Engine Control Module: Description and Operation

Electronic Engine Controls

Electronic Engine Controls Locations:

The engine management system consists of a powertrain control module and a number of sensors and actuators. The sensors supply the powertrain control module with input signals which relate to engine operating conditions and the actuators respond to output signals from the powertrain control module. These output signals are based on the evaluated input signals which are compared with calibrated data tables or maps before the output signal is generated.

Powertrain Control Module (PCM)
The engine management system utilizes a 150 pin three connector design powertrain control module which provides precise control of basic engine calibration parameters. The powertrain control module controls the coil on plug ignition system, electronic returnless fuel system, digital transmission range control, cruise control and the electronic throttle control system.
