Pollak 66-002 2010-2014 GM Downstream Diesel Nitrogen Oxide (NOx) Sensor

Keep Your Fleet Compliant and On the Road
The Pollak 66-002 Diesel NOx Sensor is a high-precision replacement component designed to keep your diesel exhaust system operating within legal emission limits. By accurately measuring nitrogen oxide levels in the exhaust stream, this sensor provides the critical data your Engine Control Unit (ECU) needs to manage the Selective Catalytic Reduction (SCR) system. A failing sensor can lead to poor engine performance, increased fuel consumption, and costly vehicle derate (limp mode) conditions.

Engineered for Harsh Exhaust Environments
Exhaust sensors face extreme heat, heavy vibration, and soot accumulation. The Pollak 66-002 is built to endure these conditions, featuring a robust ceramic sensing element and a corrosion-resistant housing. It offers an OEM-quality fit and function at a competitive price point, making it the ideal choice for maintenance and repair on modern diesel trucks.

Precision Performance and Efficiency
An accurate NOx sensor doesn't just keep you compliant—it saves you money. By optimizing the dosing of Diesel Exhaust Fluid (DEF), the 66-002 helps prevent excessive fluid consumption and reduces the strain on your Diesel Particulate Filter (DPF). This direct-fit sensor ensures a straightforward installation, restoring your truck’s efficiency and power.

Key Features:

• Real-Time Accuracy: Precision monitoring of NOx levels to maintain optimal SCR efficiency.

• Extreme Durability: Designed to withstand high exhaust temperatures and chemical exposure.

• Prevents Limp Mode: Helps avoid engine derate conditions caused by faulty emissions data.

• Direct Fit: Engineered for a seamless "plug and play" replacement in compatible diesel systems.

• Cost-Effective Reliability: High-quality alternative to expensive dealership-branded sensors.

• Warranty: Protected by a 1-year limited warranty.
