Legend Sedan V6-3206cc 3.2L SOHC FI (1995)
Engine Control Module/Powertrain Control Module: Description and Operation
Injector Timing and Duration
PURPOSE
The Engine Control Module (ECM) contains memories for the basic fuel injector discharge timing and duration at various engine speeds and
manifold pressures.
OPERATION
The basic discharge duration, after being read from memory, is further modified by signals sent from various sensors to obtain the final discharge
duration. The most vital of these sensors are: Engine Coolant Temperature (ECT) sensor, Intake Air Temperature (IAT) sensor, Manifold
Absolute Pressure (MAP) sensor, Heated Oxygen (HO2S) sensor, and the Barometric Pressure (BARO) sensor.
