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

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}(1)
  • Time elapsed from engine start: 5.5-90 min
  • Fuel level in fuel tank: 10-90%(1)
  • Desired ambient air temperature: 4.4-43.3 °C {40-109 °F}(1)
  • Barometric pressure: 72.23 Pa {7.365 kgf/m2 , 0.01048 psi} or more(1)
  • Charging efficiency: 3-65%(1)
  • Vehicle speed: 64-144.8 km/h {40.00-89.97 mph}(1)
  • Purge flow amount: 15 l/min or more

(1) Standard can be verified by displaying PIDs using M-MDS
Malfunction determination period
  • 75 s period
Drive cycle
Self test type
  • CMDTC self test
Sensor used
  • Fuel tank pressure sensor
FAIL-SAFE FUNCTION

VEHICLE STATUS WHEN DTCs ARE OUTPUT
  • Illuminates check engine light.
POSSIBLE CAUSE
  • Erratic signal to PCM
    • Fuel tank pressure sensor signal malfunction
  • Fuel gauge sender unit malfunction
  • Fuel tank pressure sensor malfunction
  • Clogging between fuel tank and fuel tank pressure sensor
  • Fuel shut-off valve malfunction
  • Rollover valve malfunction
  • Purge solenoid valve malfunction
  • PCM malfunction
