    Oxygen Sensor

  • Description:

    GM part 12640453 is a genuine GM Heated Oxygen Sensor (HO2S), commonly listed as a pre-catalyst (upstream) oxygen sensor for GM 3.6L V6 applications.

    What it is

    • GM Part Number: 12640453
    • Description: Heated Oxygen Sensor (O₂ sensor)
    • Type: 4-wire, heated sensor
    • Location: Typically upstream (pre-catalyst), though some GM calibrations use it in multiple positions

    What it does This sensor measures oxygen content in the exhaust stream and sends data to the ECM so it can adjust:

    • Fuel mixture (air/fuel ratio)
    • Emissions control
    • Engine efficiency and fuel economy

    Common applications Based on GM catalog fitment, it is used on various vehicles with the 3.6L V6 (LFX/LGX family), including:

    • Chevrolet Camaro
    • Chevrolet Impala
    • Chevrolet Colorado
    • GMC Canyon
    • Cadillac XTS

    Fitment varies heavily by VIN and exhaust position, so the same part number may appear in multiple sensor locations depending on calibration.

    Key notes

    • Requires correct VIN verification for exact position (bank/sensor location)
    • Uses a heated element for faster closed-loop operation
    • Failure can trigger codes like P0130–P0167 depending on which sensor is affected

    If you want, I can map exactly which sensor position (Bank 1 Sensor 1 / etc.) it corresponds to on your specific vehicle if you share the VIN.


    GM Genuine OEM Heated Oxygen Sensor (MPN: 12640453) optimizes engine performance and emissions control by monitoring oxygen levels in exhaust gases across select GM vehicles. This authentic General Motors oxygen sensor is engineered to factory specifications and ensures proper fuel mixture regulation for enhanced efficiency.
