On-Vehicle Inspection (to 12/2010)

2GR-FE FUEL: FUEL SYSTEM: ON-VEHICLE INSPECTION

1. CHECK FOR FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch on (IG).

NOTICE:
Do not start the engine.

(c) Turn the Techstream main switch on.

(d) Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.

(e) Check fuel pump operation while operating it with Techstream.

(f) Check that there is pressure in the fuel inlet hose.

If the fuel pump does not operate, release it.

(g) Check that there are no fuel leaks from any part of the fuel system.

(h) Turn the ignition switch off.

(i) Disconnect the Techstream from the DLC3.

2. CHECK FUEL PRESSURE

(a) Discharge fuel system pressure.

HINT
Fuel System: Precaution (to 12/2010).

(b) Using a voltmeter, measure the battery voltage.

Standard:

11 to 14 V

(c) Disconnect the cable from the negative (-) battery terminal.

(d) Disconnect the fuel hose from the fuel main tube Removal (to 12/2010).

(e) Install SST (pressure gauge) using SST and a fuel tube connector as shown in the illustration.





SST : 09268-31012

90467-13001

95336-08070

09268-41500

SST : 09268-45014

09268-41200

09268-41220

09268-41250

(f) Wipe up any gasoline.

(g) Connect the cable to the negative (-) battery terminal.

(h) Connect the Techstream to the DLC3.

(i) Start the engine.

(j) Measure the fuel pressure at idle.

Fuel pressure:

304 to 343 kPa (3.1 to 3.5 kgf/cm2, 44.1 to 49.7 psi)

* If the fuel pressure is greater than the standard value, replace the fuel pump.

* If the fuel pressure is less than the standard value, check the connection of the fuel hose and the fuel pump.

(k) Stop the engine.

(l) Check that the fuel pressure remains as specified for 5 minutes after the engine stops.

Fuel pressure:

147 kPa (1.5 kgf/cm2, 21 psi) or more

If the fuel pressure is not as specified, check the fuel pump or fuel injector.

(m) After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove the SST to prevent gasoline from splashing.

(n) Reconnect the fuel tube to the main fuel tube.

(o) Inspect for fuel leak Installation (to 12/2010).
