DESCRIPTION

The A/T fluid temperature sensor detects the A/T fluid temperature
and sends a signal to the TCM.

ON BOARD DIAGNOSIS LOGIC

Diagnostic trouble code

Malfunction is detected when ...

Check items

(Possible cause)

:

BATT/FLUID TEMP SEN

TCM receives an excessively low or
high voltage from the sensor.

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE

After the repair, perform the following procedure to confirm the
malfunction is eliminated.

1)

Start engine.

2)

Select “SELF-DIAG RESULTS” mode with CONSULT-II.

3)
