Replacement Part Number: 1536254 1.In the event of an oxygen sensor failure, the optimum fuel mixture cannot be maintained and the engine emits harmful carbon monoxide and excessive hydrocarbons, Oxygen Sensor Damage and emits black smoke. Therefore, it is important to troubleshoot or replace it in time. 2.Since the catalytic converter is responsible for eliminating harmful gases such as carbon monoxide and excess hydrocarbons from the vehicle's exhaust system, a faulty oxygen sensor can lead to premature catalytic converter damage. 3.A faulty oxygen sensor will increase the engine's fuel consumption and exhaust gas pollution. The engine will have unstable idle speed, increased fuel consumption, excessive oxygen consumption, lack of engine power, slow acceleration and black smoke. Therefore, it must be promptly troubleshoot or replace Product optimization and solution points 1.Oxygen sensors are designed to solve problems such as erratic idling, frequent stalling, and poor acceleration, thereby improving fuel economy and reducing carbon emissions, among other features 2.Oxygen sensors improve engine performance and fuel economy, reduce harmful emissions, and prevent premature catalytic converter damage and lean or rich engine operation, thus ensuring efficient engine operation to receive the correct air/fuel mixture Product installation location 1.Direct plug-in replacement oxygen sensors are easy to install in your vehicle and come with pre-coated threads to assist with installation 2.Oxygen sensor easy to install on your vehicle with pre-coated threads to assist with installation 3.Replacement of damaged sensors at the exhaust pipe, easy to install with pre-coated threads to assist with installation Product composition and material quality 1.O2 sensors are made of high quality metal materials with electronic components, high temperature resistant wire, with double protection layer, aluminum oxide trap layer, PTFE filter and stainless steel housing, durable, anti-oxidation, to ensure long-term stable performance 2.O2 sensors are made of high quality metal materials with electronic components and high temperature resistant materials for faster response time. Dual laser-welded stainless steel bodies can be fully submerged to seal in water for long life, oxidation and high temperature resistance to ensure long-term stable performance 1.Quality oxygen sensing accurately detects the oxygen content of exhaust gases, optimizing emissions and fuel economy and preventing the emission of harmful amounts of carbon monoxide and excessive hydrocarbons 2.Oxygen sensors ensure that the engine receives the correct air/fuel mixture, thus preventing the engine from running lean or rich, thus ensuring efficient engine operation, maintaining an optimal fuel mixture and eliminating harmful emissions from the vehicle exhaust system Quality confidence: 1.Oxygen sensors are manufactured to the highest standards of durability, oxidation resistance and high temperature resistance to ensure consistent long-term performance and to prevent lean or rich engine operation, thus ensuring that the engine runs efficiently and receives the correct air/fuel mixture 2.Manufactured to the highest standards of durability, oxidation resistance and high temperature resistance to ensure long term performance and fully tested to ensure 100% accurate data transfer to the engine management system for optimum engine operation and life 1.12 months warranty.
