(g) Apply a light coat of spindle oil or gasoline on the place
where a intake manifold touches an O±ring of the injector.
(h) Place the delivery pipes and fuel pipe together with the 6
injectors in position on the intake manifold.
(i) Temporarily install the 4 bolts holding the delivery pipes
to the intake manifold.
(j) Temporarily install the bolt holding the No.1 fuel pipe to
the intake manifold.
(k) Check that the injectors rotate smoothly.
HINT:
If injectors do not rotate smoothly, the probable cause is incor-
rect installation of O±rings. Replace the O±rings.
(l) Position the injector connector outward.
(m) Tighten the 4 bolts holding the delivery pipes to the intake
manifold.
Torque: 10 N´m (100 kgf´cm, 7 ft´lbf)
(n) Tighten the bolt holding the No.1 fuel pipe to the intake
manifold.

2. CONNECT NO.1 FUEL PIPE
(a) Align the alignment marks (white paint) on the No.1 fuel
pipe.
(b) Connect the No.1 fuel pipe (fuel tube connector) to the
fuel filter.
CAUTION:
Perform connecting operations of the fuel tube connector
(quick type) after observing the precaution.

INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and pipe connections are as shown in the illustra-
tion.
If a problem is found, repair or replace the parts as necessary.

TSB Revision Notice:
The information updated in this TSB is red
and underlined.
Under certain driving conditions, some 1MZ±FE equipped 1997 ± 1999 Camry California
Emission specification vehicles can exhibit a M.I.L. ªONº DTC P1133. An improved
Air/Fuel Ratio Sensor has been developed to correct this condition.

Should a M.I.L. ªONº condition with DTC P1133 be encountered, perform diagnostic
procedures as described in the Repair Manual.
If the problem source cannot be identified after checking all affected areas according
to the Repair Manual, the cause may be an Air/Fuel Ratio Sensor malfunction. In this
case, replace the Air/Fuel Ratio Sensor with the current part number listed above.
If the Exhaust Manifold threads are damaged by removal of the sensor, they can be
repaired by the proper use of a M18 x 1.5 tap.
