丰田埃尔法氧传感器 89467-58030 / 89465-42170 精准匹配

Toyota Alphard oxygen sensor (OEM numbers 89467-58030/89465-42170) precisely matches factory mounting position, installed on the exhaust manifold or exhaust pipe, continuously monitors exhaust oxygen content and transmits signals to the ECU to optimize the air-fuel ratio, ensuring efficient engine combustion. Installation difficulty is moderate; typical labor time about 1 hour; protect threads from damage during installation. If fuel consumption rises abnormally, acceleration is weak, or the engine warning light is on, and the tailpipe smells acrid, sensor performance has degraded and replacement is advised to ensure emissions compliance and smooth driving.
