2GR-FSE FUEL: FUEL PUMP (for High Pressure): ON-VEHICLE INSPECTION

ON-VEHICLE INSPECTION

1. CHECK FUEL PUMP OPERATION
(a) Check the fuel pressure.
(1) Connect the Techstream to the DLC3.
(2) Start the engine.
(3) Turn the tester ON.
(4) Enter the following menus: Power train / Engine and ECT / Active Test / Control the Target Fuel Pressure.
(5) Check that the fuel pressure fluctuates when the target fuel pressure changes.
HINT: The TARGET FUEL PRESS operation lowers the target fuel pressure by 12.5% or increases the target fuel pressure by 25%.

OK:
Fuel pressure fluctuates in accordance with tester operation.
If the result is not as specified, replace the fuel pump or fuel pressure sensor.
(b) Check the operating sound.
(1) Remove the V-bank cover.
(2) Start the engine.




(3) Using a sound scope, check the operating sound of the pump.
If no sound can be heard, check the fuel pump, wire harness and ECM.
