P00FE-00: (PCM - VIN Y) FUNCTION INSPECTION USING M-MDS

Step Inspection Results Action
1 PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY 
  • Verify related Service Bulletins, on-line repair information, or Service Information availability.
  • Is any related Information available?
Yes Perform repair or diagnosis according to the available information.
  • If the vehicle is not repaired, go to the next step.
No Go to the next step.
2 PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION 
  • Record the freeze frame data/snapshot data and diagnostic monitoring test results (EVAP system related).
    NOTE:
    • Recording can be facilitated using the screen capture function of the PC.
- Go to the next step.
3 PURPOSE: INSPECT FOR OTHER RELATED DTCs 
  • Perform the DTC inspection for the PCM. (See DTC INSPECTION .)
  • Are any of the following DTCs displayed?
    • P0460-00:
    • P0461-00:
    • P0462-00:
    • P0463-00:
Yes Repair or replace the malfunctioning location according to the applicable DTC troubleshooting.
(See P0460-00: .)
(See P0461-00: .)
(See P0462-00: .)
(See P0463-00: .)
Go to the next step.
No Go to the next step.
4 PURPOSE: VERIFY FUEL TANK PRESSURE SENSOR MEASURED CORRECTLY 
  • Start the engine and idle it.
  • Access the following PCM PIDs using the M-MDS.
    • PRG_DUTY
    • CSTR_VENT_SOL_DUTY
  • Change to the following conditions using the simulation function.
    • PRG_DUTY: 100 %
    • CSTR_VENT_SOL_DUTY: 100 %
  • Access the FTP PID using the M-MDS.
  • Does the negative pressure change when racing the engine?
Yes The fuel tank pressure sensor measures correctly.
  • Go to the next step.
No The possibility of a fuel tank pressure sensor malfunction is high.
  • Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
5 PURPOSE: VERIFY IF PURGE SOLENOID VALVE IS STUCK OPEN 
  • Perform the following procedure to induct barometric pressure to the fuel tank.
  • PRG_DUTY
  • CSTR_VENT_SOL_DUTY
    • Change to the following conditions using the simulation function.
  • PRG_DUTY: 0 %
  • CSTR_VENT_SOL_DUTY: 0 %
    • Access the EVAP_PRES PID using the MMDS.
    NOTE:
    • The displayed PID value is as follows:
      • Approx. 2.6 V (barometric pressure)
  • Perform the following procedure to force drive the CV solenoid valve.
  • PRG_DUTY
  • CSTR_VENT_SOL_DUTY
    • Change to the following conditions using the simulation function.
  • PRG_DUTY: 0 %
  • CSTR_VENT_SOL_DUTY: 100 %
  • Access the FTP PID using the M-MDS.
  • Is the FTP PID value negative pressure?
Yes The possibility of a stuck purge solenoid valve open is high.
  • Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 2.
No The possibility of clogging between fuel tank pressure sensor and fuel tank is high.
  • Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 3.
