DTC Set Conditions
- Test Conditions A: At Start Up - The fuel level sensor output voltage is 2.4-3.7 volts when the engine starts (i.e. the amount of remaining fuel is 40-85%). Intake air temperature is 91°F (33°C) or less when the engine is started. The engine coolant temperature is 91°F (33°C) or less when the engine is started.
- Test Conditions B: For Test To Run - Barometric pressure is above 11 psi (76 kPa). Volumetric efficiency is between 20-80%. The fuel temperature is 91°F (33°C) or less. Fuel tank differential pressure sensor output voltage is 1-4 volts.
- Test Conditions C: For Test To Stop - Engine coolant temperature is less than 68°F (20°C). Intake air temperature is less than 14°F (-10°C). When the evaporative emission purge solenoid and evaporative emission ventilation solenoid are closed, the pressure rises higher: 0.047 psi (324 Pa).
- Judgement Criteria -
Internal pressure of the fuel tank fluctuates 0.177-0.199 psi (1177-1373 Pa) or more in 10 seconds after the tank and vapor line were closed.NOTE: The monitoring time depends on the fuel level and the temperature in the fuel tank (10-14 minutes).
