NTK is the world’s largest supplier and manufacturer of OEM oxygen sensors. Oxygen sensors play a critical role as part of the vehicle’s on-board diagnostic system in maintaining optimal engine performance, maximizing fuel efficiency and reducing harmful emissions. While conventional switching oxygen sensors only switch rich or lean, wideband oxygen (or Air-Fuel Ratio) sensors produce a linear output signal that allows the ECU determine exactly how rich or lean an engine is running and make continuous and precise adjustments of the air-fuel mixture to stay closest to stoichiometric, providing the best possible combustion and fewest emissions. A ceramics company at our core, NTK uses state-of-the art technology enabling complete control of the ceramics used in our wideband oxygen sensors from raw material to finished product. Trust The Sensor Specialist for full-line market support and OE application technology.

The Fuel Level Sensor is a much more critical sensor that just reporting the fuel level in the fuel tank for the purpose of the fuel level gauge reading. The engine operating system and the vehicles emissions control system requires this input to protect the engine should the fuel level be so low as to create a lean operating condition and possibly damage the engine. The other feature, and just as important, is the evaporative emissions system operation. Fuel level must typically be between 15%-85% for the system to purge the fuel vapors.
