Description
Product Overview
The NAYAMOL JC3Z-5L239-C Diesel Exhaust Gas Sensor is engineered for the demanding environment of modern diesel engines. Constructed from high‑temperature‑resistant metals and advanced ceramics, the sensor endures the extreme heat and corrosive gases found in the exhaust system of 6.7L V8 Ford Super Duty trucks (2017‑2022). Its plug‑mount design integrates a robust electrical connector that delivers a clean, precise signal to the engine control unit, enabling accurate monitoring of particulate levels and supporting optimal combustion control. Key specifications include a compact package of 6.85 x 4.25 x 2.05 inches, a lightweight 8.3‑ounce construction, and a universal fit for OEM part numbers JC3Z‑5L239‑C, 0281006766, 0281007522, HC3Z5L239D, and HC345L23.
Usage
Designed for both everyday commuting and heavy‑duty hauling, this sensor excels in environments where exhaust temperatures regularly exceed 800°C. It is ideal for fleet operators, off‑road contractors, and owners of performance‑tuned trucks who require reliable emissions data to maintain compliance and engine health. Installation is straightforward: simply disconnect the old sensor, align the plug‑mount connector, and seat the new unit without tools. The sensor’s rapid response time ensures real‑time feedback during acceleration, towing, and prolonged idling, making it a versatile component for a wide range of driving conditions.
