PROCEDURE
1. FUEL PUMP ASSEMBLY OPERATION
(a) Check fuel pressure.
(1) Connect the Techstream to the DLC3.
(2) Start the engine.
(3) Turn the Techstream on.
(4) Enter the following menus: Powertrain / Engine / Active Test / Control the Target Fuel Pressure Offset.
Powertrain > Engine > Active Test
|
Active Test Display |
|
Control the Target Fuel Pressure Offset |
|
Data List Display |
|
Fuel Pressure (High) |
(5) Select the Data List item: Fuel Pressure (High)
(6) 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 (fuel delivery pipe with sensor assembly LH).
(b) Check operating sound.
(1) Remove the cowl top ventilator louver sub-assembly.
Click here
(2) Remove the front center upper suspension brace sub-assembly.
Click here
(3) Start the engine.
(4) Using a sound scope, check the operating sound of the fuel pump assembly.
If no sound can be heard, check the fuel pump assembly, wire harness and ECM.
(5) Stop the engine.
(6) Install the front center upper suspension brace sub-assembly.
Click here
(7) Install the cowl top ventilator louver sub-assembly.

CAUTION:
- Never perform work on fuel system components near any possible ignition sources.
- Vaporized fuel could ignite, resulting in a serious accident.
- Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.
- Sparks could cause vaporized fuel to ignite, resulting in a serious accident.
- To prevent serious injury due to fuel spray from the high-pressure fuel
lines, always discharge fuel system pressure before removing any fuel
system components.
PROCEDURE
1. PRECAUTION
NOTICE:
After
turning the engine switch off, waiting time may be required before
disconnecting the cable from the negative (-) battery terminal.
Therefore, make sure to read the disconnecting the cable from the
negative (-) battery terminal notices before proceeding with work.
