New or service sensors will already have the
compound
applied to the threads. If a sensor is
removed
from an engine and iffor any reason it
is to be reinstalled, the threads must have anti­

Apply anti-seize compound or equivalent to
threads of oxygen sensor if necessary.

STALL TEST
The stall test allows you to check the transmission for
internal abrasion and the oneway clutch for slippage.
Torque converter performance can also be evaluated.
The
stall test results together with the road test results
will identify transmission components requiring ser­
vicing or adjustment.
Stall Test Procedure:
1. Check the level of the engine coolant, the engine
oil, and the automatic transmission fluid.
Replenish
if necessary.
2. Block the wheels and set the parking brake.
3. Connect a tachometer to the engine.
4. Start the engine and allow it to idle until the
engine coolant temperature reaches
70 -8o·c
(158 -176.F).
5. Hold the brake pedal down as far as it will go.
6. Place the selector in the "D" range.
7. Gradually push the accelerator pedal to the floor.
The throttle valve
will be fully open.
Note the engine speed at which the tachometer
needle stabilizes.
Stall Speed
\fl NOTE:
2150 ± 150 rpm (SOHC)
2200 ± 150 rpm (DOHC)
VI Do not continuously run this test longer than 5
........, seconds.
8. Release the accelerator pedal.
9. Place the selector in the "N" range.
10. Run the engine at 1,200 rpm for one minute.
This
will cool the transmission fluid.
11. Repeat Steps 7-10 for the "3", "2", "L" and "R"
ranges.

LINE PRESSURE TEST
The line pressure test checks oil pump and control
valve
pressure regulator valve function. It will also
detect oil leakage.
Line Pressure Test Procedure:
1. Check the level of the engine coolant, the engine
oil, and the automatic transmission fluid.
Replenish
if required.
2. Block the wheels and set the parking brake.
3. Remove the pressure detection plug at the left
side of the transmission case.
Set pressure gauge, adapter
to the pressure
l"iC\1 detection plug hole. (Fig. 7 A-6a)

Start the engine and allow it to idle until the
engine
coolant temperature reaches 70 -80°C
(158-176°F).
Hold
the brake pedal down as far as it will go.
Place the selector in the "D" range.
Note the pressure gauge reading
with the
engine
idling.
Gradually
push the accelerator pedal to the
floor. The throttle valve will be fully open.
Note the pressure gauge reading
with the
accelerator
pedal fully depressed.
NOTE:
Do not continuously run this test longer than 5
seconds.
Release the accelerator pedal.
Place
the selector in the "N" range.
Run the engine at
1,200 rpm for one minute.
This
will cool the transmission fluid.
12. Repeat Steps 7-11 for the "3", "2", "L", and
"R" ranges.
13.
Install a pressure detection plug to the
transmission case,
applying recommended
thread
locking agent (LOCTITE 242) or its
equivalent to thread
of plug. Make sure that
thread is cleaned before applying locking
agents.
14. Tighten the pressure detection plug to the
specified torque.
