INSPECTION PROCEDURE
HINT:
If DTC P0105” (Manifold Absolute Pressure / Barometric Pressure Circuit Malfunction), ”P0110” (Intake Air
Temp. Circuit Malfunction), ”P0115” (Engine Coolant Temp. Circuit Malfunction), ”P0120” (Throttle / Pedal
Position Sensor / Switch ”A” Circuit Malfunction) are output simultaneously, E2 (sensor ground) may be
open.
1 Connect OBDII scan tool or TOYOTA hand−held tester and read the throttle valve
opening percentage.
PREPARATION:
(a) Connect the OBDII scan tool or TOYOTA hand−held tester to the DLC3.
(b) Turn ignition switch ON and OBDII scan tool or TOYOTA hand−held tester main switch ON.
CHECK:
Read the throttle valve opening percentage.
OK:

4. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand−held tester only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
(1) Clear the DTCs (See step 3).
(2) Set the check mode (See step 3).
(3) Do simulation test (See page IN−20).
(4) Check the connector connection and terminal (See page IN−30).
(5) Visual check and contact pressure (See page IN−20).
(6) Handle the connector (See page IN−20).
5. PROBLEM SYMPTOM CONFIRMATION
Taking into consideration the results of the customer problem analysis, try to reproduce the symptoms of the
trouble. If the problem is that the transaxle does not up−shift, down−shift, or the shift point is too high or too
low, conduct the following road test to confirm the automatic shift schedule and simulate the problem symp-
toms.
6. ROAD TEST
NOTICE:
Do the test at normal operating ATF temperature 50 − 80°C (122 − 176°F).
(a) D position test.
Shift into the D position, keep the accelerator pedal constant at the full throttle valve opening position
and check the following points:
(1) Check up− shift operation.
Check that 1 → 2, 2 → 3 and 3 → O/D up−shift takes place, at the shift point shown in the automat-
ic shift schedule (See page SS−32).
HINT:
O/D Gear Up−shift Prohibition Control:
Engine coolant temperature is 50°C (122°F) or less.
If there is a 10km/h (6 mph) difference between the set cruise control speed and vehicle speed.
O/D main switch is pushed ON (During the O/D OFF indicator light lights up.).
O/D Gear Lock−up Prohibition Control:
Brake pedal is depressed.
Engine coolant temperature is 50°C (122°F) or less.
(2) Check for shift shock and slip.
Check for shock and slip at the 1 → 2, 2 → 3 and 3 → O/D up−shifts.
(3) Check for abnormal noise and vibration.
Run at the D position lock−up or O/D gear and check for abnormal noise and vibration.
HINT:
The check for the cause of abnormal noise and vibration must be performed very thoroughly as it could also
be due to loss of balance in the torque converter clutch, etc.
(4) Check kick−down operation.
While running in the D position, 2nd, 3rd and O/D gears, check that the possible kick−down ve-
hicle speed limits for 2 → 1, 3 → 2 and O/D → 3 kick−downs conform to those indicated on the
automatic shift schedule (See page SS−32).
(5) Check abnormal shock and slip at kick−down.
(6) Check the lock−up mechanism.
Drive in the D position, O/D gear, at a steady speed (lock−up ON) of about 75 km/h (47
mph).
Lightly depress the accelerator pedal and check that the RPM does not change abruptly.
If there is a big jump in RPM, there is no lock−up.

O/D Cancel Signal Circuit
CIRCUIT DESCRIPTION
While driving uphill with cruise control activated, in order to minimize gear shifting and provide smooth cruis-
ing, O/D may be prohibited temporarily under some conditions.
The cruise control ECU sends O/D cur signals to the ECM as necessary and the ECM cancels O/D shifting
until these signals are discontinued.
