Code P1AAE GMC Description
The P1AAE diagnostic trouble code for GMC vehicles indicates a Phase Correlation Fault, which typically relates to an issue with the timing of the engine's camshaft and crankshaft. In an internal combustion engine, the camshaft controls the opening and closing of the engine's valves, while the crankshaft converts the up-and-down motion of the pistons into rotational motion. The phase correlation between these two components is critical for proper engine operation.
