Decode The Mystery: Understanding The P0797 Fault Code
The fault code P0797 indicates a discrepancy between the gear required by the Engine Control Module (ECM) and the actual gear being used while driving.
This means that the ECM is expecting the vehicle to be in a specific gear, but the actual gear being used does not match this expectation. This can lead to issues with the vehicle’s performance and can cause problems with shifting gears smoothly. It is important to address this fault code promptly to ensure proper functioning of the transmission system.
FAQ
The fault code P0797 in an automobile can be caused by various factors.
