PURGE VALVE INSPECTION

PROCEDURE

1. INSPECT PURGE VSV (w/ Canister Pump Module)

   
   

   1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 23 to 26 Ω 1 - VSV body ground Always 10 MΩ or higher 2 - VSV body ground 10 MΩ or higher

      If the result is not as specified, replace the purge VSV.

   2. Check the operation of the purge VSV.

      
      
      1. 

         *a	Port E
         *b	Port F
         	Air

         Check that air does not flow from port F when air is applied to port E.

      2. 

         *a	Port E
         *b	Port F
         	Air

         Apply battery voltage to the connector, and check the VSV operation.

         OK
         Measurement Condition Specified Condition Battery positive (+) → Terminal 1 Battery negative (-) → Terminal 2 Air flows from port E to port F

         If the result is not as specified, replace the purge VSV.

2. INSPECT PURGE VSV (w/o Canister Pump Module)

   
   

   1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 23 to 26 Ω 1 - VSV body Always 10 MΩ or higher 2 - VSV body Always 10 MΩ or higher

   2. Check the operation of the purge VSV.

      
      
      1. 

         *a	Port E
         *b	Port F
         *c	Air

         Check that air does not flow from port F when air is applied to port E.

      2. 

         *a	Port E
         *b	Port F
         *c	Terminal 1
         *d	Terminal 2
         *e	Air

         Apply battery voltage between the terminals of purge VSV, and check the purge VSV operation.

         OK
         Measurement Condition Specified Condition Battery positive (+) → Terminal 1 Battery negative (-) → Terminal 2 Air flows from port E to port F
