ON-VEHICLE INSPECTION
PROCEDURE
1. CHECK FOR FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK
(a) Check fuel pump operation.
(1) Connect the Techstream to the DLC3.
(2) Turn the ignition switch to ON and turn the Techstream on.
NOTICE:
Do not start the engine.
(3) Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.
(4) Check for pressure in the fuel inlet tube from the fuel line. Check that the sound of fuel flowing from the fuel tank can be heard. If no sound 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 ignition switch off.
(d) Disconnect the Techstream from the DLC3.
2. CHECK FUEL PRESSURE
(a) Discharge fuel system pressure.
HINT:
(See page ).
(b) Using a voltmeter, measure the battery voltage.
Standard Voltage:
Tester Connection |
Condition |
Specified Condition |
---|---|---|
Positive (+) terminal - Negative (-) terminal |
Ignition switch off |
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 (See page ).
(d) Remove the No. 1 fuel pipe clamp from the fuel tube connector. |
|
(e) Disconnect the fuel hose from the fuel main tube (See page ).
(f) Install SST (pressure gauge) as shown in the illustration. Text in Illustration
SST: 09268-31014 09268-41500 09268-41700 95336-08070 SST: 09268-45014 09268-41200 09268-41220 09268-41250 |
|
(g) Wipe up any gasoline.
(h) Connect the cable to the negative (-) battery terminal.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See page ).
(i) Connect the Techstream to the DLC3.
(j) Enter the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump / Speed.
(k) Measure the fuel pressure.
Standard fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm2, 44 to 50 psi)
(l) Disconnect the Techstream from the DLC3.
(m) Start the engine.
(n) Measure the fuel pressure at idle.
Standard fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm2, 44 to 50 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
If the fuel pressure is not as specified, check the fuel pump, pressure regulator and/or fuel injectors.
(q) After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST to prevent gasoline from spraying.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See page ).
(r) Reconnect the fuel tube to the main fuel tube (fuel tube connector).
(s) Install the No. 1 fuel pipe clamp to the fuel tube connector.
(t) Inspect for fuel leaks (See step 1).
If your vehicle needs to be towed
If towing is necessary, we recommend having your vehicle towed by your Toyota
dealer or a commercial towing service, using a lift-type truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/provincial and
local laws.
