Component Tests: Solenoids

WARNING: This page is about a different car, the 2002 Toyota Avalon and 2001 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For circuit reference, see WIRING DIAGRAMS and/or CONNECTOR IDENTIFICATION .

To check solenoid seals, remove suspect solenoid. Connect battery voltage to solenoid. Apply 71 psi (5 kg/cm² ) air pressure to solenoid with battery voltage connected. See Fig 1.
With battery voltage applied, air should pass through solenoid. Disconnect voltage to solenoid. Ensure air does not pass through solenoid. Replace solenoid if defective.
