■Product Description
NTK O2 Sensor Detects Ideal Air-Fuel Ratio
Sophisticated control is required to reduce harmful substances (HC, CO, NOx) in exhaust gases. O2 sensors play an important 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 receives a signal from the O2 sensor indicating that the fuel is rich relative to the stoichiometric air-fuel ratio, it leans the fuel mixture. If the fuel is lean, it enriches the fuel mixture. This allows control near the stoichiometric air-fuel ratio, which most effectively purifies harmful substances in the exhaust gas. Thus, NTK O2 sensors are crucial components in 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. It also enables engine control outside the stoichiometric air-fuel ratio (λ=1), such as lean-burn control. In addition, there are 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 (start operating within 5 seconds after the engine key is turned ON) through a integrated structure of the element and heater.
【Necessity of Replacement】
O2 sensors are constantly exposed to exhaust gases exceeding 600°C and accumulate combustion byproducts, operating in very harsh environments.
Using a degraded or damaged O2 sensor can lead to various problems.
5 years or 80,000 km or more from new car*

■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 an O2 sensor with the correct part number as specified in this manual.
(4) It may not function properly if used in modified vehicles.
(5) Be careful not to drop or shock the sensor, as this may break the internal ceramic element.
(6) Anti-seize compound is 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 body.
➉ Do not use an impact wrench when installing the sensor.
(11) When installing the sensor, screw it in by hand, then use a wrench to tighten it to the following approximate torque:
【Part numbers starting with "LZA", "OZA", "OZR", "UAR"】:
Sensors with thread diameter 18mm, pitch 1.5mm, Hex 22mm = approximately 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 hot parts.
(13) Route the lead wire 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
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.
