2GR-FXE FUEL: FUEL SYSTEM: ON-VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK
(a) Check fuel pump operation.
(1) Connect the Techstream to the DLC3.
(2) Turn the power switch on (IG).
NOTICE:
Do not start the engine.
(3) Turn the Techstream on.
(4) Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.
(5) Check for pressure in the fuel inlet tube from the fuel line. Check that sounds of fuel flowing from the fuel tank can be heard. If no sounds can be heard, check the integration relay, fuel pump, ECM and wiring connectors.
(b) Inspect for fuel leaks.
(1) Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.
(c) Turn the power switch off.
(d) Disconnect the Techstream from the DLC3.
2. CHECK FUEL PRESSURE
NOTICE:
w/ HDD Navigation System
After the power switch is turned off, the display and navigation module display (HDD navigation system) records various types of memory and settings. As a result, after turning the power switch off, make sure to wait for the time specified in the following table before disconnecting the cable from the negative (-) battery terminal.
Waiting Time before Disconnecting Cable from Negative (-) Battery Terminal
(a) Discharge the fuel system pressure Service Precautions.
(b) Using a voltmeter, measure the battery voltage.
Standard voltage:
11 to 14 V
(c) Disconnect the cable from the negative (-) battery terminal.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.
(d) Disconnect the fuel hose from the fuel main tube Service Precautions.
(e) Install SST (pressure gauge) using SST and a fuel tube connector as shown in the illustration.

SST : 09268-31012
09268-41500
90467-13001
95336-08070
SST : 09268-45014
09268-41200
09268-41220
09268-41250
(f) Wipe up any spilled gasoline.
(g) Connect the cable to the negative (-) battery terminal.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.
(h) Connect the Techstream to the DLC3.
(i) Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.
(j) Measure the fuel pressure.
Standard fuel pressure:
380 to 420 kPa (3.8 to 4.2 kgf/cm2, 55 to 61 psi)
* If the fuel pressure is greater than the standard value, replace the fuel pressure regulator.
* If the fuel pressure is less than the standard value, check the fuel hoses and connections, fuel pump, fuel filter and fuel pressure regulator.
(k) Disconnect the Techstream from the DLC3.
(l) Put the vehicle in the "inspection mode" Component Tests and General Diagnostics.
(m) Start the engine.
(n) Measure the fuel pressure at idle.
Standard fuel pressure:
380 to 420 kPa (3.8 to 4.2 kgf/cm2, 55 to 61 psi)
(o) Stop the engine.
(p) Check that the fuel pressure remains as specified for 5 minutes after the engine stops.
Standard fuel pressure:
147 kPa (1.5 kgf/cm2, 21 psi) or more
(q) If the fuel pressure is not as specified, check the fuel pump, pressure regulator and/or fuel injectors.
(r) After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST to prevent gasoline from splashing.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.
(s) Reconnect the fuel tube to the main fuel tube (fuel tube connector).
(t) Install the No. 1 fuel pipe clamp to the fuel tube connector.
(u) Inspect for fuel leaks (See step 1).
(1) Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.
