The powertrain control module (PCM) detects a blockage on the vent line by two phases:

• Phase 1

  The fuel vapor containment valve is opened for a short time, and the VENT blockage is determined by the change in the tank internal pressure. If there is a pressure change in the tank, the PCM determines as normal. If there is no pressure change, there is a possibility of a VENT blockage failure or the pressure in the tank is not applied, and the detection moves to phase 2.

• Phase 2

  If an abnormality is found in phase 1, the PCM detects a blockage of the vent line by estimating the volume of space in the evaporative emission (EVAP) system. Phase 2 is performed after the vehicle has stopped for a period of time, and if the volume of space is large, the EVAP leak check module is closed and decompressed by purging. If the volume of space is small, the PCM detects a malfunction and stores a DTC.

Malfunction Threshold 

• Phase 1
  • When the change in the pressure is 1 kPa (0.35 inHg, 9 mmHg) or more, or -2 kPa (-0.47 inHg, -12 mmHg) or less.
• Phase 2
  • When the calculated volume of space in the EVAP system is 3.5 L (0.92 US gal) or less.

Possible Cause 

Confirmation Procedure 

Operating Condition 

• With an average fuel level [Fuel Level (Average)] of 85 % or less, turn the vehicle to the ON mode, and wait for at least 10 minutes. Drive the vehicle for 7 miles (10 km/h) or more after refueling.
• Turn the vehicle to the OFF (LOCK) mode, and wait for at least 5 hours.
• After the PCM wakes up and wait at least 18 minutes 55 seconds.

• When you have difficulty duplicating the DTC because of road conditions and traffic situations, repeat the driving pattern several times.
• Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

With the HDS 

Do the EVAP TEST in the INSPECTION MENU with the HDS.

Diagnosis Details 

Conditions for setting the DTC 

When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC 

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command or by disconnecting the 12 volt battery.
