  • Importance: RPM indicates how fast the engine’s crankshaft is rotating. Monitoring RPM helps ensure the engine operates within its optimal range.
  • Normal Range: The normal idle RPM for most vehicles is between 600 and 1000 RPM.
  • Abnormal Readings: High RPM at idle can indicate a vacuum leak or a malfunctioning throttle position sensor. Low RPM can suggest a dirty throttle body or a faulty idle air control valve.
• Coolant Temperature:
  • Importance: Coolant temperature is critical for engine health. Overheating can cause severe damage, while running too cold can reduce efficiency.
  • Normal Range: The normal operating temperature for most vehicles is between 195°F and 220°F (90°C and 104°C).
  • Abnormal Readings: High coolant temperatures can indicate a failing thermostat, a clogged radiator, or a coolant leak. Low temperatures can suggest a stuck-open thermostat.
• Oxygen Sensor Readings:
  • Importance: Oxygen sensors measure the amount of oxygen in the exhaust gases, providing feedback to the ECU for fuel mixture adjustments.
  • Normal Range: Oxygen sensor readings should fluctuate rapidly between 0.1 and 0.9 volts.
  • Abnormal Readings: Consistently high or low readings can indicate a faulty oxygen sensor, a vacuum leak, or a fuel system problem.
• Fuel Trim:
  • Importance: Fuel trim values indicate how much the ECU is adjusting the fuel mixture to compensate for deviations from the ideal air-fuel ratio.
  • Normal Range: Short-term fuel trim (STFT) and long-term fuel trim (LTFT) values should ideally be close to 0%. Values between -10% and +10% are generally considered acceptable.
  • Abnormal Readings: High positive fuel trim values indicate that the ECU is adding fuel to compensate for a lean condition (too much air). High negative values indicate that the ECU is reducing fuel to compensate for a rich condition (too much fuel).
• Intake Air Temperature (IAT):
  • Importance: IAT affects engine performance and fuel efficiency. High IAT can reduce engine power, while low IAT can cause poor combustion.
  • Normal Range: IAT should be close to the ambient air temperature.

  • Normal Range: MAF readings vary depending on engine size and RPM.
  • Abnormal Readings: Low MAF readings can indicate a clogged air filter or a faulty MAF sensor. High readings can suggest a vacuum leak.
• Throttle Position:
  • Importance: Throttle position indicates how far the throttle plate is open, which controls the amount of air entering the engine.
  • Normal Range: Throttle position should be at 0% at idle and increase linearly as the accelerator pedal is pressed.
  • Abnormal Readings: Erratic or inconsistent throttle position readings can indicate a faulty throttle position sensor.
• Vehicle Speed:
  • Importance: Vehicle speed is a basic parameter that can be used to verify the accuracy of the speedometer and identify issues with the transmission or ABS system.
  • Normal Range: Vehicle speed should match the reading on the speedometer.
  • Abnormal Readings: Discrepancies between the OBD2 reading and the speedometer can indicate a faulty speed sensor or a transmission problem.
• Load Value:
  • Importance: Load value indicates the percentage of maximum engine load, which is used to calculate fuel consumption and adjust engine parameters.
  • Normal Range: Load value varies depending on driving conditions.
  • Abnormal Readings: High load values can indicate that the engine is working harder than it should, which can lead to increased fuel consumption and wear.
• Ignition Timing Advance:
  • Importance: Ignition timing advance refers to how far ahead of top dead center (TDC) the spark plugs fire.
  • Normal Range: Varies with engine type and operating conditions. Usually specified in the vehicle’s service manual.
  • Abnormal Readings: Over-advanced or retarded timing can cause poor performance, knocking, or potential engine damage.
