Code P1512 Chevrolet Description

The P1512 code for Chevrolet vehicles indicates that the Intake Manifold Runner Control (IMRC) is stuck closed.

When the control is stuck closed, it means that the intake manifold runners are not able to adjust properly, leading to a restriction in airflow and potentially causing a decrease in engine performance and efficiency.
