The P151E fault code refers to a problem with the active grille air shutter system in a vehicle. This system is responsible for closing or opening the shutters in the front grille to optimize aerodynamics and control airflow. The Engine Control Module (ECM), ignition, and ground circuits work together to operate the active grille air shutter actuators.

If the conditions for opening the shutters are met, the ECM commands the actuators to open one or both shutters. In the case of the dual active grille air shutter system, there are two aero shutter mechanisms in the front grille.

The ECM determines the state of the shutters based on various vehicle conditions such as speed, coolant temperature, fan state, and ambient temperature. Through communication on the LIN Bus, the ECM can individually command each shutter to open or close. To power the actuators, an ignition circuit is activated when the key is in the RUN position. It may take up to 13 minutes of driving at speeds over 41 kmh (25 mph) for a shutter to start moving.

However, if the system detects low ambient temperature, the shutters will remain closed. If there is a LIN Bus Communication Malfunction, the Diagnostic Trouble Code (DTC) P151E will be set.

This code specifically refers to the Active Grille Air Shutter Actuator 1 Signal Message Counter I.

What are the possible causes of the automobile fault code p151e?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P151E could be the culprit.
