INSPECTION OF FUEL PRESSURE CONTROL SYSTEM
INSPECT VSV
A. Inspect VSV for Open Circuit
Using an ohmmeter, check that there is continuity between terminals.
Resistance: 30 — 50 Ω
If there is no continuity, replace the VSV.

B. Inspect VSV for Short Circuit
Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.
[DIAGRAM showing "No continuity" measurement between VSV terminal and body]
F11918
C. Inspect VSV Operation
(a) Apply battery voltage across the terminals.
(b) Check that air flows from pipe E to air filter.
