Investigating P0446 on Your 2022 Dodge Hornet
A P0446 code on your 2022 Dodge Hornet indicates an EVAP vent control circuit malfunction. The Hornet is built on a platform shared with the Alfa Romeo Tonale, featuring a 2.0L turbocharged four-cylinder engine. Unlike traditional Dodge vehicles that use the NVLD system, the Hornet's European-derived architecture employs an updated EVAP management system with a vent solenoid controlled by the PCM.
Check your warranty status—the basic warranty (3yr/36k) may still apply depending on purchase date and mileage.
Clues and Symptoms
- Check engine light with P0446 stored
- Fuel fill difficulty
- EVAP readiness monitor incomplete
- Possible fuel odor
Top Suspects
- Vent Solenoid Failure (High Likelihood): The vent solenoid on the Hornet's platform can fail electrically or mechanically. Replacement costs $140–$260 if not warranty-covered.
- PCM Software Calibration (High Likelihood): Early-production EVAP monitoring calibration may need updating. A dealer reflash resolves this.
- Purge Solenoid Malfunction (Medium Likelihood): A sticking purge valve disrupts EVAP flow. Replacement runs $120–$220.
- Vent Solenoid Wiring or Connector (Medium Likelihood): Connector or harness issue at the vent solenoid. Repair costs $80–$180.
- Gas Cap Seal (Low Likelihood): Worn seal. Replacement is $10–$25.
How to Investigate
The Hornet's platform is different from traditional Dodge vehicles. wiTECH diagnostics at a dealer provide the most accurate testing for this platform. For DIY, start with the gas cap seal and scan for all stored codes. Note that many independent shops may be less familiar with the Hornet's Alfa Romeo-derived architecture.
Warranty and Cost
Check if the basic warranty (3yr/36k) is still active. The powertrain warranty (5yr/60k) and federal emissions warranty (8yr/80k) provide extended coverage. Under warranty, all repairs are free. Out of pocket: $120–$260.
Safe to Drive?
Yes. P0446 is an emissions circuit code that doesn't affect your Hornet's engine performance, transmission, AWD system, or safety features.
