P115E Meaning
During idle, the Powertrain Control Module (PCM) monitors throttle angle and airflow. If the airflow is determined to be lower than expected, the PCM adjusts the throttle angle to compensate. The reduced airflow is typically the result of deposit buildup in the engine around the throttle body. Code P115E indicates that the PCM has reached the maximum allowable compensation and is no longer able to compensate for the buildup.
