TSB : Conditions For Setting DTC

Details

No Throttle Position (TP) sensor, Intake Air Temperature (IAT) sensor or Manifold Absolute Pressure (MAP) sensor DTCs are stored. Barometric (BARO) pressure is 70 kPa or more. Engine speed is less than 1200 RPM. Fuel level is between 15-85 percent. Vehicle speed is less than 3 MPH (5 km/h). DTC P0440 diagnostic test has passed. System voltage is normal. Start-up engine coolant temperature and start-up intake temperature are 39-93°F (4-34°C). The difference for start-up intake air temperature and current intake air temperature is below 54°F (12°C). Engine coolant temperature is steady, changing below 13°F (7°C). Intake air temperature is steady, changing below 13°F (7°C). Throttle position is below 3 percent. Ignition voltage is between 11V and 16V. Map value is steady, changing less than 2 kPa. Fuel level is between 15 percent and 85 percent. The test starts within 6 minutes after engine started. The test is complete within 10 minutes after tank vacuum drawn. A vacuum decay rate for 10 seconds is more than threshold value.
