ase 8 engine performance aut-183/aut- the pcm of an engine is comprised of all of the following parts except: a. a memory and storage section. b. a sensor input/output signal processing section. c. a data processing section. d. a feedback control section.

Explanation:

An engine's Powertrain Control Module (PCM) core components include memory/storage (for calibration data), sensor I/O signal processing (to interface with vehicle sensors/actuators), and data processing (the main computing unit). Feedback control is a function the PCM performs using its components, not a distinct physical section of the module itself.

Answer:

d. A feedback control section.
