• Description:

  What it is

  GM part 12606671 is another oxygen sensor (O2 sensor)—very similar category to the one you asked about earlier.

  Example OEM part

  ACDelco / GM 12606671 Oxygen Sensor

  Details

  • Part #: 12606671
  • Type: Heated oxygen sensor
  • Other names:
    • Front O2 sensor
    • Upstream oxygen sensor
  • Function: Measures oxygen in exhaust gases to help the engine computer adjust fuel mixture

  Where it’s used

  • Typically installed before the catalytic converter (upstream position)
  • Common on GM 2.4L 4-cylinder engines
  • Found in vehicles like:
    • Chevy Equinox
    • GMC Terrain
    • Chevy Malibu
    • Chevy HHR

  What it does (quick)

  • Monitors exhaust oxygen levels
  • Sends signal to ECU
  • Helps control:
    • Fuel economy
    • Emissions
    • Engine performance

  Quick takeaway

  • 12559850 = O2 sensor
  • 12606671 = also O2 sensor (newer/different application)
  • 12591093 = internal engine bearings

  👉 So this one is not internal engine—it’s part of the emissions/exhaust system.

  If you want, give me your year/make/model/engine and I’ll tell you:

  • exact location (Bank 1 Sensor 1 vs Sensor 2)
  • torque spec
  • best aftermarket equivalent vs OEM 👍
