Electrical system
This is a genuine interior temperature sensor assembly (OE:3681120-C6100) for Dongfeng GX&KX, critical for calibrating the cab HVAC system. It fits all GX&KX models, featuring ±0.5℃ measurement accuracy (12V-compatible, Dongfeng-certified). Fleet tests show it reduces HVAC energy consumption by 20% by maintaining stable cab temperatures, improving driver comfort during long hauls. The plug-and-play design aligns with factory electrical harnesses, enabling 5-minute installation for technicians.

PRODUCT DESCRIPTION
Genuine Factory Build & High-Precision Calibration
This interior temperature sensor (OE:3681120-C6100) adheres to Dongfeng’s genuine part standards, integrating a high-sensitivity thermistor (±0.5℃ accuracy) and IP44-rated housing (resistant to cab moisture/dust). It undergoes ISO 9001-certified temperature calibration to ensure consistent readings across -40℃ to 85℃—critical for the HVAC system to maintain optimal cab comfort. Unlike aftermarket sensors, it matches the original electrical protocol, avoiding HVAC system malfunctions.
Perfect Compatibility & Hassle-Free Fitment
It is fully compatible with Dongfeng GX (4x2 cargo, 6x4 tractor) and KX (6x4 heavy haul, 8x4 construction) models. To confirm fitment, cross-check your truck’s VIN or existing sensor OE number with 3681120-C6100. The sensor’s factory-molded design aligns exactly with the cab’s original mounting slot—no adjustments or modifications are needed, and it locks securely in place to avoid loose connections (a common issue with generic sensors).
Enhance HVAC Efficiency & Driver Comfort
As a key electrical system component, this sensor enables the HVAC system to adjust temperature dynamically—reducing energy consumption by 20% (per Dongfeng fleet data) and eliminating manual temperature tweaks. Its ±0.5℃ accuracy ensures stable cab temperatures (no overheating/cooling), lowering driver fatigue during long-haul trips. It also extends HVAC component lifespan by 15% via optimized operation.
