Investigating P0446 on Your 2022 Genesis GV70
A P0446 code on your 2022 Genesis GV70 indicates an EVAP vent control circuit malfunction. The GV70 uses the JK1 platform with a 2.5L turbo four-cylinder or 3.5L twin-turbo V6. Genesis uses a Canister Close Valve (CCV) for vent control and a Purge Control Solenoid Valve (PCSV) for purge management.
Genesis' industry-leading warranty (5yr/60k basic + 10yr/100k powertrain) should fully cover this repair with complimentary pickup and delivery.
Clues and Symptoms

Top Suspects
- CCV Failure (High Likelihood): The Canister Close Valve controls vent airflow. First-year model may have early production variation. Replacement costs $120–$240 if not warranty-covered.
- PCSV Malfunction (High Likelihood): Sticking purge valve disrupts EVAP flow. Replacement runs $110–$220.
- FTPS Signal Issue (Medium Likelihood): Fuel Tank Pressure Sensor provides faulty readings. Replacement costs $100–$200.
- CCV Wiring or Connector (Medium Likelihood): Connector issue. Repair costs $70–$160.
- Gas Cap Seal (Low Likelihood): Worn seal. Replacement is $12–$25.
