P115E - THROTTLE ACTUATOR CONTROL (TAC) THROTTLE BODY AIR FLOW TRIM AT MAX LIMIT
| Description: During idle, the PCM monitors the throttle angle and airflow. If the airflow is determined to be less than expected, the PCM adjusts the throttle angle to compensate. The airflow reduction is typically the result of engine deposit buildup around the throttle plate. This DTC sets when the PCM has reached the maximum allowed compensation and is no longer able to compensate for the buildup. | |||
