(7) Select the Data List item: Fuel Pressure (High).
(8) 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.

Random/Multiple Cylinder Misfire Detected (P030000,P030027,P030085-P030400)
DESCRIPTION When the engine misfires, high concentrations of hydrocarbons (HC) enter the exhaust gas. Extremely high hydrocarbon concentration levels can cause an increase in exhaust emission levels. Extremely high concentrations of hydrocarbons can also cause increases in the three-way catalytic co
