TRANSMISSION CONTROL SYSTEM (AW30–40LE) (V6 3.5L) 7A2-43
DTC P0712 (FLASHING CODE 15) Transmission Oil Temperature Sensor
Circuit Low Input
RTW37AMF000201
Circuit Description
The oil temperature sensor is a thermistor sensor that
is installed in the transmission case and converts
temperature changes into continuous electric signals,
then outputs them to the Transmission Control Module
(TCM). When the ATF temperature is low, the
resistance of the sensor (thermistor) goes up, so that
the voltage of the TCM signal becomes high.
As the ATF is gradually warmed, the resistance of the
sensor goes down and the voltage becomes low. At the
normal operating ATF temperature (80
C/176
F) of the
transmission, the voltage of the TCM is about 3.7V.
Condition for setting the DTC
The TCM detects following "Condition" for 5 min
continuously.
Condition ("Short"):
Oil temperature is more than 220
C (428
F).
Action Taken When The DTC Sets
The TCM judges oil temperature is 100
C (212
F).
Check Trans ON.
DTC stored.
Conditions For Clearing The DTC
The DTC can be cleared from the TCM history by
using a scan tool.
The DTC will be cleared from history when the
vehicle has achieved 40 warm-up cycles without a
failure reported.
After more than 1 second has elapsed after the
ignition key has been turned “ON", short between
No.11 and No.4 (ground) of DLC (Data Link
Connector). Then, after 1 second, but within 6
seconds, discontinue shorting.

Diagnostic Aids
Inspect the wiring for poor electrical connection at
the TCM. Look for possible bent, backed out,
deformed or damaged terminals. Check for weak
terminal tension as well. Also check for a chafed wire
that could short to bare metal or other wiring. Inspect
for a broken wire inside the insulation.
When diagnosing for a possible intermittent short o
r
open condition, move the wiring harness while
observing test equipment for a change.
Check oil temperature sensor for proper mounting
and adjustment.
