Introduction:

Welcome to AutoMan Spare Parts, your No.1 source for OEM nitrogen oxide (NOx) sensors in Canada. We specialize in providing premium-quality automotive emission control parts at unbeatable prices.
One of our top-selling products is the 5WK97103 Hino Truck NOx Sensor with Control Module (A2C93843000-01 / SNS503 OEM) — engineered for precision, performance, and long-term reliability in heavy-duty Hino diesel trucks.

What is a NOx Sensor and Why It Matters for Hino Trucks?

A NOx sensor (Nitrogen Oxide Sensor) is a vital component in your truck’s exhaust after-treatment system, responsible for measuring the amount of nitrogen oxide emitted from the engine. The data helps the ECU (Engine Control Unit) adjust the air-fuel ratio and urea (DEF) injection to reduce harmful emissions and maintain compliance with environmental regulations.

For Hino trucks, the 5WK97103 / A2C93843000-01 / SNS503 OEM NOx sensor ensures:

• Optimal SCR (Selective Catalytic Reduction) performance

• Improved fuel efficiency

• Reduced engine derating

• Extended DPF lifespan

• Compliance with Euro IV, V, and VI emission standards
