Electronic Control Unit (Ecu)
Computerized engine controls are used to control fuel, ignition and emission control systems. Electronic Control Unit (ECU) receives input signals from various sensors and components. ECU then compares each signal with a preprogrammed parameter in its memory. Based on this comparison, output signals are then adjusted to allow vehicle to perform optimally under all operating conditions. ECU is located under passenger-side carpet on all models.
NOTE:
Components are grouped into 2 categories. First category covers INPUT DEVICES, which control or produce voltage signals monitored by ECU. Second category is OUTPUT SIGNALS, which are components controlled by ECU.
