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 and engine coolant temperature are 97°F (36°C) or less when the engine is started.
Test Conditions B: For Test to Run - Barometric pressure is above 11 psi (76 kPa). 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).

NOTE: The monitoring time depends on the fuel level and the temperature in the fuel tank (10-14 minutes).

Judgement Criteria Internal pressure of the fuel tank fluctuate 0.171-0.199 psi (1,177-1,373 Pa) or more in 10 seconds after the tank and vapor lines were closed.
