2012 VW Jetta GLI; OBD Code P2440

Hi,

Have you ever addressed this Code for this model in any of your videos?  If not, can you?  Or can you please provide a troubleshooting checklist?  

As for symptoms, I am not noticing any problems with how the vehicle is operating.  Maybe a little less gas mileage, but really hard to say.

As for troubleshooting, I cleared the code and it came back after about 2 days.  Next, I checked the fuses in the engine bay, and none are blown.  Next, I also tried to check all the electrical connections for the secondary air system (although, to be honest, it is hard to determine exactly what is what).

Thanks for any help.

P2440: Secondary Air Injection System Switching Valve Stuck Open Bank1 https://www.engine-codes.com/p2440_volkswagen.html

The main purpose of this code is the vacuum switching valve (VSV). It could have gone bad.

Other things to check:

  1. Pressure Sensor
  2. Air Switching Valve
