Check Valve Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2001 Honda Prelude, 2001 Honda Odyssey, 2001 Honda Insight, 2001 Honda Civic, and 2001 Honda CR-V. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Brake booster check valve is built in brake booster vacuum hose.

Disconnect power brake unit vacuum hose at booster. Start engine, and allow it to idle. Ensure vacuum is available at booster end of hose. If vacuum is not available, vacuum source or check valve is faulty. Repair vacuum source or replace brake booster vacuum hose and check valve, and retest.
