2000 TOYOTA CAMRY fuel filter

Fuel pumped up by the fuel pump, flows through the fuel filter and is distributed to each injector
at a set pressure maintained by the pressure regulator.
The fuel pressure regulator adjusts the pressure of the fuel from the fuel line (high pressure side)
to a pressure 284 kPa (2.9 kgf/cm
, 41 psi) higher than the pressure inside the cylinder head, and
excess fuel is returned to the fuel tank through the return pipe.
The pulsation damper absorbs the slight fluctuations in fuel pressure caused by fuel injector from
the injector.
The injectors operate on input of injection signals from the ECM and inject fuel into the cylinder
head.

2. CHECK FUEL PRESSURE
(a) Check that the battery voltages is above 12 volts.
(b) Disconnect the negative (±) terminal cable from the
battery.
CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the ªLOCKº
position and the negative (±) terminal cable is discon±
nected from the battery.
If there is no pressure, check the following parts:
wFusible link
wFuses (AM2 30A, EFI 15A, IGN 7.5A)
wEFI main relay
wFuel pump
wWiring connections (c) Check that there is pressure in the hose from the fuel
filter.
HINT: At this time, you will hear fuel return noise.
(e) Remove the SST.
SST 09843±18020 (d) Turn the ignition switch OFF.

Measure the fuel pressure.
Fuel pressure:
265 ± 304 kPa (2.7 ± 3.1 kgf/cm
, 38 ± 44 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the following parts:
wFuel hoses and connections
wFuel pump
wFuel filter
wFuel pressure regulator (e) Install the fuel inlet hose and SST (pressure gauge) to
the fuel filter outlet with 3 new gaskets and the union
bolt.
SST 09268±45012
Torque: 29 N±m (300 kgf±cm, 22 ft±lbf)
(f) Wipe off any splattered gasoline.
(g) Reconnect the battery negative (±) cable. (c) Put a suitable container or shop towel under the fuel
filter.
(d) Remove the union bolt and 2 gaskets, and disconnect
the fuel inlet hose from the fuel filter outlet.
HINT: Slowly loosen the union bolt.
(h) Using SST, connect terminals +B and FP of the data
link connector 1.
SST 09843±18020
(i) Turn the ignition switch ON.

5. DISCONNECT FUEL PIPE AND HOSE FROM FUEL
PUMP BRACKET
CAUTION: Remove the fuel filter cap to prevent the fuel
from flowing out.
(a) Using SST, disconnect the outlet pipe from the pump bracket.
SST 09631±22020
(b) Disconnect the return hose from the pump bracket. 3. REMOVE FLOOR SERVICE HOLE COVER
(a) Disconnect the fuel pump connector.
(b) Remove the 5 screws and service hole cover.
4. REMOVE FUEL PUMP LEAD WIRE
6. REMOVE FUEL PUMP BRACKET ASSEMBLY FROM
FUEL TANK
(a) Remove the 8 bolts.
(b) Pull out the pump bracket assembly.
(c) Remove the gasket from the pump bracket.

pump.
(c) Install the fuel pump by pushing the lower side of the
fuel pump.
(d) Install the fuel pump connector. 3. INSTALL FUEL SENDER GAUGE TO FUEL PUMP
BRACKET
(a) Install the sender gauge with the 2 screws.
(b) Connect the fuel sender gauge connector. 4. REMOVE CONNECTOR
Remove the 2 screws, connector support, connector
and gasket. 3. REMOVE FUEL PUMP FILTER FROM FUEL PUMP
(a) Using a small screwdriver, remove the clip.
(b) Pull out the pump filter.

(c) Install a new O±ring to the fuel inlet of pressure
regulator.
(d) Connect SST (hose) to the fuel inlet of the pressure
regulator with SST (union) and the 2 bolts.
SST 09268±41045 (09268±41090)
Torque: 5.4 N±m (55 kgf±cm, 48 ft±lbf)
(e) Connect the fuel return hose to the fuel outlet of the
pressure regulator with SST (union), 2 new gaskets
and union bolts. (a) Disconnect the fuel hose from the fuel filter outlet.
(b) Connect SST (union and hose) to the fuel filter outlet
with 2 new gaskets and union bolts.
SST 09268±41045 (90405±09015)
Torque: 29 N±m (300 kgf±cm, 22 ft±lbf)
HINT: Use the vehicle's fuel filter.
INJECTORS INSPECTION
1. INSPECT INJECTOR INJECTION
CAUTION: Keep injector clear of sparks during the test.
(f) California:
Remove the 2 O±rings, insulator and grommet from
each injector.
(g) Except California:
Remove the O±ring and grommet from each injector.

Check operation of VSV when battery positive
voltage is applied and released to the VSV termi±
nals.
Battery positive voltage is applied:
The air from port E is flowing out through the
air filter.
Battery positive voltage is not applied:
The air from port E is flowing out through port
G. (1) Disconnect VSV connector.
(2) Remove VSV.
(1) Measure resistance between terminals.
(2) Measure resistance between each terminal
and the body.
(1) Resistance: 33 ± 39
