Oxygen Sensor 5149180AA / 56028994AB for Jeep, Ram, Dodge, Chrysler & Fiat
These Lambda Sensors are Original Equipment (OE) components manufactured for the Mopar group, including Chrysler, Dodge, Jeep, Ram, Fiat, and SRT vehicles. The OE numbers 5149180AA and 56028994AB are both widely used across the same vehicle platforms and are frequently cross-referenced together in parts catalogues.
These sensors monitor oxygen content in the exhaust gases and relay this information back to the Engine Control Unit (ECU) to ensure the optimal air-fuel mixture is maintained throughout operation for efficient combustion and reduced emissions.
Important Note: These are two different sensors with different specifications and applications. 5149180AA is a 4-wire heated sensor used in both upstream and downstream positions depending on the vehicle, while 56028994AB is a 4-wire heated regulating sensor typically installed in the before-catalyst (upstream) position. Always verify your original sensor's part number, connector shape, cable length, and position before ordering.
