Code C2774 Description

The diagnostic trouble code C2774 indicates a pedal travel sensor plausibility failure. This means that the vehicle's onboard computer has detected a discrepancy between the expected and actual values from the pedal travel sensor. The pedal travel sensor is responsible for monitoring the position and movement of the accelerator pedal. When a plausibility failure occurs, it can lead to incorrect signals being sent to the engine control module, affecting the vehicle's performance and drivability.
