A Vapour Canister Purge Valve plays an important role in running of your car. It is a vital and significant component that was firmly for good reasons.
The Central Computer system controls when to open the valve and when to close. The functioning is based on the circumstances and the utilisation of the Engine.
During the good old days, there is no central computer functioning systems that can help the valve work according to the sensors. So, our predecessors used to control the valve based upon the amount of vapour gathers inti the holder section of the valve.
Coming to today’s world, The purge valves can get contaminate with debris and dust that makes the valve stuck which will eventually cause an evaporation leak inside the manifold.
The primary agenda of inserting a purge valve inside the engine is to avoid contagious gases emitting into the atmosphere that could cause huge non-repairable damage to the climate.
The most important part of the evaporation system controlled by computer. Which is to allow the vapour to get into the intake and not to the atmosphere.

- The Vaccum should hold for at least 5 minutes to determine a good functioning purge valve.
- If the vacuum needle on the gauge drops dead after a few minutes then the purge valve is bad and needs to be taken care of.
This will determine if the purge canister valve is working properly or not.
4. Failing In Emission Test:
As we discussed before, the purge valve will confine the harmful gases upon releasing on to the atmosphere you will fail in the Environmental test of you have a bad purge. The toxic hydrocarbons gases will enter the test kit thus failing the result.
5. Gas Cap:
The Gas cap not being close properly after filling up your tank can also cause damage in the purge valve. So, before rushing to the mechanic and offering him money blindly, make sure you fixed the gas cap nice and tight. IF not, do it and commence your journey without a tiny bit of trouble.
