RAV4 4WD L4-2.0L (3S-FE) (1996)
Vacuum Switching Valve (VSV) for EVAP: Testing and Inspection
1. REMOVE AIR CLEANER CAP ASSEMBLY
2. REMOVE VSV
3. INSPECT VSV
A. Inspect VSV for open circuit
-
Using an ohmmeter, check that there is continuity between the terminals.
Resistance: At 20°C (68°F): 30 - 34 ohms
-
If there is no continuity, replace the VSV.
B. Inspect VSV for ground
-
Using an ohmmeter, check that there is no continuity between each terminal and the body.
-
If there is continuity, replace the VSV.
C. Inspect VSV operation
-
Check that air does not flow from ports E to F.
NOTICE: Never apply more than 60 kPa (0.61 kgf/sq.cm, 8.7 psi) of pressure compressed air to the VSV.
-
Apply battery positive voltage across the terminals.
