Tribute 4WD L4-2.3L Hybrid (2008)
Engine Control Module: Description and Operation
POWERTRAIN CONTROL MODULE
The center of the electronic engine control (EEC) system is a microprocessor called the PCM. The PCM receives input from sensors and other electronic
components. Based on information received and programmed into its memory, the PCM generates output signals to control various relays, solenoids, and
actuators. The hybrid vehicle uses a 150-pin PCM which has 3 separate electrical harness connectors.
The PCM is located behind the instrument panel (cowl), center to both driver and passenger sides (access from the engine compartment).
