How to Diagnose and Fix Bad Purge Valve Noise

AvatarByCarl Frisch

A bad purge valve noise is a sound that is usually heard when a car’s engine is running. It is usually caused by a faulty or clogged purge valve, which is located in the engine’s intake system. The purpose of the purge valve is to allow the pressure in the intake system to be released when the engine is not running, preventing backfires and stalling. If the purge valve becomes clogged or stuck, it can cause an excessive amount of pressure build-up in the intake system, leading to a loud and unpleasant noise.

In order to fix this issue, it is necessary to remove and clean out the purge valve. This involves removing any buildup of dirt and debris from around the valve and then reinstalling it back into its place in the engine. If this does not solve the problem, then a new purge valve may need to be purchased and installed in order for your car to run properly again.
