For Mitsubishi Pajero V73, V93 and other models with 6G72 or 6G74 engines, OEM replacement oxygen sensor options include MR578114 and 234000-8684. The housing is corrosion-resistant stainless steel, with a high-temperature ceramic sensing element inside, capable of withstanding long-term exhaust system heat loads. This sensor provides real-time air-fuel ratio feedback to the ECU to ensure combustion efficiency, prevent high fuel consumption and emissions violations. Installed on the exhaust pipe, disassembly of related piping is required; professional technicians are advised to ensure sealing.
