What is the P0442 Error Code?
The P0442 error code is part of the onboard diagnostics (OBD) system in vehicles.

This system includes components such as the gas cap, purge valve, charcoal canister, and various hoses.
Common Symptoms of the P0442 Error Code
When your Dodge Charger displays the P0442 error code, you might notice the following symptoms:
- Check Engine Light: The most common indicator is the check engine light on your dashboard.
- Fuel Odor: You may smell fuel due to vapors escaping from the EVAP system.
Step-by-Step Guide to Diagnose and Fix the P0442 Error Code

Step 2: Inspect EVAP System Hoses
