Fuel System
Purpose, Outline A multiple hole type fuel injector has been adopted which provides higher fuel injection accuracy for improved fuel efficiency and output. Piston movement-compression by the 4-head cam inside the high pressure fuel pump heightens the fuel pressure, achieving imp ...

Oil Pressure Switch Inspection
1. Switch the ignition ON (engine off) and verify that the oil pressure warning light is illuminated. 2. Start the engine and verify that the oil pressure warning light turns off. If the oil pressure warning light is not illuminated or remains illuminated, inspect the wiring harness ...

Fuel Pump Control
Outline By switching the fuel pump discharge amount, reduced power consumption and improved fuel economy have been realized. The PCM determines the optimum fuel pump drive force according to the engine operation conditions, and sends the fuel pump drive signal to the fuel pump ...
