Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
DK:DTC P1443 VENT CONTROL SOLENOID VALVE FUNCTION PROBLEM
1. OUTLINE OF DIAGNOSIS
Detect the abnormal functioning (stuck closed) of drain valve.
Judge as NG when fuel tank pressure is low.
2. COMPONENT DESCRIPTION
The drain valve adjusts the pressure in the canister by introducing/extracting air when pressure differences
occur in the canister with the atmospheric pressure.

or more.
Time Needed for Diagnosis: 0.3 second
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Normality Judgment

B: CAUTION
•Wear work clothing, including a cap, protective
goggles and protective shoes during operation.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust and dirt.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
•Be careful not to burn yourself, because each
part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shop jacks or rigid racks at the specified
points.
•Before disconnecting connectors of sensors or
units, be sure to disconnect the ground cable from
the battery.
