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

1. CHECK FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

NOTICE:
Do not start the engine.

(c) Turn the Techstream on.

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

(e) Check the fuel pump operation.

(1) Check for pressure in the fuel inlet tube from the fuel line. Check that the sound of fuel flowing in the fuel tank can be heard.

If there is no sound, check the C/OPN relay, fuel pump, ECM and wiring connector.

(f) Check for fuel leaks.

(1) Check that there are no fuel leaks after performing maintenance anywhere on the system.

If there are fuel leaks, repair or replace parts as necessary.

2. CHECK FUEL PRESSURE

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

Standard voltage:

11 to 14 V

(b) Discharge the fuel system pressure Fuel System: Precaution.

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

(d) Disconnect the fuel tube Fuel System: Precaution.

(e) Install SST (pressure gauge) as shown in the illustration.

SST : 09268-31012

95336-08070

90467-13001

09268-41500

SST : 09268-45014

09268-41200

09268-41220

09268-41250

(f) Wipe up any gasoline.

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

(h) Start the engine.

(i) Measure the fuel pressure at idle.

Fuel pressure:

304 to 343 kPa (3.1 to 3.5 kgf/cm2, 44 to 50 psi)

If the pressure is not as specified, check the fuel pump and injectors.

(j) After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST and the fuel tube connector to prevent fuel from spilling.

(k) Reconnect the fuel tube Fuel System: Precaution.

(l) Inspect for fuel leaks Installation.
