Fuel Injection System - I-TEC EFI: Description

The I-TEC control system constantly monitors and controls engine operation. This lowers emissions while maintaining fuel economy and driveability. The Electronic Control Unit (ECU) controls the fuel injection system, the ignition system, and the turbocharger control system (if used).

The ECU governs fuel injection operation by reading data from the following sensors: Oxygen sensor, crank angle sensor, vehicle speed sensor, coolant temperature sensor, airflow sensor, and throttle valve switch. The fuel delivery system consists of fuel tank, electric fuel pump, pressure regulator, and 4 fuel injectors.

NOTE: Fuel system operation will be covered. Refer to ISUZU I-TEC CONTROL SYSTEM article in COMPUTERIZED ENGINE CONTROLS section for additional information.
