NOTICE:
Check around the quick connector for dirt or mud be-
fore this operation. Remove the dirt if necessary.
Be careful of mud because the quick connector has
an O-ring which seals the pipe and quick connector
that can be contaminated.
Do not use any tools in this operation.
Do not bend or twist the nylon tube. Protect the quick
connector by covering it with a vinyl or plastic bag.

FUEL SYSTEM (3MZ-FE)
PRECAUTION
1. PRECAUTION
(a) Before working on the fuel system, disconnect the engine wire No. 3 (battery negative terminal) from
battery.
(b) Do not smoke or work near open flame when working on the fuel system.
(c) Keep gasoline away from the rubber or leather parts.
2. DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:
Do not disconnect any parts of the fuel system pres-
sure until you have discharging the fuel system pres-
sure.
Even after discharge the fuel pressure, place a shop
rag over fittings as you separate them in order to re-
duce risk of fuel spray on yourself or in the engine
compartment.
(a) Disconnect the engine wire No. 3 (battery negative termi-
nal).
(b) Remove the circuit opening relay from the engine room
relay block.
(c) Connect the engine wire No. 3 (battery negative terminal).
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
(d) Start the engine. After the engine has stopped on its own,
turn the ignition switch OFF.
HINT:
There is a case that DTC P0171 (system to lean) is output.
(e) Check that the engine does not start.
(f) Remove the fuel tank cap, then let the air out of the fuel
tank.
(g) Disconnect battery negative terminal.
(h) Reinstall the circuit opening relay.
3. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline will spill out. So observe these proce-
dures.
(1) Work in order to prevent gasoline from spilling out.
(2) Disconnect the fuel pump tube (see page 11-20).
(3) Drain the fuel remaining inside the fuel pump tube.

ON-VEHICLE INSPECTION
1. CHECK FUEL PRESSURE
(a) Discharge the fuel pressure and take precautions against
possible fuel spillage (see page 11-1).
(b) Check that tha battery voltage is above 12 V.
(c) Disconnect the engine wire No. 3 (battery negative termi-
nal).
(d) Pull out the fuel tube connector from a new fuel tube.
HINT:
Part No. 23801-20190
(e) Remove the fuel pipe clamp.
(f) Disconnect the quick connector from the fuel pipe by
pinching portion A with your fingers as shown in the il-
lustration.
CAUTION:
After taking the precautions, disconnect the quick
connector.
As pressure remains in the fuel line, prevent it from
splashing inside the engine compartment.

(g) Install SST (a pressure gauge) and fuel tube connector
using SST as shown in the illustration.
SST 09268-41047 (95336-08070), 09268-45014
(09268-41250, 09268-41200, 09268-41220)
(h) Wipe up any gasoline.
(i) Reconnect the engine wire No. 3 (battery negative termi-
nal).
(j) Connect the hand-hand tester to the DLC3.
(k) Measure the fuel pressure.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
If the pressure is high, replace the fuel pressure regulator.
If the pressure is low, check the fuel hose connections, fuel
pump, fuel filter and fuel pressure regulator.
(l) Disconnect the hand-held tester from the DLC3.
(m) Start the engine.
(n) Measure the fuel pressure at idle.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
(o) Stop the engine.
(p) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure: 147 kPa (1.5 kgf/cm
2, 21 psi) or more
If the pressure is not as specified, check the fuel pump, pres-
sure regulator and/or fuel injectors.
(q) After checking the fuel pressure, disconnect the battery
negative terminal and carefully remove SST and the fuel
tube connector to prevent gasoline splash.
(r) Reconnect the No. 1 fuel pipe (the fuel tube connector).
CAUTION:
After taking the precautions, connect the quick connector.

INSPECTION
1. INSPECT FUEL INJECTOR ASSY
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Standard:
Tester ConnectionSpecified Condition
1 - 213.4 to 14.2 W at 20C (68F)
If the resistance is not as specified, replace the fuel injector.
(b) Check the operation.
CAUTION:
This test involves high-pressure fuel and electricity.
Keep the injector free of sparks during the test.
Take every precaution regarding safe handling of
both the fuel and electricity.
Perform this test in a safe area, and avoid any sparks
or flame.
Do not smoke.
(1) Pull out the fuel tube connector from a new fuel
tube.
HINT:
Part No. 23801 - 20190
(2) Connect SST and the fuel tube connector to the fuel
pipe.
SST 09268-41047 (95336-08070)
CAUTION:
After taking the precautions, connect the quick connector.
(3) Install the grommet and O-ring to the fuel injector.
(4) Connect SST (a union and hose) to the fuel injector,
then hold the fuel injector and union with SST (a
clamp).
SST 09268- 41047 (09268- 41110, 09268- 41300,
95336-08070)
(5) Put the fuel injector into a graduated cylinder.
HINT:
