5. Interpreting Oxygen Sensor Readings

Oxygen sensors play a critical role in monitoring the air-fuel mixture. Understanding their readings can help diagnose issues related to fuel efficiency and emissions.

• Normal Readings: Oxygen sensor readings typically fluctuate between 0.1 and 0.9 volts.
• High Voltage (Rich Mixture): A reading above 0.5 volts indicates a rich air-fuel mixture (too much fuel, not enough air).
• Low Voltage (Lean Mixture): A reading below 0.5 volts indicates a lean air-fuel mixture (too little fuel, too much air).

According to a study by the Society of Automotive Engineers (SAE) on July 2, 2022, faulty oxygen sensors are a common cause of poor fuel economy and increased emissions.

6. Understanding Fuel Trim Values

Fuel trim values indicate the adjustments made by the engine control unit (ECU) to maintain the correct air-fuel ratio. These values are expressed as a percentage and can be short-term or long-term.

• Short-Term Fuel Trim (STFT): Immediate adjustments to the air-fuel ratio.
• Long-Term Fuel Trim (LTFT): Gradual adjustments made over time to compensate for persistent imbalances.

Values between -10% and +10% are generally considered normal. Higher positive values suggest a lean condition, while higher negative values indicate a rich condition.
