Additional Notes:
- Provides accurate, real-time air-to-fuel ratio in the engine combustion chamber by measuring oxygen content in the exhaust.
- Requires voltage input from an industry-standard narrow-band oxygen sensor to operate properly.
- Each LED light bar represents 0.1 Volts input from the sensor.
- Two red, two yellow, and one green LED represent approximately 14:7:1 air-to-fuel mixture, which is the chemically correct ratio and the point of lowest emissions.
- All light bars displayed means vehicle is running full rich.
- One or Two red bars means vehicle is running lean.
- Figures on the gauge should be used as a reference point for tuning and evaluation.
- Air/Fuel ratio will continually fluctuate in a computer-equipped vehicle as the computer rapidly adjusts air-fuel ratio to sustain the point of lowest emissions.
- Some oxygen sensors may experience a short lag before the gauge begins functioning as operating temperatures are reached.
- If your vehicle’s performance decreases and gauge becomes sluggish, it’s possible that your oxygen sensor isn’t working properly.
