Fuel Injector Pulse Width

The PCM adjusts fuel injector pulse width (air-fuel ratio) based on the following inputs:

• Battery Voltage
• Coolant Temperature
• Intake Air Temperature
• Exhaust Gas Content (Oxygen Sensor)
• Engine Speed (Crankshaft Position Sensor)
• Manifold Absolute Pressure
• Mass Airflow Sensor
• Throttle Position Sensors and Pedal Value Sensors
