adjustment. The ECU monitors engine conditions through inputs from a Manifold Absolute Pressure (MAP) sensor,
engine block temperature sensor and ignition timing.
EFI SYSTEM FEATURES/SPECIFICATIONS
• The fuel pump operating pressure is 50 psi +/- 3. The Kohler fuel pressure gauge has a psi variance of +/- 3.
• Fuel pump operates for a few seconds when key switch is turned to the ON position; it stops if no engine RPM
is detected by the ECU
• The ECU indicates a fault code through the malfunction indicator light (MIL)
• In-tank fuel pump
• Return-less system
• High fuel pressure system
• Controls fuel pump, fuel injector, and oil lamp
• Automatic altitude compensation
