Code P0506 2016 Honda CR-V Description

A target idle speed that meets the engine operating conditions (coolant temperature, A/C ON or OFF, etc.) is stored in the Powertrain Control Module (PCM). The PCM monitors and controls the idle speed so that the actual idle speed is equal to the target idle speed. If the actual idle speed varies beyond a specified value from the target speed over a certain period of time, the PCM detects a malfunction in the idle speed control system and stores a Diagnostic Trouble Code (DTC). The DTC will be set when the actual idle speed is 100 rpm less than the target idle speed for at least 20 seconds.
