Input Speed Sensor
S Inspect resistance of each input speed senor be-
tween terminals.
Notice :
S Make sure to inspect resistance again at 20°C
(68°F) when resistance differ from standards ex-
cept 20°C (68°F).
S It might become infinity ohm when inspect resist-
ance at higher temperature.
Action : If the result of inspection is bad, replace ISS.
Transmission Range (TR) Switch
S Remove TR switch connector and inspect continuty
each range according to the conection chart.
Action : If the result of inspection is bad, replace the TR
switch.
Transmission Fluid Temperature Sensor
S Inspect the resistance between the terminals of
TFT sensor at 10°C (50°F) and 110°C (230°F).

* Description of Type
S Type A : TCM will request the illumination of MIL and store DTC when TCM detects a failure on the first ignition
cycle.
S Type B : TCM will request the illumination of MIL and store DTC when TCM detects failures on two consecutive
ignition cycle.
S Type D : TCM will not request the illumination of MIL or hold lamp, but will store DTC when TCM detects a failure
on the first ignition cycle.

FLUID COOLER FLUSHING
Flushing Procedure
1. Drain the fluid from the transaxle and refill the
transaxle with new transaxle fluid. Refer to ”Fluid
Drain Procedure” in this section.
2. Let the engine idle for 5 minutes.
3. Drain the fluid from the transaxle and refill the
transaxle with new transaxle fluid. Refer to ”Fluid
Drain Procedure” in this section.
CONTROL CABLE ADJUSTMENT
Adjustment Procedure
The various shift control cable positions must match at the
shift control lever in the vehicle and at the selector lever
on the transaxle to provide proper transaxle shifting.
Place the shift control lever in the PARK position and
check the selector lever connection to verify that it is in the
forward most position. If it is not, the following adjustment
must be performed:
1. Disconnect the negative battery cable.
2. Remove the floor console. Refer to Section 9G,
Interior Trim.
3. Place the shift control lever in the PARK position.
4. Loosen the control cable adjusting nut.
5. Move the Transmission Range (TR) switch lever
counterclockwise until stopping the lever.
