DETAILS ON DTC DESCRIPTION
| DESCRIPTION |
Evaporator system: clogging between fuel tank and fuel tank pressure sensor |
| DETECTION CONDITION |
Determination conditions |
- The following conditions are all met while the vehicle is being driven:
- If negative pressure is inducted to the fuel tank via the intake manifold by the operation of the purge solenoid valve with the fuel tank in a sealed condition and the target negative pressure is reached within a shorter period of time than the estimated time.
- When the barometric pressure in the fuel tank is fixed and the purge solenoid valve is opened/closed, the negative pressure fluctuation in the fuel tank generates negative pressure exceeding the threshold.
|
| Preconditions |
- Period ignition is switched off before engine is started: 120 min or more
- Engine coolant temperature at engine start: 1.67-43.33 °C {35.1-109.9 °F}
- Time elapsed from engine start: 5.5-90 min
- Fuel level in fuel tank: 10-90 %
- Desired ambient air temperature: 4.4-43.3 °C {40-109 °F}
- Barometric pressure: 72.23 Pa {7.365 kgf/m2
, 0.01048 psi} or more
- Charging efficiency: 3-65 %
- Vehicle speed: 64-144.8 km/h {40.00-89.97 mph}
- Purge flow amount: 15 l/min or more
