Do you ever wonder why your car’s engine warning light keeps coming on, or why your vehicle is losing power and fuel efficiency?

The problem could be due to a dirty or clogged purge solenoid valve. This small but crucial component of your car’s emission system can have a significant impact on your vehicle’s performance and can even cause long-term damage if left unattended.

Fortunately, cleaning the purge solenoid valve is a simple and affordable task that can be done at home, with no special tools or skills required.

In this blog post, we’ll guide you through the steps on how to clean purge solenoid valve. So, if you’re looking to improve your car’s performance, reduce emissions, and save money on costly repairs, read on!

  • Step 1: Just spray the mass air flow sensor cleaner with a closed valve technique
  • Step 2: Connect a 12volts battery source to the valve’s terminal and spray again with an open valve technique
  • Step 3: Leave the valve to dry
  • Step 4: Once the valve is dry, ensure that it’s completely dry by blowing a vacuum hand pump over it to dry up any traces of the mass air flow sensor cleaner.

Once you’re satisfied that it’s totally dry, reinstall your purge valve solenoid, restart your car, and see if the check engine light is still on.

At this point, the check engine light would definitely go off and your car performance should go back to normal.


In conclusion, cleaning your purge solenoid valve is a crucial step in maintaining the health and longevity of your vehicle’s emissions system. You can save yourself time and money in the long run while also reducing your carbon footprint by following the steps outlined in this post.

However, beyond the practical benefits of cleaning your purge solenoid valve, it’s worth considering the bigger picture. The emissions from our vehicles have a significant impact on the environment, contributing to issues like air pollution and climate change.
