P0605 ISUZU OBD Code Description

The Engine Control Module (ECM) continuously monitors its own internal memory status, internal circuits, and output signals transmitted to the throttle actuator. This self-check insures that the ECM is functioning properly. If any malfunction is detected, the ECM sets the P0605 code and illuminates the MIL.
