Hi,

The code doesn't seem related to the A/C. It is related to the fuel tank vent valve being stuck open.

As far as the A/C, check to see if there is power to the compressor clutch. The clutch itself may have failed. Also, are you certain the Freon is full? Low pressure will prevent it from turning on as well.

Take a look through this link and let me know if it helps:

Let me know what you find or if you have other questions.

Take care,

Joe

Happy to help. I will watch for your reply. Also, if it is possible, check the static pressure of the system and let me know what it is. Static pressure is when everything is off. If you can, let me know both the high and low-pressure readings.

Take care,

Joe
