INSPECTION PROCEDURE
HINT:
If DTC ”P0110” (intake air temp. circuit malfunction), ”P0115” (engine coolant temp. circuit malfunction) and
”P0120” (throttle/pedal position sensor/ switch ”A” circuit malfunction) are output simultaneously, E2 (sensor
ground) may be open.
TOYOTA hand−held tester:
1 Check for open in harness or ECM.
PREPARATION:
(a) Connect the TOYOTA hand−held tester to the DLC3.
(b) Disconnect the throttle position sensor connector.
(c) Connect sensor wire harness terminals between termi-
nals 3 and 4.
(d) Turn ignition switch ON.
CHECK:
Read CTP switch signal on the TOYOTA hand−held tester.
OK:
CTP switch signal: ON
OK Confirm good connection at sensor. If OK, re-
place throttle position sensor.

4. ROAD TEST
NOTICE:
Perform the test at normal operating ATF temperature 50 − 80°C (122 − 176°F).
(a) D position test
Shift into the D position and fully depress the accelerator pedal and and check the following points:
(1) Check up−shift operation.
1 → 2, 2 → 3 and 3 → O/D up−shift takes place, at the shift point shown in the automatic shift
schedule (See page SS−49).
HINT:
There is no O/D up−shift or lock−up when the coolant temperature is below 60°C (140°F).
Evaluation:
ProblemPossible cause
If there is no 1→2 up−shiftShift solenoid valve No.2 is stuck
1−2 shift valve is stuck
If there is no 2 →3 up−shiftShift solenoid valve No.1 is stuck
2−3 shift valve is stuck
If there is no 3 →O/D up−shift3−4 shift valve is stuck
If the shift point is defectiveThrottle valve, 1−2 shift valve, 2−3 shift valve, etc. are defective
If the lock up is defectiveShift solenoid valve SL is stuck
Lock−up relay valve is stuck
(2) Check for shift shock and slip.
Check for shock and slip at the 1 → 2, 2 → 3 and 3 → O/D up−shifts.
Evaluation:
ProblemPossible cause
If the shock is excessive
Line pressure is too high
Accumulator is defective
Check ball is defective
(3) Check for abnormal noises and vibration.
Run at the D position lock−up or O/D gear and check for abnormal noises and vibration.
HINT:
The check for the cause of abnormal noises and vibration must be done very thoroughly as it could also be
due to loss of balance in the differential torque converter clutch, etc.
(4) Check kick−down operation.
While running in the D position, 2nd, 3rd and O/D gears, check to see that the possible kick−down
vehicle 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−49).
(5) Check abnormal shock and slip at kick−down.
(6) Check the lock−up mechanism.
Drive in D position, O/D gear, at a steady speed (lock−up ON).
Lightly depress the accelerator pedal and check that there is lock−up.
If there is a big jump in engine speed, there is no lock−up.
(b) 2 position test
Shift into the 2 position and fully depress the accelerator pedal and check the following points:
(1) Check up−shift operation.
Check to see that the 1 → 2 up−shift takes place and that the shift point conforms to the automatic
shift schedule (See page SS−49).
