【NGK OZA603-EN5-95480 Oxygen Sensor 95480 Total Length 371mm O2】
■Product Description
NTK O2 Sensor detects ideal air-fuel ratio
Advanced control is necessary to reduce harmful substances (HC, CO, NOx) in exhaust gas. The O2 sensor plays a vital role in detecting the oxygen concentration in the exhaust gas and feeding this information back to the ECU*1.
The NTK O2 sensor detects the oxygen concentration in the exhaust gas and feeds it back to the ECU so that the fuel-air mixture ratio (air-fuel ratio) becomes the optimal stoichiometric air-fuel ratio "λ (lambda) = 1*2". If the fuel is too rich based on the O2 sensor's signal, the ECU thins out the fuel. If it's too lean, the ECU enriches the fuel, thereby controlling the mixture near the stoichiometric air-fuel ratio, where harmful substances in the exhaust gas are most effectively purified. Thus, the NTK O2 sensor is a crucial component in reducing harmful substances in exhaust gas.

Specifications
【Features and Structure】
Zirconia elements have the characteristic of generating electromotive force due to differences in oxygen concentration at temperatures exceeding 300°C. Utilizing this characteristic, zirconia-type sensors detect the difference in oxygen concentration between the inside and outside of the element (atmosphere and exhaust gas) and feed back to the ECU whether the fuel is rich or lean relative to the stoichiometric air-fuel ratio.
Wide-range air-fuel ratio sensors can detect how rich or lean the mixture is relative to the stoichiometric air-fuel ratio. This allows for more precise engine control than with zirconia O2 sensors. It also enables engine control at air-fuel ratios other than the stoichiometric air-fuel ratio (λ=1), such as for lean-burn control. There are also early activation wide-range air-fuel ratio sensors that maintain the characteristics of conventional wide-range air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (starts operating within 5 seconds after the engine key is turned ON) through an integrated structure of the element and heater.
【Need for Replacement】
O2 sensors are constantly exposed to exhaust gases exceeding 600°C and accumulate combustion products, operating in a very harsh environment.
Using a deteriorated or damaged O2 sensor can lead to various problems.

■Image Precautions
*Images are for illustration purposes only. Includes products with different sizes and colors. Product designs and specifications are subject to change without notice. Please be aware.

■Precautions
O2 sensors are specifically designed for each vehicle model and engine, so they are not interchangeable with other types.
(1) Always turn off the engine before inspection, replacement, or adjustment.
(2) Perform inspection and replacement according to the service manual of each automobile manufacturer.
(3) Use the correct part number O2 sensor listed in this document.
(4) It may not function correctly if used in modified vehicles.
(5) Be careful not to drop or subject the sensor to impact, as the internal ceramic element may break.
(6) Anti-seize compound is applied to the threaded part of the sensor. To prevent adhesion of dirt, etc.,
remove the protective cap just before installing the sensor.
(7) Do not wipe off the anti-seize compound.
(8) If anti-seize compound gets on your hands or other body parts, wash it off immediately with water.
➈ Do not twist or bend the lead wire fixed to the main body.
➉ Do not use an impact wrench when installing the sensor.
(11) When installing the sensor, hand-thread it, then use a wrench to tighten it to the following approximate torque:
【Part numbers starting with "LZA", "OZA", "OZR", "UAR"】:
Sensors with screw diameter 18mm, pitch 1.5mm, Hex 22mm = approximately 45-55 N・m (4.5-5.5 kgf・m)
(12) Do not allow the lead wires or connectors to come into contact with the exhaust manifold or other hot parts.
(13) Route the lead wires in the same way as the original and securely attach the connector.
(14) Depending on the condition of your vehicle, replacing the O2 sensor alone may not resolve the problem.
(15) When the MIL illuminates, before (or after) replacing the sensor, follow the service manual, etc., and
always clear (reset) the error code from the diagnostic (self-diagnosis/OBD) system.
Failure to clear the error code may lead to problems such as the MIL not turning off.
