    About the “OR” mark​

    The “OR” you circled likely stands for “Out of Range” or “Over Range.”
    It means the λ (air–fuel ratio) sensor couldn’t properly read the value at idle speed — possibly due to unstable idle, misfire, or sensor limitation — so no accurate lambda reading was recorded there.

    Interpretation of your values​

    • Idle (1740 RPM):
      • HC = 1706 ppm → a bit high (suggests incomplete burning at idle)
      • CO = 1.08 % → within limits
      • λ = OR → sensor couldn’t read
      • O₂ = 9.92 % → quite high → lean combustion
      • CO₂ = 5.80 %
    • 2500 RPM:
      • HC = 426 ppm → much better
      • CO = 0.49 %
      • λ = 1.44 → slightly lean (normal)
      • O₂ = 6.64 %
      • CO₂ = 8.50 %
    • Overall Status: PASS → the car meets emission standards.
    So, in short, this chart shows your vehicle passed the exhaust emission test, even though the λ value at idle couldn’t be read.
