STEP 5. Check the transmission fluid temperature sensor
at A/T control solenoid valve assembly connector C-03.
(1) Disconnect connector C-03 and measure at the sensor
side.
(2) Measure the resistance between terminal 1 and 2.
• When transmission fluid temperature is 0°C (32°F),
resistance should be between 16.7 and 20.5 k
Ω.
• When transmission fluid temperature is 20°C (68°F),
resistance should be between 7.3 and 8.9 k
Ω.
• When transmission fluid temperature is 40°C (104°F),
resistance should be between 3.4 and 4.2 k
Ω.
• When transmission fluid temperature is 60°C (140°F),
resistance should be between 1.9 and 2.2 k
Ω.
• When transmission fluid temperature is 80°C (176°F),
resistance should be between 1.0 and 1.2 k
Ω.
• When transmission fluid temperature is 100°C (212°F),
resistance should be between 0.57 and 0.69 k
Ω.
Q: Is the measured resistance within the specified range?
YES : Go to Step 6.
NO : Replace the transmission fluid temperature sensor.

STEP 6. Using scan tool MB991502, check data list item 15:
Transmission Fluid Temperature Sensor.
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to the data link connector.
(2) Start the engine.
(3) Set scan tool MB991502 to data reading mode for item 15,
Transmission Fluid Temperature Sensor.
• When the engine is cool: Almost equal to the ambient
temperature (atmospheric temperature)
NOTE: Set scan tool MB991502 to data reading mode
for item number 13, Intake Air Temperature (IAT) Sensor
and note the temperature measurement. When the
engine is cool, the temperature should be almost equal
to the ambient temperature (atmospheric temperature),
and the IAT sensor measurement should be approxi-
mately the same as the transmission fluid temperature
sensor.
• When the engine is warm: 70 to 80°C (158 to 176°F)
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?
YES : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points
− How to Cope with
Intermittent Malfunction
NO : Replace the PCM.
STEP 7. Check A/T control solenoid valve assembly
connector C-03 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Are the connector and terminals in good condition?
YES : Go to Step 8.
NO : Repair or replace the damaged components. Refer to
GROUP 00E, Harness Connector Inspection

STEP 8. Measure the resistance of the ground circuit at A/T
control solenoid valve assembly connector C-03.
(1) Disconnect connector C-03 and measure at the harness
side.
(2) Measure the resistance between terminal 2 and ground.
• The resistance should measure less than 2 ohms.
Q: Is the resistance less than 2 ohms?
YES : Go to Step 5.
NO : Go to Step 14.

STEP 9. Measure the sensor output voltage at PCM
connector D-135 by backprobing.
(1) Do not disconnect connector D-135.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 119 and ground by
backprobing.
• When transmission fluid temperature is 20°C (68°F),
voltage should measure between 3.8 and 4.0 volts.
• When transmission fluid temperature is 40°C (104°F),
voltage should measure between 3.2 and 3.4 volts.
• When transmission fluid temperature is 80°C (176°F),
voltage should measure between 1.7 and 1.9 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage within the specified range?
YES : Go to Step 12.
NO : Go to Step 10.
