Toyota RAV4 Service Manual: Fuel system
Precaution
- Before working on fuel system
- Do not work near an open flame.
- Keep gasoline away from rubber and leather parts.
- Discharge the fuel pressure before disconnecting
the fuel line to prevent gasoline from spilling out.
Refer to the following procedure.
- Discharge fuel pressure
Caution:
- Discharge fuel system pressure
procedures must be performed before
disconnecting any part of the fuel system.
- After performing the discharge fuel system
pressure procedures, pressure will remain in
the fuel line. When disconnecting the fuel line,
place a cloth or equivalent over fittings to reduce
the risk of fuel spray.
- Remove the console box (see page ir-83).
- Disconnect the connector.
- Start the engine. After the engine has stopped, turn
the ignition switch off.
Hint:
Dtc p0171 (system too lean) may be set.
- Check that the engine does not start.
- Remove the fuel tank cap, and let the air out of the
fuel tank.
- Connect the connector.
- Install the console box (see page ir-90).
- Disconnect fuel main tube
Notice:

- Remove the fuel tube from the fuel hose clamp.
- Remove the fuel pipe clamp.
- Wipe off dirt on the fuel tube connector.
- Hold the fuel tube connector, and then install sst.
Sst 09268-21010
- Turn sst to align the retainer inside the fuel tube
connector with the chamfered part of sst.
- Insert sst into the fuel tube and hold it. Then push
the fuel tube connector toward sst side.
- Mount the retainer of the fuel tube connector onto
the chamfered part of sst.
- Slide sst and fuel tube connector together towards
the fuel tube until they make a click sound, and then
disconnect the fuel tube.
- Drain the fuel remaining inside the fuel tube.
- Cover the fuel tube and fuel pipe with a plastic bag
to protect the disconnected part.
- Connect fuel main tube
- Connect the fuel main tube.
- Push the fuel tube connector until it makes a "click"
sound.
- Install the fuel pipe clamp.
- Install the fuel tube to the fuel hose clamp.
- Disconnect fuel tube connector
- Wipe off any dirt on the fuel tube connector.
- Pinch the fuel tube connector, and then disconnect
the fuel tube. Do not use any tools.
- Drain the fuel remaining inside the fuel tube.
- Cover the fuel tube and fuel pipe with a plastic bag
to protect the disconnected part.
- Connect fuel tube connector
- Connect the fuel tube connector to the fuel pipe.
- Push the fuel connector until it makes a click sound.
Hint:
If it is difficult to connect the fuel tube connector, apply a small
amount of new engine oil on the tip of the pipe.
- Check for fuel leaks

On-vehicle inspection
- Check fuel pump operation
- Connect the intelligent tester to the dlc3.
- Turn the ignition switch on. Do not start the engine.
- Select the following tester menus: diagnosis,
enhanced obd ii, active test and fuel
pump/spd. Operate the fuel pump.
- Touch the fuel hose in the engine compartment to
check the fuel flow, and you will be able to hear the
sound of the fuel pump.
- Stop the fuel pump.
If there is no fuel flow, the fuel pump may not
operate. Check the fuel pump circuit (see page fu-
33).
- Check fuel pressure
- Check that the battery positive voltage is above 12
v.
- Discharge the fuel system pressure (see page fu-
9).
- Disconnect the cable from the negative (-) battery
terminal.
- Disconnect the fuel main tube (see page fu-10).
- Install sst (pressure gauge) as shown in the
illustration.
Sst 09268-31011 (95336-08070, 90467-13001,
09268-41500), 09268-45014 (09268-41200,
09268-41220, 09268-41250)
- Wipe off any gasoline.
- Reconnect the cable to the negative (-) battery
terminal.
- Start the engine.
- 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.
- 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.
- Reconnect the fuel main tube (see page fu-14).
- Check for fuel leaks (see page fu-14).
