However, we can talk about common types of drive cycles that *could* be used for testing a 2003 Dodge Durango:
* EPA City/Highway Cycles: These are standardized drive cycles used by the Environmental Protection Agency (EPA) to determine fuel economy ratings. They are highly specific in terms of speed, acceleration, and idle time. These are not typically used by individual car owners. You can find details on the EPA website, but performing these precisely requires specialized equipment.
* OBD-II Drive Cycles: Your Durango's On-Board Diagnostics II (OBD-II) system might have its own internal diagnostic drive cycles to check the readiness of emissions systems. These cycles usually involve a combination of idling, acceleration, and cruising at various speeds for a certain duration. The specific requirements aren't usually published, and the car's computer performs the check automatically. If you're trying to get a specific monitor to complete, performing a varied driving pattern (including highway driving) for several miles is usually sufficient.
* Custom Drive Cycles: For specific testing or diagnostic purposes (like troubleshooting a particular emissions issue), a mechanic or technician might design a custom drive cycle to stress particular systems.
In short: There's no single "drive cycle" to follow. If you're trying to clear emission codes, driving the Durango on a mix of city and highway driving for an extended period (30-60 minutes or more of varied driving) is typically sufficient. If you need a specific cycle for a particular test, consult a repair manual or professional.
