Details

Fits Mazda CX-9 2016-2023. Part number PY8V188G1.

Replace the front oxygen sensor when the check-engine light appears, fuel consumption rises, or the engine idles roughly, since it regulates the air-fuel mixture and keeps combustion efficient.

  • Replacement sign: Check-engine light with higher fuel use and unstable idle.
  • Approximate lifespan: Typically lasts about 100,000 to 150,000 km depending on driving conditions.
  • Install requirement: Installation needs a dedicated oxygen-sensor socket and is best done on a cold engine by a qualified technician.
