Description

Maxfavor dedicated to provide the good selection, the latest cutting edge technology, and the good overall shopping experience. Maxfavor oxygen sensor is designed to detect the amount of oxygen in the exhaust stream. It is constructed from quality stainless steel, porous polytetrafluoroethylene, fluorine rubber, aluminum oxide, high-grade platinum and ceramics. Maxfavor oxygen sensor features double protection layer, aluminum oxide trap layer, porous PTFE filter and stainless steel housing. It is manufactured with precision to meet OE standards and can be installed easily and ensures longevity. When the engine temperature reaches normal, unplug the wire connector of the oxygen sensor and use a resistance meter to detect the resistance between the oxygen sensor terminals. The resistance value should meet the requirements of the specific model standard value (generally 440Ω) Use the fault diagnosis instrument to detect the engine, extract the fault code, and observe the data stream. The operation of the oxygen sensor is judged by the magnitude and frequency of the voltage change of the oxygen sensor. If it is working properly, the voltage should be between 0.4 and 0.6V. If the voltage is always at 0.45V, the oxygen sensor will not work. Oil pollution: the surface of the probe is covered with a white or gray-black oily deposit on one side. Silicon poisoning: probe deposit color between bright white and granular light gray Lead poisoning: shiny rust layer on the probe surface Antifreeze contamination: a layer of dirt on the surface of the probe To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
