Toyota Camry (XV70): On-vehicle Inspection
ON-VEHICLE INSPECTION
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.

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.
