■Product Description
NTK O2 Sensor detects the ideal air-fuel ratio
Advanced control is required to reduce harmful substances (HC, CO, NOx) in exhaust gases. O2 sensors play a crucial role in detecting the oxygen concentration in exhaust gases and feeding this information back to the ECU*1.
NTK O2 sensors detect the oxygen concentration in the exhaust gas and feed 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 determines that the fuel is too rich based on the signal from the O2 sensor, it leans the mixture. If the fuel is too lean, it enriches the mixture, thereby controlling the engine near the stoichiometric air-fuel ratio, where harmful substances in the exhaust gas are most effectively purified. Thus, NTK O2 sensors are essential components for reducing harmful substances in exhaust gases.

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. Therefore, more precise engine control is possible than with zirconia O2 sensors. Additionally, engine control at air-fuel ratios other than the stoichiometric ratio (λ=1), such as lean-burn control, becomes possible. There are also early-activating 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 (start operating within 5 seconds after the engine key is turned ON) through an integrated element and heater structure.
【Necessity of 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.

■Precautions
O2 sensors are designed specifically 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 O2 sensor part number listed in this document.
(4) It may not function correctly if used in modified vehicles.
(5) Dropping or impacting the sensor may cause the internal ceramic element to break, so please be careful.
(6) Anti-seize compound has been applied to the threaded part of the sensor. To prevent adhesion of dirt, etc.,
remove the protective cap immediately before installing the sensor.
(7) Do not wipe off the anti-seize compound.
(8) If anti-seize compound gets on your hands, etc., wash it off immediately with water.
➈ Do not twist or bend the lead wire fixed to the main unit.
➉ Do not use an impact wrench when installing the sensor.
(11) When installing the sensor, thread it in with your fingertips, then use a wrench to tighten it to the following approximate torque:
【Part numbers starting with "LZA," "OZA," "OZR," "UAR"】:
Sensor with screw diameter 18mm, pitch 1.5mm, Hex 22mm = approx. 45-55 N・m (4.5-5.5 kgf・m)
(12) Do not allow the lead wires or connector 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 only the O2 sensor 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.
