Fuel Pressure Control Solenoid: Testing and Inspection
PROCEDURE
1. Remove Vacuum Switching Valve.
VSV Removal
-
Disconnect the Data Link Connector 1 from the bracket.
-
Disconnect the Vacuum Switching Valve connector.
-
Disconnect the 2 vacuum hoses from the Vacuum Switching Valve.
-
Remove the bolt, Data Link Connector 1 bracket and Vacuum Switching Valve assembly.
-
Remove the screw and Vacuum Switching Valve from the Data Link Connector 1 bracket.
2. Inspect Vacuum Switching Valve for open circuit.
VSV Inspection - Checking Resistance
-
Using an ohmmeter, check that there is continuity between the terminals.
Resistance: 33 - 39 ohms at 20°C (68°F)
-
If there is no continuity, replace the Vacuum Switching Valve.
3. Inspect Vacuum Switching Valve for ground.
VSV Inspection - Checking For Short
-
Using an ohmmeter, check that there is no continuity between each terminal and the body.
-
If there is continuity, replace the Vacuum Switching Valve.
4. Inspect Vacuum Switching Valve operation.
