It is more accurate than the traditional O2 sensors. In gasoline engines, wideband sensors help the engine control unit achieve optimal combustion for fuel efficiency and reduce emissions. In diesel engines, these sensors ensure the diesel and air mixture is correct for efficient combustion. By monitoring the air-fuel ratio. It also allows for lambda control. This function adjusts the combustion parameters to match the desired target value, regardless of the fuel quality or engine state. The WBO2S has four or five pins, depending on the vehicle's needs. Two of the pins are for the heater, while one is for the signal ground, and the rest are for the signal and reference voltage.
• Air-fuel ratio sensor: An air-fuel ratio sensor measures the levels of oxygen in the exhaust. It is similar to the wideband oxygen sensor but provides a more precise measurement of the air-fuel ratio. The higher precision makes it more suitable for modern vehicles with strict emission regulations and precise control of the combustion process. The accurate air-fuel ratio is also vital for fuel-efficient vehicles. By making sure that the combustion mixture is optimal, the air-fuel ratio is controlled, which improves vehicle performance and reduces emissions.
• NTK oxygen sensor: NTK is a brand under the spark plug manufacturer NGK. NTK specializes in ignition components of vehicles, including O2 sensors. NTK oxygen sensors are known for their precision and high quality. They are made using high-quality materials and advanced technologies to make sure they last and give reliable readings. NTK offers a wide range of oxygen sensors that fit different vehicles, including those with complex engine control units.
• NTK 4 pin oxygen sensor: The 4-pin NTK oxygen sensor has four wires. Two of the wires are for the heater, while the other two are for the signal and signal ground. The heater wires supply current to the built-in heater, warming the sensor to the desired temperature. The signal wire carries the sensor's readings to the engine control unit, while the signal ground wire provides a reference point for the sensor's output.
• NTK 5 pin oxygen sensor: The 5-pin NTK oxygen sensor has an extra pin compared to the 4-pin sensor. There is a reference voltage pin in the 5-pin sensor. This pin supplies a reference voltage to the sensor from the engine control unit. The other four pins are the same as those in the 4-pin sensor. The extra pin allows for more precise measurements and better communication between the sensor and the engine control unit. Not all vehicles need an oxygen sensor with five pins, so it is important to double-check the vehicle's requirements before buying one.
