WARNING: This page is about a different car, the 2004 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

INSPECTION START
Do you have CONSULT-II?

Yes or No
1. Yes: GO TO 2
2. No: GO TO 3
CHECK INPUT SIGNAL OF A/T FLUID TEMPERATURE SENSOR (WITH CONSULT-II)
With CONSULT-II
1. Start engine.
2. Select "TCM INPUT SIGNALS" in "DATA MONITOR" mode for "A/T" with CONSULT-II.
3. Read out the value of "FLUID TEMP SE".

1. Voltage
2. Cold [20°C (68°F)]->: Approximately 1.5V->
3. Hot [80°C (176°F)] 0.5V
OK or NG
1. OK: GO TO 4
2. NG: GO TO 5
CHECK INPUT SIGNAL OF A/T FLUID TEMPERATURE SENSOR (WITHOUT CONSULT-II)
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM terminal 47 and ground while warming up A/T.

  1. Voltage
  2. Cold [20°C (68°F)]->: Approximately 1.5V->
  3. Hot [80°C (176°F)] 0.5V
3. Turn ignition switch to "OFF" position.
4. Disconnect TCM harness connector.
5. Check continuity between TCM harness connector F57 terminal 42 (B/W) and ground.
  1. Continuity should exist.
  1. If OK, check harness for short to ground and short to power.

OK or NG
1. OK: GO TO 4
2. NG: GO TO 5
CHECK DTC
Perform "DTC P0710 A/T FLUID TEMPERATURE SENSOR CIRCUIT "

OK or NG
1. OK: INSPECTION END
2. NG:
  1. Perform TCM input/output signal inspection. See INPUT/OUTPUT SIGNAL OF TCM .
  2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
CHECK A/T FLUID TEMPERATURE SENSOR WITH TERMINAL CORD ASSEMBLY
1. Turn ignition switch to "OFF" position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminals 6 and 7 when A/T is cold.

4. Reinstall any part removed.
OK or NG
1. OK (With CONSULT-II): GO TO 2
2. OK (Without CONSULT-II): GO TO 3
3. NG:
  1. Remove oil pan.
  2. Check the following items:
  - A/T fluid temperature sensor
    1. Refer to "COMPONENT INSPECTION "
