Code P1247 Mitsubishi Description

The P1247 code in Mitsubishi vehicles indicates a problem with the Automatic Transmission (A/T) Plausibility. This means that the engine control module (ECM) has detected a discrepancy between the signals from the transmission and engine speed sensors, leading to an inconsistency in the data being received. This can result in issues with shifting gears, hesitation, abnormal engine behavior, and potentially even transmission damage if left unaddressed.
