  • Page 125 Diagnostic Trouble Code (DTC) Detecting Criteria GENERAL DESCRIPTION • Tank Pressure Switching Solenoid One of the atmospheric pressure switching solenoid valves is connected to fuel tank pressure sensor and the other is released to atmosphere. The passage to fuel tank pressure sensor is usually released to atmosphere because the solenoid is set to OFF, but the solenoid which is set to ON closes the passage open to atmo- sphere.
  • Page 126 Diagnostic Trouble Code (DTC) Detecting Criteria GENERAL DESCRIPTION • Purpose of this solenoid Fuel tank pressure sensor detects the difference between the atmospheric air pressure and the tank pres- sure and the ECM monitors the pressure difference. Even if the tank pressure is constant, the atmospheric air pressure varies depending on the driving height, and the pressure signal transmitted to ECM will change.
  • Page 127 Diagnostic Trouble Code (DTC) Detecting Criteria GENERAL DESCRIPTION Especially, in the small leakage [0.5 mm (0.02 in)], minute change in the tank pressure has to be detected.
