P2422 DODGE code

The P2422 diagnostic trouble code is an indication that the vent valve of the evaporative emissions control system (EVAP) is stuck closed.

Where is the evaporative emissions vent control valve?

In most cars, the EVAP vent valve is located underneath the vehicle, close to or at the charcoal canister near the fuel tank, see the photo. For that reason, it often fails due to corrosion. The most common problem with the vent valve is when it sticks open or fails.

How does a canister vent valve solenoid work?

The Vent Solenoid is a normally open valve that is commanded closed to seal the EVAP system and stop air flow into the charcoal canister. The Purge Solenoid is normally closed but is opened by the PCM to allow manifold vacuum in the EVAP system — thus drawing fuel vapours from the EVAP system.

What is EVAP CVS?

The solenoid based actuators are designed to meet OBD evaporative fuel emissions system requirements. They come in ported and integrated versions and are adaptable to different port directions and connections. Stoneridge also carries dust filters for the CVS family.

How much does it cost to replace evaporative emissions purge control valve?

Expect to pay anywhere from $80 to $200 in total. The part will typically cost anywhere from $30 to $120, while the labor costs will be right around $50 to $80. Then, of course, there are fees and taxes added on to this price too.

How do you fix evaporative emission system leak detected?

If you see a P0442 evaporative emission system leak detected code, you may be able to resolve the problem without much effort. The easiest solution may be to remove and reaffix the gas cap. Once you do, clear the code on the OBD-II diagnostic scanner and drive for a few days.

What are the symptoms of a bad vapor canister vent solenoid?

Symptoms of a Bad or Failing Canister Purge Solenoid

What happens when EVAP vent solenoid goes bad?

If the EVAP vent solenoid fails, it may not be able to properly vent and release the pressure from the vehicle’s fuel tank properly. This may result in excessive pressure building up, and then escaping when the fuel tank is opened.
