Control the Target Fuel Pressure Offset

Data List Display

Fuel Pressure (High)

(5) Check that the fuel pressure fluctuates when the target fuel pressure changes.

HINT:

The target fuel pressure operation decreases the target fuel pressure by 12.5% or increases the target fuel pressure by 24.8%.

If the result is not as specified, replace the fuel pump assembly or fuel pressure sensor.

(b) Check operating sound.

(1) Start the engine.

(2) Using a sound scope, check the operating sound of the fuel pump assembly.
