrect cabin temperature reporting, erratic blower behaviour or constant HVAC cycling.

Compatibility And Fitment

Common Applications: Citroën C2, Citroën C3, Peugeot 207, Peugeot 208. Always verify part number 6445ZT against the vehicle’s parts listing to confirm fitment for the exact model and production range.

Final Notes

This sensor is a straightforward and cost-effective component to restore correct climate control function. Replacing a faulty interior temperature sensor often eliminates comfort complaints and reduces HVAC system wear caused by incorrect temperature regulation.
