Powertrain Control Module (PCM): Notes
WARNING: This page does not describe the selected car, but rather 28 other vehicles, including the 2014 Lincoln Navigator, 2014 Lincoln MKZ, 2014 Lincoln MKX, 2014 Lincoln MKT, and 2014 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
The center of the engine control (EC) system is a microprocessor called the PCM. The PCM receives input from sensors and other electronic components (switches, relays). Based on the information received and programmed into its memory, the PCM generates output signals to control various relays, solenoids and actuators. There are several different types of PCMs in use for this model year. Refer to the Vehicle PCM Application Table below for PCM types and their applications.
