P25A3Engine Hood Open

P25A3 is a generic body/comfort code indicating that the engine control module (ECM) or body control module (BCM) has detected the engine hood is open when the vehicle logic expects it to be closed. The module monitors a hood ajar switch or the hood position input from the latch, and it sets this code when the circuit or switch reports an open hood condition outside of normal service access.
