TRANSMISSION OIL COOLER INSTALLATION ± TC003±97 October 17, 1997
Procedure3. Final Assembly:
(Continued)
A. Reconnect the coolant temperature
switch connector and wire clamp as
illustrated in figure 14.
B. Install the cooling fan with 2 bolts.
C. Reconnect the cooling fan
connector and the No.1 engine
temperature switch wire connector
as shown in figure 15.
D. Reinstall battery and tray.
E. Start the engine.
F. With the engine at idle and the
brake pedal depressed, shift the
selector into all positions from ªPº to
ªLº, and return it to the ªPº position.
G. Check for leaks from the hose joints.
H. Add new fluid type ATF D´II or
DEXRON´III (DEXRON´II).
NOTE:
Additional capacity with cooler will be
0.38 US quarts (0.36 liters).
I. Shift the selector into all positions
from ªPº to ªLº, and return to ªPº.
J. Check fluid level with engine idling
at normal operating temperature of
158 to 176F (70 to 80C) and add
more fluid if required.
CAUTION:
Do not overfill.
K. Shut off the engine and reinstall the
center engine under cover with 9
bolts and 2 screws as shown in
figure 18.

O2S TEST RESULTS (MODE 05) ± SS002-03December 17, 2003
Page 2 of 43
1. Clear any stored Diagnostic Trouble Codes (DTCs) using the Toyota
Diagnostic Tester.
2. Start the engine.
3. Perform the drive pattern below to run and complete the Oxygen Sensor (O2S) Monitor.

HINT:
The O2S Monitor is completed when the following conditions are met:
Two (2) minutes or more passed after the engine start.
The Engine Coolant Temperature (ECT) is 167F (75C) or more.
Cumulative running time at 30 mph (48 km/h) or more exceeds 6 minutes.
Vehicle is in closed loop.
The fuel±cut is operated for 8 seconds or more (for Rear O2S Monitor).
A. Allow the engine to idle for two minutes.
B. Warm up the engine until the Engine Coolant Temperature (ECT) reaches 167F
(75C).
C. Drive the vehicle over 30 mph (48 km/h) for more than 40 seconds.
D. Stop the vehicle and allow the engine to idle for more than 20 seconds.
E. Repeat steps C and D at least 8 times in one driving cycle.
(Do not cycle the ignition key.)
In addition, perform the following steps for the Rear O2S Readiness Monitor:
A. Select second gear.
B. Allow the vehicle to run at 30 mph (48 km/h) or more.
C. Keep the accelerator pedal ªoff±idleº for more than 10 seconds.
D. Immediately after step C, release the accelerator pedal for at least 10 seconds
without depressing the brake pedal (to execute the fuel±cut).
E. Decelerate the vehicle until the vehicle speed reaches less than 6 mph (10 km/h).
F. Repeat steps B ± E at least twice in one driving cycle.

NOTE:
Before the O2S Monitor completes or after the ignition switch is turned OFF, the
Diagnostic Tester displays the viewable upper limit or a lower limit of the test value
(example: 0 V, 1.275 V, 0 s [seconds], 10.2 s, 0 and 255).
O2S TEST RESULTS (MODE 05) ± SS002-03December 17, 2003

1. Determine the correct O2S Failure Threshold Chart for your vehicle by looking in the
ªO2S Application Table,º pages 5 ± 9 in this bulletin.
2. Select appropriate year, model, and engine for specified O2S Failure
Threshold Chart.
3. Compare O2S test results with the specified O2S Failure Threshold Chart. It may be
necessary to convert O2S test results to a specific measurement unit using the
conversion factor that is supplied in the specified table. See example below:
Example:
A. The Diagnostic Tester displays
ª17º as a value of the ªTime $81º
(see illustration).
B. Find the Conversion Factor value
of ªTime $81º in the O2S Failure
Threshold chart below.
0.3906 is specified for Time $81
in this chart.
C. Multiply ª17º in step ªAº by 0.3906
(Conversion Factor) in step ªB.º
17 x 0.3906 = 6.6 %
D. If the answer is within the
Standard Value of TEST LIMIT,
the ªTime $81º can be confirmed
to be normal.

Time $84 84
Time $85 79
NOTE:
ªLOW SW Vº indicates the O2S
voltage when the O2S status changes
from rich to lean.
ªHIGH SW Vº indicates the O2S
voltage when the O2S status changes
from lean to rich.
If the O2S voltage is lower than
ªLOW SW V,º the O2S status is lean.
If the O2S voltage is higher than
ªHIGH SW V,º the O2S status is rich.
