So when i plugged in the thing that reads why my service engine soon light was on it came up with the code in the title. In the book it says evaporative emissions controll system vent controll circuit malfunction. Does anyone know what the problem is? Thanks for your help.

 

Monitors the canister vent (CV) solenoid circuit for an electrical failure. The test fails when
the signal moves outside the minimum or maximum allowable calibrated parameters for a
specified canister vent duty cycle by powertrain control module (PCM) command.
Possible
Causes:
- VPWR circuit open
- KAPWR circuit open (vehicles equipped with engine off natural vacuum (EONV)
EVAP leak check monitor)
- CV solenoid circuit shorted to PWR GND or CHASSIS GND
- Damaged CV solenoid
- CV solenoid circuit open
- CV solenoid circuit shorted to VPWR
- CV solenoid circuit shorted to KAPWR (vehicles equipped with engine off natural
vacuum (EONV) EVAP leak check monitor)
- Damaged PCM

Diagnostic
Aids:
To verify normal functioning, monitor the EVAP canister vent solenoid signal PID EVAPCV
and the signal voltage (PCM control side). With the valve open, EVAPCV indicates 0% duty
cycle and a voltage approximately equal to battery voltage. When the valve is commanded
fully closed, EVAPCV indicates 100% duty cycle, and a minimum voltage drop of 4 volts is
normal. Output test mode may be used to switch output on/off to verify function.

If you determine the solenoid is bad I have an extra one (used) that I would sell.
