■Product Description
NTK O2 Sensor Detects Ideal Air-Fuel Ratio
Advanced control is required to reduce harmful substances (HC, CO, NOx) in exhaust gas. The O2 sensor plays an important role in detecting the oxygen concentration in exhaust gas and feeding it 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 ECU receives a signal from the O2 sensor indicating that the fuel is rich relative to the stoichiometric air-fuel ratio, it thins the fuel. If it is lean, it enriches the fuel, thereby controlling the engine near the stoichiometric air-fuel ratio where harmful substances in the exhaust gas are most effectively purified. Thus, the NTK O2 sensor is an important component in reducing harmful substances in the exhaust gas.

Specifications
【Features/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. This is a feature of zirconia-type sensors.
Wide-band air-fuel ratio sensors can detect how rich or lean the air-fuel ratio is relative to the stoichiometric air-fuel ratio. Therefore, more precise engine control is possible than with zirconia O2 sensors. It also allows for engine control outside of the stoichiometric air-fuel ratio (λ=1), such as lean-burn control. There are also early activation wide-band air-fuel ratio sensors that maintain the characteristics of conventional wide-band air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (start operation within 5 seconds after the engine key is turned ON) due to the integrated structure of the element and heater.
【Need for Replacement】
O2 sensors are constantly exposed to exhaust gas 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.
5 years or 80,000 km or more from new car purchase*
*May vary depending on vehicle usage conditions.

■Precautions
O2 sensors are designed specifically for each vehicle model and engine, so they are not interchangeable with other types.
(1) Always stop the engine before inspecting, replacing, or adjusting.
(2) Perform inspection and replacement according to the service manual of each automobile manufacturer.
(3) Use the correct O2 sensor part number listed in this document.
(4) It may not function properly if used in modified vehicles, etc.
(5) Please be careful as dropping or impacting the sensor may cause the internal ceramic element to break.
(6) Anti-seize compound is applied to the threaded part of the sensor. To prevent dirt from adhering,
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, screw it in with your fingertips, then use a wrench to tighten it to the following approximate tightening torque.
【Part numbers starting with "LZA", "OZA", "OZR", "UAR"】:
Sensors with thread diameter 18mm, pitch 1.5mm, Hex 22mm = approx. 45-55 N・m (4.5-5.5 kgf・m)
(12) Do not allow the lead wire or connector to touch the exhaust manifold or other high-temperature parts.
(13) Route the lead wire as originally intended 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 be sure to clear (reset) the diagnostic (self-diagnosis/OBD) error codes.
Failure to clear the error codes may lead to problems such as the MIL not turning off.
