道奇吉普氧传感器 234-5150 68195741AA 68087364AA 原装替换

If your Dodge or Jeep shows check engine light, increased fuel consumption, rough idle, or weak acceleration, it is likely the oxygen sensor aging or failure. This part monitors oxygen content in exhaust and feeds signals to the ECU to precisely control the air-fuel ratio for efficient combustion and emissions compliance. OEM replacement part; fits many Dodge and Jeep models. OEM number 68087364AA (also compatible with 68195741AA, 234-5150). Installation requires cooling the engine and using a dedicated socket to remove the old part carefully to avoid damaging threads or wiring; apply a little anti-seize to prevent high-temperature sticking.
