Code P1AEA GMC Description

The P1AEA code indicates a fault in the hybrid vehicle's drive motor 2 control module, specifically relating to the voltage sense circuit for the hybrid battery. This code is particularly relevant for vehicles equipped with hybrid powertrains, where the electric motor and battery system play a crucial role in overall vehicle performance and efficiency. The "low voltage" aspect of the code suggests that the control module is detecting a voltage level that is below the expected threshold, which can lead to several operational issues.
