P00FE-00: (PCM - VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location 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
  • Evaporative gas flow amount: Exceeds 10, 000 cm 3 /min or fuel tank vacuum is high
  • Fuel tank pressure: -4, 340.2-4, 030.1 Pa {-442.57-410.95 kgf/m 2 , -0.62949-0.58452 psi} *1
  • IAT sensor No. 1: 4.44-43.33°C {40.0-109.9°F} *1
  • Vehicle speed: 64-145 km/h {40.0-90.0 mph} *1
  • Barometric pressure: 72.23 kPa {0.7365 kgf/cm 2 , 10.48 psi} or more *1
  • Period ignition is switched off before engine starts: 210 min or more
  • Fuel level in fuel tank: 15-85 % *1
  • Minimum value of intake manifold vacuum: 4 kPa {0.04 kgf/cm 2 , 0.6 psi} or more
  • Minimum value of intake air amount: more than 2 g/sec
  • Battery voltage: more than 11 V
  • The following DTCs are not detected: *1
    • ECT sensor No. 1: P0117-00: and P0118-00:
    • TP sensor No. 1: P0122-00: and P0123-00:
    • TP sensor No. 2: P0222-00: and P0223-00:
    • Purge solenoid valve: P0443-00:
    • CV solenoid valve: P0446-00:
    • MAF sensor: P0100-00:
    • Fuel tank pressure sensor: P0451-00:, P0452-00: and P0453-00:
    • IAT sensor No. 1: P0110-00:
    • MAP sensor: P0107-00: and P0108-00:
    • BARO sensor: P2226-00:, P2228-00: and P2229-00:
    • VSS signal: P0500-00:
    • Fuel gauge sender unit: P0460-00:, P0461-00:, P0462-00: and P0463-00:
