^ The following DTCs are not detected: DTCs related to ECT sensor and IAT sensor (other than P0111)

Non-EVAP-leak-check model:
^ Intake air temperature at engine start: -10 °C (14 °F) to 80 °C (176 °F)
^ Intake air temperature: -10 °C (14 °F) to 70 °C (158 °F)
^ Engine coolant temperature: 70 °C (158 °F) to 150 °C (302 °F)
^ Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
^ The following DTCs are not detected: DTCs related to ECT sensor, IAT sensor (other than P0111) and barometric pressure sensor
