丰田皇冠氧传感器 89467-30030 / 30040 / 35110 多编号通用

If your Toyota Crown experiences idle instability, rising fuel consumption, exhaust odor, or engine check light frequently on, this typically indicates oxygen sensor aging or failure. This part monitors exhaust oxygen concentration and sends signals to the ECU to precisely control air-fuel ratio for optimal combustion and emissions. This product is compatible with OEM numbers 89467-30030, 30040, 35110; fits multiple generations of Toyota Crown. Install with clean threads; tighten to specified torque to avoid ceramic damage; also check wiring connectors for oxidation and signal stability.
