Solving P0446 on Your 2023 Dodge Charger
A P0446 code on your 2023 Dodge Charger indicates an EVAP vent control circuit malfunction. As the final ICE model year for the Charger, the 2023 uses the proven LX platform with Stellantis' NVLD (Natural Vacuum Leak Detection) system. This applies whether you have the 3.6L Pentastar V6, 5.7L HEMI V8, 6.4L Scat Pack, or the supercharged Hellcat.
Under warranty, this is a dealer repair at no cost. With the Charger's ICE production ended, dealer parts availability remains strong.
