Diagnostic Reference Values:
Diagnostic Reference Values:
- Reference values are based on engine at normal operating temperature.
- Key On Engine Off (KOEO) and Hot Idle test values are recorded with vehicle in "NEUTRAL".
- Ignition timing values assume base timing is set correctly (10 degrees before top dead center).
- Use one gear below top for the 30 mph values and top gear for the 55 mph values
- Reference values shown may differ between vehicles due to various factors:
- Component tolerances
- Driving conditions
- Weather
These values were recorded at approximately 600 feet above sea level with ambient temperatures 50-70 degrees F.
Some Electronic Engine Controls (EEC) devices such as Intake Air Temperature (IAT), Engine Coolant Temperature (ECT) are temperature dependent and values may vary. Other Values such as Idle Air Control (IAC) and Injector Pulsewidth (INJ) are calibration dependent and may vary also.
