Solving P0446 on Your 2024 Dodge Hornet
A P0446 code on your 2024 Dodge Hornet signals an EVAP vent control circuit malfunction. The Hornet uses a platform shared with the Alfa Romeo Tonale, available with the 2.0L turbo engine (GT) or 1.3L turbo plug-in hybrid (R/T). The EVAP system uses a PCM-controlled vent solenoid—a different architecture from traditional Dodge vehicles.
Under full warranty, this is a no-cost dealer repair.
