Rectifying Air Leakage After the Flap Valve

Rectifying Air Leakage After The Flap Valve







Check and rectify if:
- the EVAP purge valve circuit is blocked
- faulty brake servo
- the crank case ventilation is blocked
- there is an air leak present in the vacuum hoses.

- Pinch off one hose at a time and observe the diagnostic tool's display to determine whether a leak occurs. It is OK if crankcase ventilation gives an increment of about 5% via the thin hose.

The other hoses must not give any noticeable increment. Note that the evap canister purge valve's electrical connection must be disconnected for this check.

Plug in the connector:
