What Is an EVAP Purge Valve?
The EVAP purge valve is a common (and cheap) check-engine-light cause. A Cranbourne West specialist explains.
What it is & what it does
The EVAP (evaporative emissions) system captures fuel vapour from the tank and feeds it back to the engine to burn, instead of releasing it. The purge valve controls when those vapours are drawn in.
A loose fuel cap is the simplest EVAP fault; the purge valve is another common one.
Signs of trouble & how we help
A stuck purge valve (or EVAP leak) causes a check-engine light, sometimes rough running or a fuel smell. It’s usually an inexpensive valve once diagnosed — but the system must be tested to confirm.
We read the EVAP codes and smoke/pressure-test the system to find the exact fault.
