Code P1380 Description

The P1380 diagnostic trouble code indicates that a misfire has been detected in the engine, specifically when driving on rough roads. Misfires can occur when there is an incomplete combustion of the air-fuel mixture in one or more cylinders. In this case, the rough road data not being available means that the vehicle's sensors are unable to accurately detect and compensate for the misfire when driving over uneven terrain. This can lead to a rough running engine, decreased fuel efficiency, and potential damage to the catalytic converter over time.
