Fuel Pressure Control Solenoid: Testing and Inspection
Component Inspection
VSV FOR FUEL PRESSURE CONTROL INSPECTION
1. Remove air intake chamber assembly.
2. Inspect VSV
3. Disconnect vacuum hoses and connector
4. Inspect VSV for open circuit
Using an ohmmeter, check that there is continuity between the terminals.
Resistance: At 20°C (68°F) 37 - 44 ohms.
If there is no continuity. replace the VSV.
5. 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.
6. Inspect VSV operation
(a) Check that the air flows from port E to G.
(b) Apply battery voltage across the terminals.
