Checking for vacuum loss (loaded condition)
WARNING: This page is about a different car, the 2005 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.
- Start the engine.
- Depress the brake pedal with a force of 200 N {20.4 kgf, 44.9 lbf}.
- With the brake pedal depressed, turn off the engine when the vacuum gauge reaches 68 kPa {510 mmHg, 20.1 inHg}.
- Within 15 s right after stopping the engine, measure the lowest amount of vacuum.
- If the lowest amount is 3.3 kPa {25 mmHg, 1.0 inHg} or less, the system is normal.
