Cranking Signal: Description and Operation
PURPOSE
The ECU receives engine cranking indication when the starter solenoid is activated.
OPERATION
To provide starting enrichment, injectors are triggered 3 times per crankshaft revolution. The ECU also calculates any other applicable inputs when
calculating injector "ON" time during cranking. Enrichment is canceled at 200 rpm when coolant temperature is at or above 167°F (75°C) and at 500
rpm at lower temperatures.
