NPS DOX-0430 Lambda Probe Denso

NPS DOX-0430 Lambda Probe Denso is a high‑performance exhaust oxygen sensor designed to deliver precise air‑fuel mixture control for a wide range of Jaguar and Ford vehicles. The probe’s advanced ceramic sensing element measures the oxygen content in exhaust gases, enabling the engine management system to adjust fuel injection and maintain optimal combustion efficiency.

Key Features

High Accuracy & Fast Response: The sensor incorporates a ceramic zirconia element that reacts quickly to changes in exhaust composition. This rapid response ensures the engine controller receives real‑time data, allowing for immediate adjustments and reducing emissions.

Robust Construction: Encased in a durable stainless steel housing, the probe withstands high temperatures and harsh chemical environments typical of automotive exhaust systems. The sealed connector protects against moisture and vibration, extending service life.

Wide Compatibility: Engineered to fit both left‑hand and right‑hand positions, the DOX-0430 is suitable for a variety of models including Jaguar X‑Type, XJ, XK 8, and Ford Jaguar variants. Its 4‑wire configuration (signal, ground, heater, and power) supports heated operation for rapid warm‑up in cold climates.

Low Power Consumption: The sensor’s design minimizes electrical draw, preserving battery life while delivering reliable performance under all operating conditions.
