Engine Control Module: Description and Operation
Cranking Enrichment
The ECU provides an increased pulse duration during engine cranking in addition to any enrichment due to the coolant temperature sensor or the cold
start injectors. The additional signal reduces slightly when cranking stops, but does not fall to normal level for a few seconds. This temporary enrichment
sustains the engine during initial running.
