Have you ever wondered, “What is this car really thinking?” The Electronic Control Module (ECM) in our Fieros takes information from driver inputs and vehicle sensors to determine the optimum engine settings for performance and exhaust emissions. Though not as simple as a carburetor, the Fiero’s OBD-I (On-Board Diagnostic) system is much less complex than the OBD-II cars we drive today.

Join us for a discussion about the sensors and control systems used to communicate with the Fiero’s ECM. This knowledge is useful background information in diagnosing drivability problems like a rough idle. Our presenter for this meeting will be Mr. Joe Aranki, Program Coordinator for the Automotive Service Technology Department at the College of DuPage in Glen Ellyn, IL. Mr. Aranki is an ASE certified Master Technician as well as an experienced educator.
