Computerized engine controls are used to control [[FuelSystemEg fuel]], [[IgnitionEg ignition]] and [[EmissionsEg emission]] control systems. Engine 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 Accord and Prelude. On Civic and Civic Del Sol, ECU is located behind passenger-side kick panel.
**FYI:** Components are grouped into 2 categories. First category covers INPUT DEVICES, which control or produce voltage signals monitored by ECM. Second category is OUTPUT SIGNALS, which are components controlled by ECM.
**AC Switch Signal**
This switch signals ECM of demand for air conditioning. ECM then increases engine RPM to compensate for additional engine load.
EGR valve lift sensor detects amount of EGR valve lift and sends information to ECM. ECM uses this information, along with other sensor inputs, to determine regulation of [[EmissionsEg EGR control solenoid valve]].
TP sensor is a 3-wire potentiometer connected to throttle shaft. As throttle position changes, TP sensor varies [[SpecsEg voltage signal]] monitored by ECM. Sensor voltage ranges from about one volt at closed throttle to about 5 volts at wide open throttle.
