NOTE:
- Engine coolant temperature must be greater than 10°C (50°F) to pass the KOEO Self-Test and greater than 82°C (180°F) to pass the KOER Self-Test. To accomplish this, the engine must be at normal operating temperature.
- Ambient temperature must be above 10°C (50°F) to receive acceptable input from the Intake Air Temperature (IAT) sensor.
- Voltage values were calculated for VREF = 5.0 volts. These values can vary 15 percent due to sensor and VREF variations.
