■Product Description
NTK O2 Sensor Detects Ideal Air-Fuel Ratio
Advanced control is required to reduce harmful substances (HC, CO, NOx) in exhaust gases, and the O2 sensor plays 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) is at the optimal stoichiometric air-fuel ratio of "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 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. This is a characteristic of zirconia-type sensors.
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 allows for engine control other than the stoichiometric air-fuel ratio (λ=1), such as lean-burn control. In addition, there are early activation type 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) due to the integrated structure of the element and heater.
【Necessity of Replacement】
O2 sensors are constantly exposed to exhaust gases exceeding 600°C and are subject to the adhesion of combustion products, operating in a very harsh environment.
Using a deteriorated or damaged O2 sensor can lead to various problems.
More than 5 years or 80,000 km from a new car*
*May vary depending on vehicle usage.
Overall length: 275mm
The overall length is the length from the gasket to the tip of the connector.
Heat shields and other covers are included; please use them as is without removing any parts.
Compatible manufacturer: Toyota
Compatible genuine part number: 89465-80011

■Precautions
O2 sensors are designed specifically for each car model and engine and 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 an O2 sensor with the correct part number as described in this document.
(4) If used in modified vehicles, it may not function correctly.
(5) Dropping or impacting the sensor may cause the internal ceramic element to break, so please be careful.
(6) Anti-seize agent 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 agent.
(8) If the anti-seize agent gets on your hands or other parts of your body, wash it off immediately with water.
(9) Do not twist or bend the lead wire fixed to the main unit.
(10) 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 torque:
【Part numbers starting with "LZA", "OZA", "OZR", "UAR"】:
Sensor with thread diameter 18mm, pitch 1.5mm, Hex 22mm = approx. 45-55N・m (4.5-5.5kgf・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 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 diagnostic (self-diagnosis/OBD) error codes.
Failure to clear the error codes may lead to problems such as the MIL not turning off.
