2004 Honda Civic P0730 Fault: Vehicle Stays in Second Gear Regardless of Selection

Model: 2004 Honda Civic Fault Code: P0730 Posted: 2016-12-10 13:04

My 2004 Honda Civic is stuck in second gear no matter which gear I select—reverse, drive, or neutral all result in drive mode. Only when the vehicle is in park does it not engage drive. The OBD-II diagnostic tool shows a P0730 code indicating an incorrect gear ratio. What could be causing this issue? Is there a specific component or system that needs to be checked?

The vehicle has likely entered limp mode due to the P0730 fault. Correcting the gear ratio issue should restore full functionality. It's recommended to measure the pressure of the first, second, third, and fourth clutches. Check whether each clutch pressure falls within the manufacturer's service limits. This will help determine the next troubleshooting step.
