【NGK OZA601-EJ4-92911 Oxygen Sensor 92911 Total Length 490mm 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 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". Based on the signal from the O2 sensor, the ECU performs control near the stoichiometric air-fuel ratio, where harmful substances in the exhaust gas are most effectively purified, by making the fuel leaner when it is rich compared to the stoichiometric air-fuel ratio, and richer when it is lean. In this way, 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.
Wideband 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 enables engine control outside of the stoichiometric air-fuel ratio (λ=1), such as lean-burn control. There are also early activation type wideband air-fuel ratio sensors that maintain the characteristics of conventional wideband air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (starts operation within 5 seconds after engine key ON) through an integrated element and heater structure.
【Need for Replacement】
O2 sensors are constantly exposed to exhaust gas 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 new car*
*Varies depending on vehicle usage conditions.
Overall length: 490mm
The overall length is the length from the gasket to the tip of the connector.
Compatible manufacturer: Suzuki

■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 understand.

■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) Inspect and replace 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) If dropped or subjected to impact, the internal ceramic element may break, so please be careful.
(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 the 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, screw it in with your fingertips, then use a wrench to tighten it to the following tightening torque as a guide.
【Part numbers starting with "LZA", "OZA", "OZR", "UAR"】:
Sensors with thread diameter 18mm, pitch 1.5mm, Hex22mm = 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,
always clear (reset) the diagnostic (self-diagnosis/OBD) error code according to the service manual, etc.
Failure to clear the error code may lead to problems such as the MIL not turning off.
